Product Description for TTK 355 S Dehumidifier
Reducing high humidity levels in the shortest time or keeping large rooms dry with ease - this is where the TTK 355 S belongs, and that's what it was designed 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 490 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 trolley design with handle bar and large wheels, the TTK 355 S can also be easily transported over rough terrain or up and down stairs - the rolling piston compressor technology enables transport in virtually any position. And indoors, the non-staining rubber wheels leave no marks on parquet or other sensitive surfaces.
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 neatly combined in practice-optimised 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.
Benefits in practice:
- Development, design, production: 100 % Trotec
- High dehumidification performance even at low temperatures
- Maximum dust and dampness protection for all electrical components
- Very maintenance friendly design
- 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
Active value retention through integrated compressor heat protection with automatic switch-off.
In drying applications with extremely high humidity and in high temperatures - for example in water damage restoration - refrigeration dryers quickly reach their red capacity range. The catchy "35 rule" applies here: drying water damage above 35 degrees reduces the dryer service life to below 35 %!
However, this is not a question of component quality, but pure physics that applies to all refrigeration dryers on the market, regardless of the manufacturer.
While most professional condensation dryers can still operate without problems up to 35 °C at moderate humidity levels of around 70 % RH, very high humidity levels combined with high room temperatures result in significantly more energy being supplied to the humid room air, which must additionally be "worked off" via the refrigerant.
As a result, the pressure of the refrigerant in the system increases immensely, which leads to a destructive load on the compressor.
The dehumidifiers will initially continue to operate, but well above their limit "deep in the dark red range", resulting in an extremely shortened remaining service life.
Nevertheless, there is no way around the use of a condensation dryer for such drying tasks, because adsorption dehumidifiers consume considerably more energy here with the same drying performance and are therefore not a sensible alternative, especially from an economic point of view.
That is why the commercial dehumidifiers of the TTK-S series have integrated compressor heat protection to actively preserve the value of your appliances:
Sensors permanently monitor the heat load of the compressor. If the temperature is within the defined operating range, the integrated heat protection indicator pulses in a long sequence, indicating optimum operation of the dehumidifier.
As soon as the temperature exceeds the critical limit of 35 °C, the automatic system switches the compressor off for its protection while the fan continues to operate and automatically activates the compressor again as soon as the temperature falls below the 35° limit again.
This protection not only significantly extends the life of the dehumidifiers, it also prevents thermal damage to materials in the room and the building structure during their use.
