    Trotec TTK570ECO Dehumidifier

    Powerful dehumidification for construction, commerce, and water damage – efficient even at low temperatures.

    Not in stock

    A very powerful construction dehumidifier with brutal dehumidification strength. Perfect for drying large construction sites and for the effective drying of water damage. This dehumidifier has consistently omitted everything that is unnecessary for continuous operation. It has neither a display nor a hygrostat (a plug-in hygrostat can be optionally ordered if needed). This makes it very easy to operate, safe from tampering, and exceptionally affordable in price for this performance class. On the other hand, it has everything needed for quick drying: strong dehumidification performance, hot gas defrosting, hour counter, as well as large wheels and a handle for easy mobility on construction and damage sites.     Easy handling   "The commissioning is child’s play. Set up - connect the hose - plug in - flip the main switch - done!"   The operation continues until the dryer is reinstalled. As long as the device is connected to the power grid, it runs reliably and there are no settings that can be accidentally changed or manipulated. This also applies in the event of a power outage: when the power returns, the dehumidifier resumes its task with unchanged settings.   Thanks to the professional hot gas automatic control, operation in cooler environments is also possible without any issues, although the dehumidifying power, as with all condensation dryers, decreases at low temperatures. The installed finned evaporator (cooling element) has an exceptionally high efficiency in temperate environments and can dry the air to just below 40% relative humidity. Furthermore, the dryer is equipped with a rolling piston compressor. This means that it can be transported and stored in any position.     Optional Hygrostat   "Should a hygrometer for regulating the target humidity be required at any point, the dryer is prepared so that the Trotec Hygrostat HG110 can be connected directly via a jack plug. Please note the accessories."     Direct hose connection   With dryers of this strength, collecting water in an integrated bucket makes little sense, as it would constantly fill up. The water extracted from the air is therefore drained through a directly connected hose. The hose must be laid with a downward slope, as there is no pump integrated into the dryer. Freestanding condensate pumps are optionally available if the water needs to be transported upwards or over a distance.     Suitable for unattended continuous operation   This "TTK" is suitable for longer, unattended drying operations. The exact operating time can be precisely determined with the standard integrated hour meter. This is particularly useful for commercial applications. Thanks to the meter, it can also be tracked whether the device was always in operation or if it was accidentally or intentionally turned off.     Hydrofluorolefin (R-454C) as an environmentally friendly refrigerant in dehumidifiers   "Every year, several million tons of environmentally harmful CO2 emissions (greenhouse gases) are released into the air due to synthetic refrigerants. Therefore, the use of alternative refrigerants is one of our most important goals. By using hydrofluoroolefin (R-454C) as a refrigerant, this dehumidifier makes a valuable contribution to climate protection."   The natural refrigerant hydrofluoroolefin (R-454C) is an organic compound and belongs to the hydrocarbons. Unlike synthetic refrigerants, the environmentally friendly hydrofluoroolefin (R-454C) has neither ozone depletion potential (ODP=0) nor a significant greenhouse effect (GWP=146).    Supplement plus for the environment: Due to its excellent thermodynamic properties, hydrofluoroolefin (R-454C) is a particularly energy-efficient refrigerant, thereby additionally reducing your energy costs.   Advantages at a Glance   • Affordable price with strong performance in the commercial sector• Thanks to hot gas defrosting, it can also be used in cooler environments.• Robust steel construction with large wheels and guiding handle• Suitable for continuous operation• Thanks to the roll piston compressor, it is transportable and storable in any position.• External hygrometer connection     Technical data  dehumidification performance at 30 °C / 80 % r.H. 100 liters / day air volume 1000 m³/ h Maximum room size 250 m² (750 m³) Minimum room size 8 m² (30 m³) temperature range 5 - 32°C Moisture range technical Moisture Range Practice 30 - 90 % r.F. 40 - 90 % r.H.

