This extendable rail simplifies the attachment of the exhaust hose to windows with roller shutters and increases the cooling efficiency of mobile air conditioners. It is easily braced into the guide rails on the left and right and can be precisely extended in width up to a maximum of 136cm. The window cover visually harmonizes perfectly with white windows, allowing for an almost invisible discharge of warm air through the window from the outside. The exhaust hose must have a diameter of Ø15 cm; thinner or thicker hoses do not fit this system. The connection nozzle can be placed in either the left or right area.    Advantages at a Glance   • Particularly simple and visually appealing attachment of the exhaust hose to the window• The cooling efficiency of the air conditioning is increased, as less warm air from outside enters the room.• Uncomplicated installation without craftsmen• Stop hanging exhaust hoses out of the windows• Adjustable variable for window widths of approx. 47 to 136 cm     "The following models from our range are compatible:" • Argo: Argo Chronos • Trotec: PAC Series PAC 2100 X, PAC 2600 X, PAC 3000 X A+, PAC 3500 SH, PAC 3900 X     "For casement windows and casement doors as well as tilt windows and tilt doors, please consider our 'HotAirStopper' as a suitable solution." Trotec Article No. 6.100.000.039

Ideal for venting the moist warm air from 2-hose air conditioning units. The exhaust hoses are installed in 99% of all cases at an open window."Without an intelligent window installation, such a solution operates extremely inefficiently, as warm outside air continuously flows back in through the window opening, partially negating the cooling performance of the air conditioning unit. In other words: Your mobile air conditioner must not only cool the warm indoor air but also the incoming outside air. This clever sealing fabric significantly increases energy efficiency." This practical helper can be attached to any type of window with just a few simple steps and reliably prevents the backflow of warm outside air into the air-conditioned interior, as well as the intrusion of insects. When installed correctly, the window can be closed as usual without having to remove the fabric. The translucent fabric is made from a durable and water-repellent material with low thermal conductivity. This increases cooling efficiency and reduces consumption costs. The acquisition costs have already paid off in a very short time.  Easy construction  The sealing cloth is attached using the included Velcro tape, which can be removed at any time, similar to mosquito nets. Cleaning in the washing machine is also easily possible.  Suitable for air conditioning units with dual hose technology Air conditioning units with dual hose technology operate with two separate air paths. Commercially available window seals usually only have a zipper opening and are therefore not suitable for use with dual hose devices. This "Airlock" has two openings, allowing for the variable attachment of one "or" two exhaust hoses. If only one opening is needed, the zipper closes the second one invisibly and airtight.  Maximum circulation 560 cm The sum of the three open sides must not exceed 560 cm for this model. This is usually sufficient to also encompass tilted balcony doors. For standard-sized windows, please also consider the model "Airlock200."  Advantages at a Glance • Increases cooling performance, reduces energy consumption• Suitable for large casement windows, large tilt windows, and tilted balcony doors • For air conditioning units with single hose and dual hose technology• Prevents the intrusion of warm air and insects• The window can be closed despite the window sealing.• Amortizes in no time at all• Easy self-assembly  Trotec Article No. 6.100.002.004

PAC-W 2650 SH Wall-Mounted Air Conditioner – Cooling & Heating Without an Outdoor Unit The year-round solution for your rented apartment or home office: The PAC-W 2650 SH efficiently brings rooms up to 34 m² to a comfortable temperature. In summer, it cools with 2.6 kW; in winter, it heats thanks to state-of-the-art heat pump technology – all without a disruptive outdoor unit on the facade. The PAC-W 2650 SH is the perfect solution where traditional split systems are not permitted. For installation, two discreet drill holes in the outer wall are sufficient – no refrigerant installation by specialists is necessary. Efficient Heating with Heat Pump Technology Unlike conventional electric heaters, this device operates with a highly efficient air-to-air heat pump. With a COP value of 3.1, the device converts just 0.7 kW of power consumption into a solid 2.3 kW of heating capacity. This is about three times more efficient than a normal fan heater. Landlord-Friendly: Since no outdoor unit needs to be installed, the appearance of the facade is maintained. When moving, the drill holes can be sealed, and the device simply moves with you. Maximum Comfort: App Control & Night Mode Thanks to integrated Wi-Fi and the Trotec app, you can conveniently control your indoor climate from your smartphone – even when you're out and about. The night mode ensures an undisturbed sleep: the device operates particularly quietly (max. 48 dB(A)) and gently adjusts the temperature. Environmentally Friendly & Future-Proof The PAC-W 2650 SH uses the natural refrigerant R290 (propane) with a GWP value of only 3. This means the device already meets the strict EU environmental requirements for 2030 and operates in a particularly climate-friendly manner. Your Advantages at a Glance 4-in-1 device: Cooling, Heating, Ventilation, and Dehumidification No outdoor unit necessary – ideal for rented apartments & listed buildings Inverter technology for up to 30% energy saving 2.6 kW cooling capacity / 2.3 kW heating capacity Control via WiFi & Smartphone App Flat design (only 20.5 cm deep) Includes 24-hour timer & swing function 2-year warranty Technical Specifications Feature Specification Recommended room size up to 34 m² / 85 m³ Cooling capacity max. 2.6 kW (9000 Btu/h) Heating capacity max. 2.3 kW (COP 3.1) Energy efficiency class A (Cooling) Refrigerant R290 (290g) Sound level (1m distance) approx. 48 dB(A) Operating range outside -5 °C to +35 °C Outer wall drill holes 2x Ø 180 mm Dimensions (W x H x D) 1000 x 585 x 205 mm Weight 40 kg Frequently Asked Questions (FAQ) Do I need an HVAC technician?No. Since the system is a closed monoblock, no handling of refrigerant lines is necessary. Installation can be carried out by skilled individuals themselves. Is the device a full heating system in winter?Thanks to the heat pump, the device can heat very efficiently down to an outside temperature of -5 °C. It is ideal as supplementary heating or for rooms that need to warm up quickly.
