Comfort dehumidifier TTK 100 E

Powerful dehumidifier with a dehumidification performance of 30 litres in 24 hours for rooms with a size of up to 90 m²

Professional dehumidifier
which can compete with the great ones of its class when it comes to its performance

In the TTK 100 E you have a trendy dehumidifier combining a successful design with advanced operating elements. 

Unlike dehumidifiers with analogous controllers for the preselection of minimum and maximum operation regardless of the unit, with the TTK 100 E you can directly enter the desired humidity value via the digital display. An integrated hygrostat implements this target fully automatic and adjusts the performance of compressor and two-staged fan.

The digital display on the clearly arranged and intuitive control panel for example shows you the current relative humidity level in the room as well as the current room temperature and the target value entered- Furthermore the device comes with a timer function, an automatic fault diagnosis system and a memory function. The integrated memory function ensures that the set humidity value and the selected operating mode are still saved after switch-off. The laundry drying function tops off the range of functions of the convenient dehumidifier. The integrated separate hose connection enables external condensation draining even in unattended continuous operation – the ideal prerequisite for continuous operation in hobby rooms or holiday homes.

Auto restart function

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

Laundry-drying function
Environmentally friendly refrigerant R290

Propane (R290) as environmentally friendly refrigerant in dehumidifiers

Every year, several million tonnes of environmentally harmful CO2emissions (greenhouse gases) are emitted into the air by synthetic refrigerants. For this reason, the utilization of alternative refrigerants has become one of our key objectives. By using propane (R290) as refrigerant, this dehumidifier makes a valuable contribution to protecting our climate.

The natural refrigerant propane (R290) is an organic compound belonging to the group of hydrocarbons. Unlike synthetic refrigerants the environmentally friendly propane (R290) comes with neither ozone depletion potential (ODP = 0) nor a noteworthy greenhouse effect (GWP = 3).

Additional bonus for the environment: Owing to its excellent thermodynamic properties, propane (R290) is a particularly energy-efficient refrigerant thereby additionally reducing your energy costs.

Convenient adjustment of the desired humidity level

TTK 100 E display in the detail

Indicated on the display of the TTK 100 E, in addition to the preselected room humidity value (1), are the current values of the air temperature (2) and humidity in the room (3). 

If required, this comfort dehumidifier can also be controlled by the integrated timer (4) or else used in continuous operation.

TTK 100 E – special equipment features

TTK 100 E - control panel
The control panel of the TTK 100 E is provided with a clear design and is easy to understand. The digital display for example shows you the room temperature and the current relative humidity level in the room.
TTK 100 E – air filter
The easily removable air filter retains lint and animal hair and can be quickly and easily wiped or washed out.
TTK 100 E – water tank
The removable water tank has a storage capacity of 4.3 litres. The device stops automatically when the condensation tank is full or not installed correctly and indicates this in the display.
TTK 100 E - condensate draining connection
In order to continuously drain the condensation water, a pipe can be connected at the side of the device. Use a suitable tool to remove the cover from the connection.
TTK 100 E – automatic operation
The TTK 100 E ensures automatically that the target value entry is kept constant. When this value is exceeded, the device switches off automatically and also switches on again automatically when the value falls below the target entry. The target value preselection is between 30 and 80 %. In order to attain an optimum feel-good climate, the target value should be set between 50 and 60 %.
TTK 100 E timer function
Use the practical timer function to switch the device on or off after a defined number of hours (1 to 12 h). The timer prevents unnecessary operating periods and allows you to adapt the dehumidification to your individual rhythm of life.
TTK 100 E laundry drying function
The TTK 100 E may also be used as room air laundry dryer to dry wet laundry in living spaces or utility rooms. In this way, you speed up the drying process of the clothes and prevent the humidity contained on the clothes from condensing in the room and from becoming a hotbed for mould.
TTK 100 E – permanent mode
In the permanent mode, the TTK 100 E dehumidifies the room air in continuous operation. This is especially suitable for cellar or storage spaces which are subjected to mould formation by excess humidity. To avoid that you constantly have to drain the water tank, a condensate drain hose can be connected.

TTK 100 E in the office
In order to prevent the formation of unwelcome mould that is dangerous to your health in offices, hobby rooms or on cool corners and walls exposed to dampness in the first place, we recommend to use a dehumidifier continuously in due time.
TTK 100 E in the living room
Whether at home, in the office or in the bedroom – with its automatic control of the entered air humidity value, indication of the relative humidity level, its laundry drying and timer function, the dehumidifier TTK 100 E provides for a perfect indoor climate at all times.

Hot gas defrosting

Dehumidifiers that are designed to be used in cooler rooms are equipped with a hot gas defrost system based on the bypass procedure instead of an air circulation defrost system.

Here, the hot refrigerant gas of the compression circuit is used actively for fast and effective defrosting. As soon as ice starts to form, a special solenoid valves opens automatically and redirects the hot gas from the compressor directly to the evaporator (instead of to the condenser) via a bypass. The valve closes again after defrosting is completed so that dehumidification operation can be continued via the regular refrigerant circuit.

Unlike air circulation defrosting, hot gas automatic defrosting allows for drastically shorter defrost phases of only a few minutes, which is an essential requirement for effective dehumidification in low-temperature surroundings such as unheated rooms. After all, the actual dehumidification process only takes place when defrosting is not in progress!

For the dehumidification of unheated rooms at temperatures that can sometimes be below 15 °C, dehumidifiers with hot gas automatic are therefore always better suited and more efficient than devices with air circulation defrost function despite identical compressor performance.

At temperatures of more than 15 °C, however, the capacity of these two dehumidifier types is increasingly assimilating until being virtually identical above temperatures of approx. 18 °C.

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.
