Comfort dehumidifier TTR 50 E

Powerful permanent dehumidification at low ambient temperatures – up to 7.5 l/24 h dehumidification performance, energy-saving desiccation technology

Powerful dehumidification performance and comfort combined in perfect design

The compact and portable desiccant dehumidifier TTR 50 E is the ideal drying device for unheated environments such as basements, garages, conservatories, laundry rooms, garden houses, storage rooms as well as rooms with generally low room temperature. Wherever coldness and humidity become a problem, when there is a risk of mould formation or even health hazards, the powerful TTR 50 E with hygrostat-controlled automatic dehumidification quickly and reliably helps to achieve an optimum humidity level of 50 % or 60 %.

This way, the TTR 50 E permanently prevents problems with condensate, mould formation and musty smells in rooms of up to 18 m² or 45 m³. The drying device with integrated carrying handle, 2.5 litre water tank, washable air filter and connection option for a condensation hose is also recommended for efficient damage repair thanks to the adjustable permanent mode (continuous operation) after water damage (flood, inundation) or for creating a healthy room climate in living and business rooms.

Optimal for unheated and cold environments

Especially in cold areas, where conventional condensation dryers only provide an insufficient or uneconomic dehumidification performance, the TTR 50 E convinces even at low dew points and low temperatures up to 0 °C with a strong dehumidification performance of max. 7.5 litres/24h. At low temperatures, compressor-operated condensing dehumidifiers are susceptible to the formation of ice and need to have regular defrost phases. This noticeably increases the power consumption and also reduces the dehumidification performance. This is not the case when using the TTR 50 E. As there is no power-hungry compressor technology integrated in the drying unit, it dehumidifies in a pleasantly energy-efficient manner, without breaks and also without distracting noise.

Living comfort in its most beautiful shape

The modern TTR 50 E combines state-of-the-art comfort and design in its pure white plastic housing. Visually, the dehumidifier impresses with its rounded, unobtrusive design without corners and edges. The carrying handle integrated into the device perfectly picks up the round design again. A filling level indicator on the front clearly shows the water level in the 2.5-litre water tank. A flashing LED indicates when the water tank shall be emptied. The comfort features of the TTR 50 E are well-rounded with the three-speed selectable fan for air circulation in the entire room and an 8-hour timer for time-controlled switch-off.

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

Laundry-drying function

The convenient functions of the TTR 50 E at a glance

The user-friendly operation of the TTR 50 E is just as outstanding as its design. All settings can be made easily and conveniently at the touch of a button via the intuitive control panel with LED display on the top of the device. The current room humidity level is indicated.

  • Fully automatic permanent dehumidification – ideal for keeping basements, conservatories and garages permanently dry or for fast drying of damp walls and floors after water damage.
  • Hygrostat-controlled automatic dehumidification function with target value preselection (50 % or 60 %) – ideally suited for establishing a healthy room climate with an optimum humidity level.

Three-speed fan with on-demand swing function

Uniform dehumidification of the room requires good air circulation. With the three-speed fan (max. 126 m³/h), the room air circulation can be optimally adjusted to the room size. A on-demand swing function provides an optimal distribution of the air, even inside furniture and objects. 

Selectable ionisation

The ionisation function can be switched on which will result in the TTR 50 E to capture dirt particles even more effectively via the air filter. In the course of the ionisation process, negatively charged ions are released. Their static charge binds all animal hair, fluff and dust particles. As a result, these particles sink down to the ground where they will be immediately drawn in by the air current of the three-stage fan to be bound by the filter. This way, the room air is cleaned of coarser particles.

Connection for condensation drain hose

Save yourself the hassle of emptying the water tank! In order to continuously drain the condensation water, a pipe can be connected on the rear of the device. The water can thus be conveniently drained off into an existing drain.

8-hour timer – programmed for comfort and economy

To save unnecessary operating times and thus electricity costs, for example when drying laundry, the operating time of the dehumidifier can be preset to two, four or eight hours.

The desiccant dehumidifier TTR 50 E is the economical drying solution for unheated and cold environments.

The TTR 50 E combines reliable drying and plenty of comfort

TTR 50 E – properties & dimensions
Compact size. Despite its high dehumidification performance even at the lowest temperatures, the TTR 50 E requires just as much space in the room as a sheet of A4 paper thanks to desiccation technology. Compared to compressor dehumidifiers, the TTR 50 E desiccant dehumidifier is particularly energy-efficient.
TTR 50 E – neatly arranged control panel
Neatly arranged control panel. The modern control panel with LED display is simply beautiful and extremely user-friendly. All settings can be made in a matter of seconds at the touch of a button, such as the hygrostat-controlled automatic dehumidification function, continuous operation, swing function, selectable ionizer and the convenient timer function for automatic switch-off.
TTR 50 E – connection for condensation drain hose
Large water tank. The large 2.5 -litre water tank provides sufficient space for excess moisture. A filling level indicator makes it easier for you to empty the container in time. Thanks to the option to connect a drain hose for the condesate and the selectable permanent mode, the TTR 50 E can also be used for continuous drying.
TTR 50 E – ventilation & swing function
Air circulation that fills the room. An optionally selectable swing function ensures that the air in the room optimally circulates and all areas are dehumidified evenly.
TTR 50 E – ionization
The TTR 50 E directly improves the room climate in multiple ways. It ensures optimum humidity of 50 or 60 %. Fluff, dust and pet hair in the room air are bound by the selectable ionisation function and will be caught in the air filter. The result is pleasant and noticeably cleaner air.
TTR 50 E – room size
Highly effective even at low temperatures down to 0° degrees Celsius. The TTR 50 E is the optimal dehumidifier for unheated or cold rooms up to a size of 18 m² or 45 m³.
TTR 50 E – washable air filter
Integrated air filter. A washable air filter cleans the room air from dust, fluff and animal hair. Cleaning the filter under clear tap water is done in no time if required.
TTR 50 E – carrying handle
Convenient carrying handle. Take the control of the room climate into your own hands and position the TTR 50 E flexibly where humidity becomes a problem or affetcs well-being.

Optimal dehumidification – anywhere you need it

TTR 50 E – attic flat
