The new value-for-money leader in the 70-litre class Reduce high levels of relative humidity in minimum time or easily keep large rooms dry – the TTK 355 S is in its element, this is what it was made for.

This becomes possible because of a clever combination of a strong 1.27 kW rotary compressor and a quality fan for airflow rates of up to 1,000 m³/h.

Watch our video below on how to setup the handle on the Trotec TTK 355.

	10°C	12 litres	20.4 litres
	15°C	18 litres	31.2 litres
	20°C	27.6 litres	40.8 litres
	25°C	31.2 litres	48 litres

Thanks to the high air circulation, the tuned heat exchange system is always able to feed extreme humidity from the ambient air for quick drying. Up to 70 litres of humidity can be removed from the room air per day with just one TTK 355 S in this manner.

At the same time, compared with other defrost systems, the high-quality hot gas automatic defrost of the TTK 355 S guarantees a much more efficient dehumidification performance without defrost pauses on a time interval during which no dehumidification occurs.

Common location changes and use in rough construction site conditions are no problem for this condenser dryer: Thanks to the ergonomic construction and carriage design with a bar handle and large wheels, the TTK 355 S can easily be transported over uneven terrain or up and down stairs – the rotary compressor makes it possible to transport it anywhere. And the non-marking rubber wheels leave no marks on your floorboards or other sensitive undergrounds.

A special enclosure protects the electronic components of the dehumidifier from hazardous dust or moisture, which can interfere with the functionality and durability of the electronics.

The enclosure is in no way inferior to the impressive inner values: All components of the TTK 355 S are reliably protected and attractively combined in the tried and tested German industrial design – protected prototype.

Even in storage, the TTK 355 S makes a good impression – while taking up surprisingly little space. Due to its two practical stacking grooves on top, equally sized TTK‑S devices can be safely stacked to save space during transport and storage.

Two stacking grooves make it possible to stably stack equally sized TTK‑S commercial dehumidifiers to save space. (4)

A powerful condensate pump with a pump performance of up to 50 m distance and a maximum pump height of 4 m is also available for permanent drying with the TTK 355 S.

This can be used to permanently drain condensation from whole stories of buildings. (5)

 

COMMERCIAL DEHUMIDIFIERS OF THE TTK-S SERIES The new standard class – top of the class.

Robust metallic housing, strong rotary compressors, low-maintenance construction, high airflow rate and wide range of usable temperatures: Whether for use in a workshop, in construction, in storage or in a laboratory – the portable, commercial dehumidifiers of the TTK S series are the perfect drying aggregates for changing applications, even in rough conditions.

With the pioneering TTK S commercial dehumidifiers, you can now benefit from a variety of detailed solutions which save you time, enhance your performance and secure value retention – attractively combined in the tried and tested German industrial design – protected prototype.

Also protected – from dust and dampness, that is – are all electrical components of the devices. A special enclosure improves the protection of the electronic equipment from anything dangerous which may enter and impair the functionality and durability. This enclosure makes the commercial dehumidifier predestined for use in harsh conditions.

Due to its extremely low-maintenance construction, the new TTK S generation is easier to clean than ever before and due to its low power to weight ratio and its clever mobility features, it is easy to transport.

Nevertheless, in terms of dehumidification capacity, these dryers are no lightweights: The entire heat exchange system made of high-quality components was designed to work in harmony and guarantees the maximum drying efficiency of the devices in all temperature ranges – for example, even under 15 °C in unheated rooms.

Furthermore, compared with other defrost systems, the high-quality hot gas automatic defrost guarantees a much more efficient dehumidification performance without defrost pauses on a time interval during which no defrosting occurs!

Even in the storage, these commercial dehumidifiers make a good impression – while taking up surprisingly little space. Because they are equipped with two practical stacking grooves on their tops, equally sized TTK S devices can be safely stacked to save space during transport and storage.