    4 in stock

    The top dryer for larger spaces. The FDK performs reliable heavy-duty work in both cooler and temperate rooms.The operation is incredibly simple: a rotary knob for adjusting the desired target humidity and that's it. Everything else is done automatically by the device. For example, the FDK can utilize its dehumidifying power for year-round drying of garages, industrial halls, or in water management facilities. You can only get this model from us; comparable products on the market cost twice as much.Due to well-developed hot gas defrosting, the dryer is operational down to just above freezing point. Also very noticeable is its good performance in low humidity ranges, where it still extracts water from the air, while other dryers have long stopped producing any drops. Upon reaching the desired target humidity, the device completely shuts off and automatically restarts when the room humidity increases.The humid air is drawn in on one side of the housing and cleaned through an industrial, reusable filter. The dry air is blown into the room from the opposite side, creating an effective circulation in the room. Regarding placement in the room, many locations are conceivable. Both at floor level, somewhere on a free shelf, or mounted to the wall with brackets. When wall-mounted, the dryer can also be installed high up directly under the ceiling.The condensate is drained directly through the hose connection. The FDK100 stands on 4 (removable) rubber feet and has two foldable carrying handles on the top of the housing for easier mobility. When positioned close to the ground, the hose must have a continuous slope towards the drain so that it can drain cleanly and does not back up into the collection tray.The construction is solid and of high quality. The housing is made of white powder-coated metal, and the interior consists of components from the professional league. Therefore, the device is easily suitable for unattended continuous operation. In the event of a power failure, it resumes the dehumidification work with unchanged settings, making it suitable for operation with a timer or a smart home system.The FDK is suitable• as a dehumidifier for warehouses, commercial and industrial spaces, garages, and basements• for wall mounting or directly on the ceiling• for continuous dehumidification of temperate but also cold rooms from 1°C• for unattended continuous operation• for operation on a timer     dehumidification performanceThe dryer can be used over a wide temperature range from +1°C to +35°C thanks to its advanced hot gas defrosting, although, as with all condensation dryers, the dehumidifying power decreases in cooler environments.

  • Starker Luftentfeuchter Trotec TTK355S

    Trotec TTK 355 S Dehumidifier

    Powerful building dryer up to 55 l/day – ideal for large rooms, construction sites, and water damage.

    17 in stock

    Powerful Trotec TTK 355 S Dehumidifier for the Toughest Applications Whether for rapid reduction of high humidity or reliable drying of large rooms – the TTK 355 S is designed precisely for such challenges. The unit owes its impressive performance to the effective combination of a powerful rotary compressor and a quality fan that processes air volumes of up to 490 m³/h. This high air circulation allows the optimized heat exchanger system to continuously extract large amounts of moisture from the room air – up to 55 liters per day with just one unit. A special advantage is the integrated hot gas defrosting automatic system: It prevents dehumidification pauses due to fixed defrosting intervals, as is common with many other devices, thus ensuring consistent and efficient performance – even in cooler operating conditions. Features: High dehumidification performance (up to 55 L / day) Encapsulated electronics for dust & moisture protection Efficient hot gas defrosting automatic system Rotary compressor (transportable in any position) Stackable & multi-stackable thanks to groove guides Robust chassis with abrasion-resistant rubber wheels Integrated compressor overheat protection German industrial design with registered design protection Mobility & Well-Thought-Out Industrial Design The robust chassis with practical handle bar and large rubber wheels makes transport – even over stairs or uneven ground – incredibly easy. The installed rubber wheels are abrasion-resistant and leave no marks on delicate floor coverings. Thanks to rotary compressor technology, the TTK 355 S can be transported in almost any position. The technology is housed in a functionally designed, resistant casing in the distinctive Trotec industrial design – aesthetically pleasing, protected, and practical. The stackable design with practical groove guides on the top allows for space-saving storage and safe transport of multiple identical units. A special protection system shields sensitive electronic components from moisture and dirt. Safe Operation through Intelligent Compressor Overheat Protection During water damage restoration, extreme conditions with high humidity and high temperatures (above 35 °C) often prevail. This leads to a drastically reduced lifespan for conventional refrigeration dryers due to an enormous pressure increase in the refrigerant circuit. Therefore, the TTK 355 S is equipped with intelligent compressor overheat protection: Sensors continuously monitor temperature development. In case of overheating, the compressor automatically switches off while the fan continues to run. As soon as the system is back in the safe range, the compressor restarts operation independently. This sustainably extends the device's lifespan and protects the building structure. Advantages at a Glance 100 % Trotec – Development, Design, and Manufacturing High dehumidification performance, even at lower temperatures Protection of electronics from dust and moisture Maintenance-friendly design and easy handling Rotary compressor: transportable in any position Stackable and multi-stackable with identical models Integrated overheat protection for the compressor in extreme room conditions German industrial design with registered design protection Technical Data Dehumidification capacity at 20 °C / 60 % r.h. 27 Litres / Day Dehumidification capacity at 30 °C / 80 % r.h. 55 Litres / Day Air volume max. stage 490 m³/h Room size 140 m² / 350 m³ Temperature range min. 5 – 32 °C Humidity range min. 40 – 90 % r.h.

