TTK 655 S commercial dehumidifier
The superlative of the Trotec standard series
Normal at Trotec, but still far from being the norm – The top model from our commercial dehumidifier standard series is truly outstanding in comparison with the competition:
The TTK 655 S can condense up to 150 litres per day. That is more than 6 litres per hour! This is made possible by a perfect cooperation of a high-performance heat exchange and fan system which can circulate and dehumidify air flow rates of 1,000 m³/h.
The powerful 1.9 kW compressor ensures a high dehumidification capacity in large rooms, even at room temperatures below 10 °C – and the high-quality hot gas automatic defrost of the TTK 655 S guarantees a much more efficient dehumidification performancewithout pausing on a time interval during which no dehumidification occurs.
"Dry-ve time music" – listen to it play...
Use it for construction drying today and clearing water damage tomorrow – common changes of location and use in rough construction site conditions are no problem for this condenser dryer:
The rotary compressor of the TTK 655 S not only makes it possible to transport it anywhere, it also allows you to start the dehumidifier immediately after positioning.
Transport is quick and easy thanks to the ergonomic construction and carriage design with a bar handle and large wheels. Uneven terrain and stairs are no problem. And the non-marking rubber wheels of the TTK 655 S leave no marks on your floorboards or other sensitive undergrounds.
To prevent hazardous dust or moisture from gathering on the electronics, not only the electronic components of the dehumidifier, but also all other components of the TTK 655 S are safely enclosed and attractively combined in the tried and tested German industrial design – protected prototype.

Clearly arranged control panel – protected by protective bars. (1)
The serial operating hours counter of the TTK 655 S commercial dehumidifier is optionally available as a dual counter for operating and kilowatt hours. (2)
A special enclosure reliably protects the TTK 655 S dehumidifier electronics from dangerous inclusions. (3)
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 655 S. This can be used to permanently drain condensation from whole stories of buildings. (5)
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
A handy protective cover is optionally available for all commercial dehumidifiers of the TTK-S series.

Investment protection for your drying devices
Particularly during construction drying operations in summer or when drying water damages, it is very likely that climate conditions arise which may significantly shorten the lifetime of condenser dryers – regardless of the make. We as manufacturer care about the fact that for process-related reasons your condenser dryers often have to be replaced much too soon, hence we have prepared a valuable practical recommendation relating to the investment protection of your drying devices.
