Comfort dehumidifier TTK 66 E

Perfectly combined: Dehumidifier and air cleaner with integrated ionizer

The comprehensive equipment of the TTK 66 E offers all the manifold high standards of the HomeComfort series. And the dehumidifier features even more exclusive extras.

This elegant dehumidifier coming in a deliberately plain white is worth every recommendation – for example in terms of its dehumidification performance. The TTK 66 E extracts up to 24 litres of moisture from the ambient air per day and is suited for rooms sized up to 50 m².

With a total of four operating modes, the TTK 66 E provides drier room air, which is more pleasant for the body. One operating mode is the hygrostat-controlled automatic dehumidification function with target values that can be set from 35 to 85 % relative humidity in convenient steps of 5 % – including an on-demand turbo blower. Another one is the special comfort function. In this mode, the TTK 66 E automatically controls the humidity level to a comfortable value depending on the temperature. Moreover, a laundry drying function and a continuous operating mode are available.

And best of all: The integrated ionizer can be activated in addition in every mode to ensure a better air quality. The ionizer produces negative ions that have an anti-static effect. The particles contained in the air are loaded negatively and sink to the floor as they are heavier than the ambient air. This way, the room air is cleaned and additionally enriched with active oxygen. Furthermore, the negative ions have a stimulating effect on humans and ensure general well-being. In the nature, these ions primarily occur in forests, coastal regions or at waterfalls – thus at places where people feel particularly comfortable and can take a deep breath.

In case of an unexpected switch-off due to a power interruption, the auto restart function makes the device restart with the previously selected setting as soon as the power supply has been restored. Thus, the TTK 66 E is also suited for combined use with a timer.

The variety of functions is completely by a practical timer function, a filling level warning light to indicate a full water tank, an overflow protection with automatic switch-off and others.  A discreet window at the front is another special feature of the dehumidifier allowing you to visually check the water tank's filling level. The washable air filter and a drainage connection enabling unattended continuous operation top off the convenient features of the TTK 66 E and allow for an extremely simple use of the device. And even a change of location becomes a pure pleasure with this dehumidifier – thanks to the practical cable holder, integrated carrying handles and steerable wheels.
