Comfort dehumidifier TTK 68 E

Trendy technology with a smart look

High performance combined with design and comfort

The TTK 68 E with its elegant green metallic look evidently focuses not only on design, upon first switch-on this comfort dehumidifier this comfort device also demonstrates that a full range of de luxe features can be affordable for everyone.

One of many sophisticated extras: The air flap opens automatically when pressing the start button and closes upon switch-off in order to protect the air outlet from dirt. The device can be used in continuous operation, employing a hygrostat automatism or else whilst controlled by a timer switch. It comes with an extra mode for drying laundry and automatically indicates the necessity of filter cleaning or of emptying the condensation tank.

The target humidity value is entered conveniently via real-value selection and shown directly on the innovative integral display, which is not only a true eyecatcher, but owing to this construction also particularly easy to clean.

Healthy feel-good climate

Using the TTK 68 E of the HomeComfort series you can ensure the optimum humidity level and a healthy feel-good climate in your own four walls throughout the year. Not only the right temperature is decisive for an ideal room climate, but also an optimum humidity level. In heated living spaces, the relative humidity level should not exceed a threshold of 60 %, whereas in bathrooms it may rise to 70 % or more.


Moisture in the bathroom, basement or bedroom can lead to mold. All relevant information about our comfort dehumidifiers can also be found in the product brochure. Download the PDF directly here.

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.

Convincing features

The timer function, a filling level warning light that indicates a full water tank, the overflow protection with automatic switch-off, a laundry drying mode as well as a child lock top off the comfort equipment of the TTK 68 E. Moreover, the built-in, washable air filter also enables air purification by removing dust and animal hair.

An integrated separate hose connection allows for external condensation draining also in the unattended permanent mode – the ideal solution for continuous operation in hobby rooms or holiday homes, where one cannot always empty the tank. The large condensation tank has a capacity of 4 litres, which conveniently reduces the draining frequency. Thanks to its wheels and the convenient handles, the TTK 68 E is also ideally prepared for flexible site changes. Owing to its convenient features handling the TTK 68 E is as easy as winking.

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 68 E – special equipment features

TTK 68 E control panel
The control panel of the TTK 68 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 68 E air filter
The easily removable air filter retains lint and animal hair and can be quickly and easily wiped or washed out. In addition, the TTK 68 E comes with a special filter cleaning indication.
TTK 68 E water tank
The removable water tank has a storage capacity of 4 litres. The device stops automatically when the tank is full and indicates this via LED.
TTK 68 E – drainage connection
In order to continuously drain the condensation water, a pipe can be connected to the side of the device.
TTK 68 E comfort function
The TTK 68 E is equipped with a hygrostat-controlled dehumidification function with real-value humidity selection. Using the innovative integral display, the desired humidity value can be set to target values between 30 and 80 % RH in increments of 10 %. Once the desired humidity value has been reached, the compressor will switch off automatically. If the value is exceeded, the device is automatically activated.
TTK 68 E timer function
Use the practical timer function to switch the device on after a defined number of hours (up to maximally 24 h). The use of the timer prevents unnecessary operating periods and allows you to adapt the dehumidification to your individual rhythm of life.
TTK 68 E - laundry drying function
The TTK 68 E may also be used as a 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 68 E – permanent mode
In the permanent mode, the TTK 68 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 68 E – for working from home
In order to prevent the formation of unwelcome mould that is dangerous to your health in cellars, hobby rooms or on cool corners and walls exposed to dampness in the first place, we recommend using a dehumidifier continuously and right from the start.
TTK 68 E – at home
Whether it is used in the office, in the studio or in the living room – with its hygrostat-controlled automatic dehumidification with real-value humidity selection, optionally fully automatic or permanent operation and timer function, the dehumidifier TTK 68 E provides for a perfect room climate at all times.
