Comfort dehumidifier TTK 122 E

Dehumidification performance of 40 l/24 h for a healthy room climate and fast drying after water damage – suitable for private and commercial use

Dehumidifies living spaces, dries basements and removes water damage

The comfort dehumidifier TTK 122 E protects and preserves what is dear to you – the health of your family and your own four walls. For children, the elderly and people with respiratory diseases, excessively humid room air is a constant burden. The building structure and inventory, too, suffer from excessive humidity after heavy rainfall, storms, floods or burst water pipes. The TTK 122 E with automatic hot gas defrost system provides a quick and lasting remedy here – for optimum drying results, even at low temperatures.

One for all: prevents mould, corrosion and structural damages

Excessive moisture in the room air (> 60 percent) provides a perfect hotbed for pathogens. Mould spores spread in the living spaces and increase the risk of catching a respiratory disease. Damp walls and floors after water damage also favour the formation of mould, which is hazardous to health. Similarly, vintage cars in the garage, works of art on the walls and archived documents and books also suffer from excessive humidity. The causes of harmful humidity are manifold: defects in the building's waterproofing, insufficient ventilation as well as storms, floods or leaks in water-bearing lines.

Compact design – outstanding dehumidification performance

Whether as a room climate improver in private surroundings or as a construction dryer for commercial use – the cuboid stainless steel dehumidifier TTK 122 E impresses with its convenient features (e.g. the 24h timer and auto restart function as well as the control panel lock function), an 8-litre condensation tank and a high dehumidification performance of 40 l/24 h at an air flow rate of 240 m³/h – enough to handle rooms sized up to 120 m² or 300 m³. The auto restart function (memory function) makes the device restart automatically with the previously selected settings after a brief power cut. Good to know: smaller rooms can be conveniently dehumidified with the structurally identical TTK 120 E with a dehumidification performance of 30 l/24 h and an air flow rate of 240 m³/h.

For maximum user comfort, the control panel is equipped with easy-to-clean membrane keys and a digital display indicating the room temperature and humidity. The target humidity can be selected in increments of 5 percent. Moreover, a filling level warning light to indicate a full water tank, an overflow protection with automatic switch-off function and a reusable air filter, which is easy to clean, also belong to the standard equipment of the electronically defrostable TTK 122 E.

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

Investment protection for your drying devices

Particularly during construction drying operations in summer or when drying water damages, it is very likely that climate conditions arise which may significantly shorten the lifetime of condenser dryers – regardless of the make. We as manufacturer care about the fact that for process-related reasons your condenser dryers often have to be replaced much too soon, hence we have prepared a valuable practical recommendation relating to the investment protection of your drying devices.

Technical construction drying

Did you know that every construction dryer is at the same time a commercial dehumidifier, but that not every commercial dehumidifier is automatically a real construction dryer? Here you can find out the reasons for this, and why hot gas defrosting makes the decisive difference ...

Environmentally friendly refrigerant R290

Propane (R290) as environmentally friendly refrigerant in dehumidifiers

Every year, several million tonnes of environmentally harmful CO2-emissions (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.

Proven drying technology for a healthy indoor climate and for drying damp masonry and floors

Thanks to its rust-proof stainless steel housing, bar handles on both sides and rubber-tyred easy-running wheels, the robust TTK 122 E withstands even the harshest of conditions at its place of use.

A dehumidifier for all occasions:

  • Optimally suited for a healthy indoor climate in living spaces
  • Protection against moisture in archives, libraries and art exhibitions
  • Protection against corrosion and mould in (vintage car) garages, basements and storage rooms
  • Construction site drying and drying of damp masonry after water damage

Connection for external condensate drain

For applications where regular draining of the 8-litre condensation tank is either not possible or undesirable, e.g. for unattended permanent drying in basements, garages, holiday homes or on boats, the TTK 122 E comes equipped with an integrated hose connection for direct discharge of the condensate into a drain. The hose required for this is already included in the standard scope of delivery.

Automatic hot gas defrosting for faster drying results

At low temperatures (below 12 °C), the integrated automatic hot gas defrost system ensures continued reliable dehumidification – without long defrost phases. In contrast to time-consuming air circulation defrosting used in normal condenser dryers, the TTK 122 E is defrosted by introducing hot gas into the evaporator. This helps to reduce the defrosting time considerably and to reach the drying target more quickly.

SuperDry function for an accelerated drying of textiles

A convenient feature for quickly dehumidifying wet laundry, clothes or carpets is the special SuperDry function. This way, even large textiles that do not fit in the tumble dryer can be dried in a very short time.

With the comfort dehumidifier TTK 122 E you are perfectly equipped for almost all drying and dehumidification tasks in private and commercial surroundings – recommended for rooms sized up to 120 m² or 300 m³.

Socket hygrostat BH30 with dehumidifier TTK 122 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.

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.
