Comfort dehumidifier TTR 57 E
Easily keep an eye on the humidity level – even in unheated 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.
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.
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.
Auto restart function
In case of an unexpected switch-off due to a power interruption, the auto restart function (or “Memory function”) makes the device restart with the previously selected setting as soon as the power supply has been restored. This makes the dehumidifier also suitable for combined use with a timer.
Gentle laundry drying with dehumidifiers
Apart from ambient air dehumidification, a dehumidifier can be conveniently used for drying laundry – either in an assisting way or as a full replacement for a conventional dryer. The laundry drying function (also referred to as clothes drying mode or SuperDry function) is comparable to traditional air drying outside.
Dehumidifiers offer the benefit of drying the laundry as gently as in the nature outside. Colours retain their brilliance and the life span of clothes is longer than with conventional dryers – and all this with a substantially lower power consumption.
Furthermore, even sensitive materials such as wool, silk or synthetic fibres can be dried without any problems. In contrast to pure air drying, the laundry feels much softer and more pleasant on your skin.
Laundry drying can also be performed with dehumidifiers without an additional laundry drying function. The target value of the air humidity must then be set in accordance with the desired residual humidity:
Cupboard dry: 46 % of relative air humidity
Iron dry: 58 % of relative air humidity
Skin dry: 65 % of relative air humidity
The convenient functions of the TTR 57 E at a glance
- Target value preselection:
Set your desired humidity value of 40 %, 50 %, 60 % or 70 %. - Continuous operation:
In continuous operation mode the device dehumidifies continually at its maximum performance. - Function for drying laundry:
Using the device as room air and laundry dryer you can select the following settings: cupboard dry (46 % RH), iron dry (58 % RH) or pre-dried (65 % RH). - Ventilation operation:
You can choose from 3 fan stages for drying room air circulation. - 24-hour timer:
Programme the desired switch-on or switch-off time.
Furthermore, the TTR 57 E is equipped with a filling level warning light indicating a full condensation tank, a connection for external condensation draining as well as washable activated carbon and air filters for the filtration of dust and animal hair.
The TTR 57 E combines reliable drying and plenty of comfort

Benefit from the Trotec brand quality guaranteeing high value, safety and functionality. Via the registered GS mark the inspection authority Intertek certifies that, if used foreseeably and as intended, the device does not pose a risk to the health and safety of the user.
Save electricity and money on dehumidification
With our socket hygrostat BH30 you can additionally save money when dehumidifying damp rooms or keeping rooms dry. The programmable switch is simply plugged in between the dehumidifier and socket to regulate the dehumidification process based on the measured humidity level.
Once the desired target humidity is reached, the hygrostat disconnects the device from the mains until dehumidification is required again. By switching off the compressor and fan during standby times, the device's energy consumption is noticeably reduced.
The initial acquisition costs of the BH30 will have been amortized in a minimum of time.
Moreover, many dehumidifiers only offer rough target value setting for optimum humidity. The hygrostat BH30 allows the room humidity level to be adjusted in increments of 1 % from 20 % to 90 % and thus offers significantly more precise target humidity selection.
Our recommendation for climate control:
The room thermohygrometer BZ05
Simultaneous display of room temperature, humidity level and time or date as well as an additional feel-good indication.
The design weather station BZ06
Simultaneous indication of room temperature, humidity level, date, time, weekday and symbolic weather forecast. Supplies helpful information for preventing mould growth.
