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.

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 air flow rates of up to 1,000 m³/h.

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.

A few practical benefits:

  • Development, design, production: 100 % Trotec
  • High dehumidification performance even at low temperatures
  • Maximum dust and dampness protection for all electrical components
  • Very easy to maintain construction
  • Optimal handling
  • Portable and easily stored anywhere thanks to its rotary compressor
  • Practical stacking groove for stable, space-saving storage and transport
  • Stackable with equally dimensioned models
  • Tried and tested German industrial design – protected prototype
