TTK 900 MP – Professional Construction Dryer for Demanding Applications High-performance construction dryer for commercial use and water damage restoration. Featuring VarioDry technology, two-point hot gas defrosting, and environmentally friendly R-454C refrigerant. The TTK 900 MP is a professional construction dryer developed for extremely demanding applications. Its robust construction and high-quality components ensure consistently high dehumidification performance and lasting value. A powerful rotary compressor combined with a high-pressure radial fan provides maximum dehumidification capacity – even at low ambient temperatures. Thanks to dual-sided dry air discharge, the radial fan distributes the dehumidified air evenly throughout the room without back pressure, enabling extremely fast drying of large areas. A true highlight is the innovative VarioDry technology: It allows the device to be optimally adapted to the respective application environment via a switch – either for efficient new building drying or targeted water damage restoration. Features: 10% more power with 10% less energy consumption (vs. TTK 800) VarioDry technology for new building drying & water damage Two-point hot gas defrosting via bypass process High-pressure radial fan with dual-sided air discharge Climate-friendly R-454C refrigerant (GWP < 150) Encapsulated, modular electronics with plug connections Robust metal housing & adjustable push handle Transportable standing and lying down, as well as stackable Integrated operating hours counter Prepared for external hygrostat & pump connection Efficiency, Mobility & Sustainability Maximum drying efficiency is ensured by the two-point hot gas defrosting via bypass process, which drastically shortens defrosting times and extends active drying cycles – ideal for unheated construction sites. With an excellent energy coefficient, the TTK 900 MP achieves outstanding dehumidification performance per kilowatt. The device also sets standards in terms of service: The metal casing can be quickly removed thanks to the innovative central chassis. The encapsulated electronics are modular and pluggable, allowing for easy replacement of components directly on site.