Frequently Asked Questions about Mobile Dehumidifiers

Does a dehumidifier help against mold?

Yes, a dehumidifier can help prevent mold formation and reduce mold growth. However, it does not remove existing mold. It is crucial to find and permanently fix the source of the moisture.

Excessively high humidity is one of the most common causes of indoor mold. A dehumidifier can lower the relative humidity, thereby worsening the conditions under which mold can thrive. This can be particularly useful in bathrooms, basements, bedrooms, or poorly ventilated rooms.

How does a dehumidifier help against mold?

Mold primarily needs moisture to spread. If the indoor air is consistently very humid, condensation can form on cold surfaces such as exterior walls, window reveals, or room corners. This is often where mold develops.

A dehumidifier removes water from the ambient air. This lowers the relative humidity and reduces the risk of moisture condensation on surfaces.

This means:

  • less moisture in the indoor air
  • less condensation on cold surfaces
  • poorer growth conditions for mold
  • lower risk of new mold formation
  • support for drying out damp rooms

Important: A dehumidifier is primarily a measure for moisture control. It does not remove existing mold infestation.

What is the ideal humidity to prevent mold?

For living spaces, a relative humidity of about 40 to 60 percent is often considered a reasonable range. Consistently significantly higher values can increase the risk of mold, especially if cold surfaces are present at the same time.

A hygrometer helps to control the humidity. If the relative humidity regularly rises above 60 percent, a dehumidifier can be a useful aid.

However, one should not try to keep a room permanently extremely dry. Excessively low humidity can also be uncomfortable and, for example, promote dry mucous membranes or irritated skin.

Can a dehumidifier remove existing mold?

No. A dehumidifier cannot kill existing mold or remove it from a wall.

If mold is already visible, the affected areas must first be professionally treated and, above all, the source of moisture must be eliminated. Otherwise, the mold can reappear after cleaning.

A dehumidifier can then help to keep the humidity at an appropriate level permanently.

Example

Suppose mold forms on an exterior wall in winter. The indoor air is very humid, and the wall surface is significantly cooled by the cold exterior wall. This can lead to moisture condensation there.

A dehumidifier can reduce the humidity. This lowers the amount of moisture that can deposit on the cold surface. However, this does not repair the cold wall or a possible structural cause.

When is a dehumidifier particularly useful?

A dehumidifier can be particularly helpful if high humidity is the actual cause of the problem.

Typical situations include:

1. Basements with high humidity

Basements are often cooler than the rest of the living areas. This can lead to condensation, especially in summer. A dehumidifier can help reduce humidity.

2. Bathrooms

When showering and bathing, a lot of water vapor enters the ambient air. If this is not adequately removed, the humidity rises sharply. A combination of ventilation and, if necessary, dehumidification can reduce the risk of mold.

3. Bedrooms

People also release moisture into the ambient air when breathing and sweating. Especially with closed windows, the humidity can significantly increase overnight.

4. Rooms with poor ventilation

In rooms without sufficient air exchange, moisture can accumulate. A dehumidifier can be used as a support here.

