Wheel it in and watch it work

The TTK 175 S impresses with a variety of detailed solutions which save you time, enhance your performance and secure value retention – attractively combined in the tried and tested German industrial design – protected prototype.

All electrical components are also protected from dust and dampness by default. The special enclosure offers maximum protection of the electronic equipment from anything dangerous which may enter and impair the functionality and durability. This enclosure predestines the commercial dehumidifier for rough environments at various sites.

Furthermore, compared with other defrost systems, the high-quality hot gas automatic defrost of the TTK 175 S guarantees a much more efficient dehumidification performance without defrost pauses on a time interval during which no dehumidification occurs!

Powerful rotary compressor technology in a robust carriage design

Thanks to the ergonomic construction and carriage design with a bar handle and large wheels, the TTK 175 S can easily be transported in construction site conditions or up and down stairs. The non-marking rubber wheels leave no marks on your floorboards or other sensitive flooring indoors.

The rotary compressor of the TTK 175 S not only makes it possible to transport it just about anywhere, it also allows you to start the dehumidifier immediately after positioning.

Once it is in position, this powerful condenser dryer immediately shows what it is capable of.The TTK 175 S' high-quality 0.88 kW rotation compressor is able to offer drying capacities of up to 50 litres per day and impresses even at low ambient temperatures with its high dehumidification performance.

Two stacking grooves make it possible to stably stack equally sized TTK S commercial dehumidifiers to save space.

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 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.

The central equipment features of the TTK 175 S at a glance

The TTK 175 S ensures automatically that the target value entry is kept constant. When this value is exceeded, the device switches off automatically and also switches on again automatically when the value falls below the target entry. The target value preselection is between 50 % and 90 %, depending on the air humidity value in the room which is to be reached.
TTK 175 S – automatic mode
The TTK 175 S comes with function for automatic defrosting. When the room temperature is below 11 °C, the evaporator would freeze during dehumidification. This is why the TTK 175 S carries out fully automatic self-defrosting, if required.
TTK 175 S – automatic defrosting
The TTK 175 S has a memory function. Thanks to this, the device restarts after an unexpected shutdown due to a power interruption with the preselected setting as soon as the power supply is available again.
TTK 175 S - memory function
In order to continuously drain the condensation water, a pipe can be connected on the rear of the device. This is especially suitable for cellar or storage spaces which are subjected to mould formation by excess humidity.
TTK 175 S – permanent mode
The TTK 175 S commercial dehumidifier ensures an optimal room climate, e.g. B. in warehouses, through its hygrostat-controlled automatic operation. The target can be set using a rotary switch from a minimum value to a maximum value.
TTK 175 S - warehouse
Shells can be dried perfectly and easily in no time with the powerful and comfortable commercial dehumidifier TTK 175 S. This prevents major delays caused by necessary drying processes in the construction project, even at low temperatures.
TTK 175 S – shell
The TTK 175 S is also an excellent choice when it comes to its use for water damage restoration. The process of drying the spaces can be substantially accelerated in such cases of damage, as a consequence considerably reducing mould formation.

Plug-in installation condensate pump available as accessory

Accessory tip:

Installation condensate pump for continuous operation

Suitable for all TTK-S models, a plug-in condensate pump is also optionally available, which can be installed very easily instead of the collection container and allows for automatic condensate discharge via the 5-m drain hose supplied. With a pump performance up to a distance of 50 m and a maximum delivery head of 4.3 metres, this pump is ideally suitable for longer unattended dry keeping applications in continuous operation – just add it to your order right away!

Proper energy billing for existing equipment without meters?

You're using this or another electrical appliance without MID-compliant energy consumption meter of which you have to report the current consumption to insurance companies? Then the BX50 MID is the perfect solution. Just install it between the device and a fixed socket – done!

Fan assistance for construction drying

Fan assistance

Quicker construction drying by air circulation

The drying time can be reduced by half if construction dryers and fans are combined. In doing this, each dryer is supplemented with a fan, which significantly improves the drying performance and thus also the duration of the drying process.

The increased air circulation results in a quicker evaporation of the humidity, for the higher the flow rate at the material surface, the sooner will the drying process be completed.
The axial fans of the TTV series and TTV-S series are especially suitable to provide assistance with regard to the drying process.

Protective hood

A handy protective cover is optionally available for all commercial dehumidifiers of the TTK-S series.
