Comfort dehumidifier TTK 54 E

The elegant solution for the use at home and in the office

Comfort, design and a high air flow rate

You will hardly find a similarly successful implementation of pure design as with the TTK 54 E. Elegantly rounded edges harmonize with an elegant white, and the discreet recessed handles point the way to the practical equipment details of this flagship dehumidifier.

With its manifold features, the TTK 54 E is entirely trimmed for high performance. This is, for example, reflected by its four operating modes: Here, the dehumidifier offers hygrostat-controlled automatic dehumidification with target values that can be set from 35 to 85 % relative humidity in convenient steps of 5 % – including an on-demand turbo blower!

A popular alternative to the automatic dehumidification function is the comfort function of the TTK 54 E, which automatically controls the humidity level to a comfortable value depending on the temperature. Further operating modes available are the laundry drying function and the continuous operation function.

Comfort function: Temperature-dependent dehumidification

For a perfect indoor climate, the room temperature and humidity level must be synchronized. And this is exactly where the temperature-dependent dehumidification comes in. The device adjusts the humidity level to the optimum value depending on the temperature. The comfort function is particularly advisable when utilizing program-controlled heating systems. If the room temperature changes in the day or night, the dehumidifier adapts its dehumidification performance in a fully automated fashion.

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

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. 

Useful features

When it come to its dehumidification performance, the TTK 54 E is at its most impressive. Accumulating up to 18 litres of condensate in 24 hours, the device is a truly reliable partner in keeping living spaces and offices sized up to approx. 40 m² dry.
Another special feature of this excellent dehumidifier is the window that allows for a visual check of the water tank's filling level. Naturally, the remaining equipment features of this dehumidifier also meet the high standards of the HomeComfort series. These features include a practical timer function, a filling level warning light to indicate a full water tank and an overflow protection with automatic switch-off.

The variety of functions is completed by the washable air filter and the integrated drainage connection allowing for unattended continuous operation. The convenient cable holder, the integrated carrying handles and the steerable wheels turn any change of location into a simple exercise.

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.

TTK 54 E – special equipment features

TTK 54 E control panel
The operating panel of the TTK 54 E is provided with a clear design and is easy to understand. The digital display for example shows you the current relative humidity level in the room.
TTK 54 E air filter
The easily removable air filter retains lint and animal hair and can be quickly and easily wiped or washed out.
TTK 54 E water tank
The removable water tank is provided with a storage capacity of 3 litres and a fill level window. The device stops automatically when the tank is full and indicates this via LED.
TTK 54 E rear view
In order to continuously drain the condensation water, a pipe can be connected on the rear of the device. The power cable can be wound up properly and clamped in the mounting bracket.
TTK 54 E comfort function
By the automatic coordination of room temperature and air humidity, the comfort function provides for a perfect feel-good ambience. Depending on the temperature prevailing in the room in each case, the humidity level is regulated automatically to a specially pleasant 45%, 50% or 55%.
TTK 54 E timer function
Use the practical timer function to switch the device after a defined number of hours (up to maximally 24 h) on or off. The timer can be programmed in increments of 0.5 hours (0 to 10 h) or in increments of 1 hour (10 to 24 h). The timer prevents unnecessary operating periods and allows you to adapt the dehumidification to your individual rhythm of life.
TTK 54 E laundry drying function
The TTK 54 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 54 E permanent mode
In the permanent mode, the TTK 54 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.

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.