5. After water damage

After water damage, a powerful dehumidifier can help dry out rooms and materials faster. In the case of larger water damage, however, a specialist company should be consulted, as moisture can also be found in walls, floors, or insulation.

What is better against mold: ventilation or dehumidifier?

Both can be useful – depending on the cause of the moisture.

Regular and proper ventilation is one of the most important measures to remove excess moisture from living spaces. A dehumidifier can also be useful if the humidity remains too high despite adequate ventilation.

So-called shock ventilation is particularly important. This involves opening the windows wide for a short time to allow for rapid air exchange.

Permanently tilted windows are not always the best solution. In winter, they can cool down adjacent building components, while air exchange can be relatively inefficient.

Dehumidifier against mold: What needs to be considered?

A dehumidifier should not simply run continuously at maximum power. It is more sensible to measure the actual humidity with a hygrometer and set the device accordingly.

Pay particular attention to:

Measure humidity: A hygrometer shows whether there is even a problem with excessively high humidity.

Find the cause: High humidity can be caused by showering, cooking, drying laundry, or insufficient ventilation. However, it can also indicate water damage, a leaky pipe, or a structural problem.

Consider room temperature: Cold rooms and cold wall surfaces can increase the risk of mold, even if the average humidity of the room air does not initially appear extremely high.

Size the device correctly: A different device may be sufficient for a small room than for a large basement or a very damp room.

Empty the water tank regularly: For devices without a permanent drain, the collection tank must be checked regularly.

Which dehumidifier is suitable against mold?

Which technology is suitable depends, among other things, on room size and temperature.

Condensation dehumidifiers

Condensation units are often a practical solution for normally tempered living spaces. They remove moisture from the air and collect the water in a container or drain it through a hose.

They are suitable, for example, for:

  • Bedrooms
  • Bathrooms
  • Living rooms
  • Heated basements
  • Laundry rooms

Adsorption dehumidifiers

Adsorption units work differently and can be particularly interesting at lower temperatures. They are therefore also used, for example, in cool basements or other unheated rooms.

The choice of device should therefore not be based solely on the maximum dehumidification capacity. Room temperature, room size, and actual moisture load are also important.

Why does mold occur despite a dehumidifier?

If mold occurs despite a dehumidifier, one should look more closely for the cause.

Possible reasons include:

Thermal bridges

At thermal bridges, surfaces are often significantly colder than in the rest of the room. Condensation can form more easily there.

Leaky spots

Moisture can enter a building, for example, through leaky roofs, windows, pipes, or other building components.

Water damage

Water damage can cause building components to remain damp for a long time. A small room dehumidifier may then not be sufficient.

Incorrect ventilation and heating

Insufficient ventilation or strongly fluctuating room temperatures can promote the formation of condensation.

Furniture too close to the exterior wall

If furniture is placed directly against cold exterior walls, air circulation behind it can be restricted. This can lead to unfavorable moisture conditions there.

Does a dehumidifier also help against black mold?

A dehumidifier can worsen the moisture conditions for black mold, but it does not remove the mold.

Therefore, with visible mold, one should not simply place a dehumidifying device. It is crucial to professionally assess the affected area and eliminate the source of moisture.

For larger, recurring, or deeply ingrained mold infestations, professional help is advisable.

Can a dehumidifier prevent mold in the bedroom?

Yes, a dehumidifier can help prevent mold in the bedroom if there is consistently excessively high humidity.

Especially at night, humidity rises due to breathing. If the room is also poorly ventilated and cold exterior walls are present, condensation can form.

A sensible approach is therefore:

  1. Control humidity with a hygrometer.
  2. Ventilate regularly and effectively.
  3. Heat sufficiently.
  4. Do not place furniture directly against cold exterior walls.
  5. If humidity remains too high, use a suitable dehumidifier.
  6. Have existing moisture damage investigated.

Conclusion: Does a dehumidifier help against mold?

Yes, a dehumidifier can help against mold – but mainly preventively. It reduces humidity and can thereby worsen the conditions for mold growth.

