Comfort dehumidifier TTK 122 E

Magnificent design for drying larger rooms

It neither rests, nor rusts – but makes a good impression even when used in rough and cold surroundings!

The TTK 122 E is equipped with a high-quality hot gas automatic defrost, which, in contrast to electronic defrost units, ensures a much more efficient dehumidification performance – particularly at low ambient temperatures – without defrost pauses on a time interval during which no defrosting occurs. Therefore, this condenser dryer is also suited for the dehumidification and dry keeping of unheated basements or storage spaces.

Its robust stainless steel housing can withstand even the harshest of conditions in the application environment. Ideal conditions for instance for the application in frequently changing locations on building sites or for clearing water damage.

Owing to the rubber-tyred swivel casters and bar handles on both sides the TTK 122 E can be transported without difficulty. Nevertheless, the sound processing is not achieved at the expense of user comfort, quite on the contrary – the TTK 122 E's control panel with easy-care membrane keys for instance enables the direct input of the desired humidity value via the digital display. A practical, energy-saving benefit as opposed to analogously controlled dehumidifiers with mere unitless selection using a rotary switch.

For climate control the current air temperature and humidity values prevailing in the room can also be indicated on the display of the TTK 122 E during operation.

As alternative to fully automatic operation a special SuperDry function for an accelerated drying of textiles can be set as well – this is particularly handy for the quick dehumidification of wet laundry, clothes or carpets.

Moreover, a filling level warning light to indicate a full water tank, an overflow protection with automatic switch-off function and a reusable air filter, which is easy to clean, also belong to the standard equipment of the TTK 122 E.

For applications, where regular draining of the 10 l water tank is not an option, e.g. for unattended permanent drying in holiday homes or on boats, the TTK 122 E comes equipped with an integrated hose connection for direct discharge of the condensate into a drain. The hose required for this is already included in the standard scope of delivery.
