Comfort dehumidifier TTR 57 E

Easily keep an eye on the humidity level – even in unheated rooms.

The timelessly elegant desiccant dehumidifier TTR 57 E recommends itself as an ideal solution for the permanent dehumidification and dry keeping of even unheated rooms sized up to 20 m². When conventional condenser dryers can only achieve an insufficient or inefficient dehumidification due to the low room temperatures, the desiccant dehumidifier TTR 57 E can play to its strengths even at temperatures of as low as 1 °C. Another advantage of the tried and tested desiccation technique: The TTR 57 E requires neither compressor nor cooling agent or defrost pauses. Its operation is agreeably energy-efficient and does not generate any distracting noises.

With LED colour indication of the optimum humidity level

A quick glance instantly lets you know whether the room humidity level is in the green range. The colour LED display at the device front visualizes the current humidity level in an appealing manner:

Ideally, the room's humidity level ranges between 50 % and 70 %.

Optimum humidity level at 50–70 %

The air is very dry, the humidity level amounts to less than 50 %.

Too dry at less than 50 %

The air is very humid, the humidity level exceeds 70 %.

Very humid at more than 70 %

Variably applicable – also for drying laundry

The dehumidifier TTR 57 E is excellently suited for the dehumidification of cold basement rooms, for instance to prevent damp walls and harmful mould growth. In the unheated garage the TTR 57 E reduces the humidity level so as to protect the cardboard boxes stored there or to prevent the formation of rust. In the conservatory the dehumidifier helps to fight the unwelcome condensation forming on the glass and used on boats it prevents the harmful moisture inside the cabins. The variability of the TTR 57 E is completed by a convenient assistance mode for drying damp laundry in living rooms, bedrooms or utility rooms.

High dehumidification performance

Equally impressive as the numerous application possibilities are the performance values of the light and compact 7.5 kg TTR 57 E. With a dehumidification performance of up to 9 litres per day the it reduces the room's humidity to as low as 40 %, if required.