However, existing mold is not eliminated by a dehumidifier. Therefore, anyone who wants to permanently avoid mold should not only dry the indoor air but also find and fix the cause of the moisture.

The most important combination is:

Control humidity + ventilate properly + heat sufficiently + eliminate moisture sources.

If humidity remains consistently high despite these measures or if mold repeatedly occurs in the same place, it should be checked whether there is a structural problem, a thermal bridge, or water damage.

What's the ideal humidity?

For living spaces, the ideal relative humidity is usually between 40 and 60%. Within this range, most people feel comfortable, and the risk of moisture problems and mold remains comparatively low.

Reference Values by Room

Ideal humidity 40–60%, temporarily higher after showering
Basement often 50–65%, depending on temperature and use

Permanently above 60% should be avoided if possible, especially in poorly insulated or cold rooms. Above approximately 70%, the risk of mold and other moisture problems increases significantly.

What to do if humidity is too high?

If your hygrometer consistently shows above 60%, for example:

  • ventilate regularly with bursts of fresh air
  • heat sufficiently
  • avoid drying laundry in living rooms if possible
  • extract moisture directly when cooking and showering
  • do not place furniture directly against cold outer walls
  • use a dehumidifier for persistently high humidity

Important: Not only the room air, but also cold surfaces are crucial. Even at seemingly acceptable 55–60%, condensation can form on a very cold outer wall, leading to mold.

In short: For most living spaces, 40–60% relative humidity is a good target range. If mold or recurring condensation occurs, the cause of the moisture should also be investigated.

Why are basements often damp in summer?

Cellars are often damper in summer because warm outside air contains much more moisture than cold cellar air. If this warm, humid air is let in through open cellar windows, it cools down in the cellar. The relative humidity can rise sharply – condensation can even form on cold walls. This increases the risk of mould.

What happens when you ventilate in summer

Imagine a cellar at about 15 °C. Outside, for example, it's 28 °C with 65% relative humidity.

The warm outside air enters the cellar through the open window. There it cools down to 15 °C. Because cold air can absorb less water vapour, its relative humidity rises sharply as it cools down.

In an unfavourable case, it reaches almost 100% – water then condenses on particularly cold surfaces.

That's why "open windows" in summer can even make a cellar damper.

Why are cellar walls particularly at risk?

Cellars are partially or completely underground and are therefore usually much cooler than the outside air. Typical problem areas are:

  • cold cellar walls
  • floors
  • corners
  • window areas
  • pipes
  • poorly ventilated areas behind furniture

If warm, humid air meets such cold surfaces, the so-called dew point can be reached. Then moisture condenses as water.

When should you ventilate a cellar in summer?

In summer, ventilating early in the morning or late in the evening is often more favourable than during the hottest and most humid time of day.

It is even better not to pay attention solely to the outside temperature, but to the dew point or the moisture content of the outside air. If the outside air is very humid, a cold cellar should be ventilated as little as possible with this air.

What helps against damp cellars in summer?

If the humidity in the cellar is permanently too high, the following measures can help:

  1. Install a hygrometer and regularly check the humidity.
  2. Do not leave cellar windows open permanently when the outside air is warm and humid.
  3. Ventilate briefly and intensely at suitable times.
  4. Use a dehumidifier if the humidity is permanently too high.
  5. Check sources of moisture such as leaky pipes or penetrating moisture.
  6. If recurrent dampness occurs on walls or floors, have the structural cause checked.

Rule of thumb: A cold cellar should not be "ventilated through" with warm, humid outside air in summer. Especially in humid weather, this can increase the moisture in the cellar and promote mould.

Which dehumidifier is suitable for basements?

Powerful mobile dehumidifiers with a humidistat and continuous operation are suitable for cellars. The appropriate device size depends on the room area, temperature, and humidity load. Please observe our recommendations regarding the maximum room size, which we declare for each device.

Can a dehumidifier help with drying laundry?

