Design dehumidifier and air cleaner TTK 27 HEPA

The perfect combination for a healthy room climate: 12 l dehumidifier and HEPA air cleaner with 95 % efficiency to protect against mould, bacteria, viruses, dust, pollen and allergens

Cleverly combined: Dehumidifier and air cleaner with 95 % HEPA filtration

Enjoying indoor air. Making this and even more possible in an outstanding way – the multifunctional design dehumidifiers TTK 27 HEPA and TTK 64 HEPA. Equipped with even two technologies for permanently improving the air quality, the combination devices eliminate unhealthy humidity in living and business spaces, offices, shops, unheated conservatories, basements as well as garages. Moreover, the room air is cleaned in the integrated HEPA filter and 95 percent of pathogenic bacteria/viruses, mould spores, pollen, house dust, particulate matter, allergens and other pollutants are removed. A permanent protection of health for everyone in the room – a noticeable relief particularly for allergy sufferers and people with house dust allergies. The modern dehumidifiers are available in a rectilinear cuboid design with chamfered edges and a structured surface in two versions and device sizes.

Everything inside – for healthier room air and more quality of life

A hygrostat-controlled automatic dehumidification system with target values for the desired humidity level (30 % to 80 %), digital air quality sensors, four operating modes including night mode and two fan stages guarantee a reliable dehumidification and air purification process. For unattended continuous operation, the device with overflow protection is further equipped with a hose connection at the rear to permanently discharge the condensate extracted from the air via a hose. A practical feature is the front colour LED display which indicates the status of the room air quality in three colours (blue, green, red). The LED illuminated segment display keeps you informed about the current humidity with percent accuracy, the preset target humidity and the remaining operating hours (with activated 24-hour timer) for time-controlled switch-on or switch-off.

Seeing the room air with different eyes: Air quality sensors

We cannot tell from the room air whether it is too humid or contaminated with pathogens by simply looking at it. You might normally notice that mould spores or viruses are invisibly floating in the air when it is already too late.

The room dehumidifier TTK 27 HEPA notices what we don't. Its digital humidity sensors continuously measure the room humidity level. The front colour LED display for the current room humidity is particularly convenient:

  • Blue: Indicates that the humidity is too low/dry (below 50 %).
  • Green: Indicates an optimum humidity level (between 50 to 70 %).
  • Red: Indicates that the humidity is too high (above 70 %).

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.

Purified and dehumidified room air makes the difference

Each person needs between 10,000 and 20,000 litres of air per day for breathing in and out. If the air is too humid and contaminated with pollutant particles or pathogens, it puts our immune system to the test and – in the worst case – triggers respiratory diseases. Likewise, the furniture, inventory and even the building structure can be damaged if the humidity level is permanently too high (> 60 percent).

Combined protection against humidity and pathogens

Rely on the TTK 27 HEPA with highly effective HEPA air purification technology to protect your health and furnishing and to monitor the room air quality simply and conveniently. With its combined air purification and dehumidification technology, this multi-talent reliably prevents the formation of unhealthy mould cultures and associated moisture problems such as mould formation, mildew stains and dampness. Virus-carrying aerosols, viruses (for example SARS-CoV-2 and influenza viruses), bacteria, mould spores, particulate matter, house dust, animal hair and other airborne pathogens are removed from the room air in the dual filter system consisting of a prefilter and a highly efficient HEPA filter. Besides, the growth of dust mites and allergens is reduced. An all-round clean affair.

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.

Comprehensive solution for a healthy indoor climate

The visually appealing 2-in-1 dehumidifiers/air cleaners TTK 27 HEPA and TTK 64 HEPA have a comprehensive range of comfort features, a high level of user comfort and a pleasingly low noise level in common. Therefore, the air improvers are also recommended to be used in noise-sensitive environments.

Hygrostat-controlled automatic dehumidification: In hygrostat-controlled automatic dehumidification mode, the TTK 27 HEPA works continuously until the desired humidity value is reached. This value can be adjusted in increments of 5 % in a range between  30 % and 80 %. Then the compressor switches off automatically. When the target value is exceeded again, the device is automatically activated. This way, the TTK 27 HEPA always provides for an ideal room humidity level according to your needs.

Continuous operation: Condensed water on the walls, on glass surfaces or thermal bridges and insufficient ventilation at the same time are frequent causes for moisture damage. Moisture damage also occurs if water enters the basement from the outside through an insufficiently insulated wall or during floods and heavy rain fall. For keeping such environments permanently dry, the TTK 27 HEPA comes with a powerful continuous operation mode. If this operating mode is selected, the room air is permanently dehumidified at maximum power.

Night mode: Poor air quality caused by an excessive humidity level, unpleasant odours or stuffy air can basically make you lose your sleep. In night mode, the TTK 27 HEPA cleans and dehumidifies the air with a gentle airflow and a dimmed control panel. For a good night's sleep to recharge your batteries.

Laundry drying function: For air drying your laundry in a gentle way, we recommend the laundry drying mode. The laundry drying function (also referred to as clothes drying mode or SuperDry function) is comparable to traditional air drying outside. Dehumidifiers such as the TTK 27 HEPA offer the benefit of drying laundry as gently as in the nature outside.

24-hour timer: There are good reasons to switch the TTK 27 HEPA on or off after a preset number of hours. In the bedroom, we recommend a combined operation of dehumidification and purification to allow for a restful sleep. During the day, on the other hand, it is not necessary to keep the device running when you are out of the house. Similarly, dehumidification and purification of the air in the office or workplace are only necessary during working hours. For these and other applications, the TTK 27 HEPA is equipped with a programmable 24-hour timer. This allows you to preset the number of operating hours until automatic switch-on or switch-off in increments of 1 hour.

The living-space friendly design dehumidifier TTK 27 HEPA convinces by both its compelling appearance and also with regard to its technical features. The device regulates the room air humidity to a healthy level and, thanks to HEPA filtration, protects against viruses, bacteria, mould spores and other airborne pollutants.

Socket hygrostat BH30 with dehumidifier TTK 27 HEPA

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.
