Comfort dehumidifier TTK 28 E
Top drying power for small rooms
Space-saving design, easy handling
and convincing functions
Small enough to fit in everywhere. Light enough to be applied flexibly. Perfectly equipped to master every challenge. The TTK 28 E was designed specifically for small, heated rooms – and impresses with a high performance.
Thanks to the compact dimensions of the dehumidifier TTK 28 E, you will always find a place where the TTK 28 E can do its job, even in the smallest room. It can, for example, keep living spaces and offices sized up to 15 m² dry reliably – with a daily dehumidification performance of up to 10 litres.
A porthole allows for a clear view into the water tank to keep a constant eye on the filling level. Naturally, a filling level warning light warns of a full water tank and the overflow protection with automatic switch-off guarantees an immediate stop of operation.
Effective and simple
Needless to say, the device also comes with a function for hygrostat-controlled automatic dehumidification. First, a fixed humidity value is selected by means of the target value preselection function. The setting range is between a relative humidity level of 40 % and 60 % in increments of 10 %. When this value is exceeded, the dehumidifier automatically switches itself on and then off again to save energy as soon as the desired target value has been reached.
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
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.
Small in size, impressively high performance
The TTK 28 E offers convenient features such as the washable air filter. A cable and plug holder, the retractable, convenient carrying handle as well as the steerable wheels facilitate any change of location from one room to another. All functions can be adjusted quickly and easily on the clearly structured and intuitive control panel.
As a matter of course, it is also possible to have the TTK 28 E operate continuously whilst unattended, thanks to the integrated drainage connection – the ideal solution for continuous operation in hobby rooms or holiday homes, where one cannot always empty the tank.
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.