Yes, a dehumidifier can significantly assist with laundry drying. When drying, wet laundry releases a lot of water into the room air. This increases humidity, and the laundry dries progressively slower. A dehumidifier removes water vapor from the air, thereby creating better conditions for further evaporation.

This has two advantages: The laundry dries faster, and the humidity in the room remains lower. This also reduces condensation and the risk of mold.

How does it work?

The process is simple:

Wet laundry → Moisture enters the room air → Dehumidifier absorbs the moisture → Laundry can continue to dry.

This method is particularly practical when laundry is dried indoors, in the basement, or in a closed drying room.

What humidity level is suitable for drying laundry?

A range of approximately 40 to 60% relative humidity is a good target range. If the humidity consistently rises significantly above 60% during laundry drying, a dehumidifier can be beneficial.

A device with a hygrostat is particularly practical: it measures humidity and automatically regulates operation.

Dehumidifier or ventilation?

Both can work. In winter, ventilation is often very effective because cold outdoor air contains little absolute humidity. In summer, however, warm, humid outdoor air can be very damp itself. In this case, a dehumidifier is often the better solution.

When operating the dehumidifier, windows and doors should remain closed as much as possible to prevent new humid air from constantly entering the room.

How to dry laundry faster

  • Spin laundry as thoroughly as possible.
  • Hang clothes with sufficient space between them.
  • Do not cover the dehumidifier directly with laundry.
  • Ensure good air circulation.
  • Use a dehumidifier with a hygrostat.
  • In a cold basement, ensure the device is suitable for low temperatures.

Conclusion

A dehumidifier is a practical aid for drying laundry. It removes moisture from the room air, thereby accelerating drying, and can simultaneously reduce the risk of condensation and mold due to high humidity.

It is particularly useful when laundry is regularly dried indoors or in a closed basement room.

How much electricity does a dehumidifier use?

How much electricity a dehumidifier consumes depends primarily on power, operating time, room temperature, and humidity. A typical device with a power consumption of about 200 to 500 watts, for example, consumes 0.2 to 0.5 kWh per hour of operation.

Example Calculation

A dehumidifier with 300 watts operating for 8 hours requires:

0.3 kW × 8 hours = 2.4 kWh

At an assumed electricity price of 30 rappen per kWh, that would be approximately 72 rappen per day if the device actually runs continuously for eight hours.

In practice, however, a modern dehumidifier with a hygrostat often does not run continuously. As soon as the desired humidity is reached, the device automatically switches off or reduces its operation. This can significantly lower the actual power consumption.

What influences power consumption?

Particularly important are:

  • Power Consumption: A more powerful device consumes more electricity but completes the task faster.
  • Operating Time: The longer the dehumidifier runs, the higher the consumption.
  • Humidity: Very humid rooms require more dehumidification power.
  • Temperature: At low temperatures, some devices may operate less efficiently.
  • Room Size: Large or very humid rooms often require more power.
  • Hygrostat: Automatic humidity control can prevent unnecessary continuous operation.

How much does a dehumidifier cost per month?

For a device with 300 watts and, for example, 6 hours of actual operating time per day, the result is:

0.3 kW × 6 hours × 30 days = 54 kWh per month

At an electricity price of 30 rappen per kWh, this would be around 16.20 Swiss francs per month.

However, this is only an example calculation. The actual power consumption can be significantly higher or lower depending on the device and usage.

Are dehumidifiers energy guzzlers?

Not necessarily. While a dehumidifier requires relatively high power, it does not need to run permanently. An efficient device with a hygrostat can automatically adjust operation to the actual humidity levels.

However, especially when drying laundry or in a damp basement, a dehumidifier can still run for several hours a day. Therefore, when purchasing, it is worthwhile to pay attention not only to the maximum dehumidification capacity but also to energy efficiency and power consumption.

Conclusion

A typical dehumidifier consumes approximately 0.2 to 0.5 kWh per hour of operation, depending on its power. The actual electricity costs, however, depend crucially on how long the device runs.

A dehumidifier with a hygrostat, appropriate power, and automatic shut-off can help keep power consumption as low as possible.
