Dehumidifier and air cleaner TTK 99 HEPA

The most powerful in its class: 31 l dehumidifier + HEPA air cleaner with 95 % efficiency to protect against mould, bacteria, viruses, dust, pollen and allergens

Maximum dehumidification and drying with 95 % HEPA air purification

If moisture becomes a health issue in your private living environment, your garage or at your workplace, the dehumidifier TTK 99 HEPA reliably and permanently provides for a healthy room climate. Thanks to its high dehumidification performance of 31 litres/day, which is unchallenged in its device class, the mobile dehumidifier is perfect for room sizes up to 90 m² or 230 m³. Even drying moist masonry, for example after heavy rainfall or floods is a task mastered easily by the compact power pack with its strong air performance of 170 m³/h – making it a match for conventional construction dryers. With its modern design, a black, set-off control panel as well as handles embedded in the housing to allow for a quick change of location, the TTK 99 HEPA is optically appealing.

Outstanding design, impressive dehumidification performance

The inner values of the TTK 99 HEPA which combines two technologies in one to improve the room air are just as unique as its product design. In the dehumidification mode, the 2-in-1 dehumidifier regulates the air humidity to the level you desire, offering a user-definable target value in the range of 30 % to 80 %. Moreover, the air is cleaned in the dual filter system, which consists of a prefilter and a HEPA filter, and 95 percent of pathogens such as viruses, bacteria and mould spores as well as pollen, house dust/particulate matter, allergens and other airborne pollutants are removed.

A vital contribution for a healthier life and healthier working – a noticeable relief particularly for allergy sufferers and people with house dust allergies.

A powerful ally when humidity becomes an issue. The TTK 99 HEPA dehumidifies:

  • Living spaces
  • Shops
  • Damp garages
  • Office environments
  • Conservatories.
  • Archives
  • Storage facilities
  • Sports/fitness rooms
  • Laboratories
  • Holiday homes
  • Wet basements
  • Changing rooms

The hygrostat-controlled automatic dehumidification function with target value preselection of the humidity level (30 % to 80 %), digital air quality sensors, four operating modes including a laundry drying function and permanent operation, a silent night mode as well as a two-stage fan guarantee reliable dehumidification and cleaning of the room air. An overflow protection ensures that the device switches off when the max. filling level of the 4 litre water tank is reached. The hose connection offers an even more enhanced level of comfort to discharge the condensate conveniently via the hose that is already included in the scope of delivery. A practical feature is the modern 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 99 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

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.

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 99 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.

A leader in terms of performance and equipment

All dehumidifiers of the TTK series convince with an excellent comfort equipment, a high level of operational comfort as well as a remarkably low noise emission, making the mobile air fresheners also perfect for the use in noise-sensitive environments (bedrooms, children's rooms, office environments).

Continuous operation: Condensation on the windows and walls, thermal bridges, or an insufficient ventilation system are frequent reasons for moisture issues, but also if groundwater/rainwater penetrates the basement in the case of flood or heavy rainfall. To ensure quick dehumidification of such environments, the TTK 99 HEPA is provided with a powerful permanent mode with a max. dehumidification performance of 31 litres/day. If the permanent mode is selected, the room air is permanently dehumidified at maximum power.

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 99 HEPA offer the benefit of drying laundry as gently as in the nature outside.

Night mode: Stuffy air can literally deprive you of your sleep. In addition to the moisture emitted by breathing, sweating also increases the humidity to an unhealthy level. In the night mode with a dimmed control panel, the TTK 99 HEPA regulates the humidity level with a gentle airflow and a low noise emission.

Child lock: In order to protect the device settings against curious child's hands, the control panel can be locked with the practical child lock function.

24-hour timer: There are good reasons to switch the TTK 99 HEPA on or off in a time-controlled fashion. In the bedroom and in the children's room, we recommend the combined operation of dehumidification and purification to allow for a restful sleep. During the day, on the other hand, dehumidification is rarely necessary when the family is out of the house. Similarly, dehumidification and purification of the air at the workplace are only necessary during working hours. To adapt the dehumidification time to your individual rhythm of life, the TTK 99 HEPA comes equipped with an integrated programmable 24-hour timer, allowing you to preset the operating time until automatic switch-on or switch-off in increments of 1 hour.

The dehumidifier TTK 99 HEPA inspires design enthusiasts. The device regulates the room air humidity to a healthy level and, thanks to the integrated HEPA air purification feature, protects against viruses, bacteria, mould spores and other airborne pollutants.

Socket hygrostat BH30 with dehumidifier TTK 99 E

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.
