Main highlights

The power switch is protected by a protective cap against dust and splashes of water. The slotted hygrostat rotary switch protects against accidental adjustment of the switch position.
The TTK 650 S has an automatic de-icing function. Once the room temperature is less than 11°C, the evaporator would freeze when dehumidified. Therefore, the TTK 650 S automatically performs self-de-icing if required.
The TTK 650 S has a memory function. Thanks to this, the device will restart after an unexpected shutdown due to a power interruption with the preselected setting as soon as the power supply is available again.
The TTK 650 S automatically ensures that the target value input is kept constant. If exceeded, the device switches off automatically and automatically switches on again when it falls undershot. The target value pre-selection is between 32% and 100%, depending on which humidity value in the room should be achieved.
Thanks to the standard external condensate drain, the TTK 650 S is ideal for longer and unattended continuous drying applications.
In permanent mode, the TTK 650 S dehumidifies the room air in continuous operation. Therefore, it is ideal for longer unattended dry maintenance tasks and professional construction drying applications.
Despite its compact dimensions, the TTK 650 S shines with a dehumidification capacity of 100 l/24h for rooms up to 590 m² or 1470 m³. Its trolley design made of robust metal housing can be transported and stored in any position thanks to the roller piston compressor.

Main highlights

This is made possible by the clever combination of a powerful 1.27 kW rotary piston compressor and a quality fan for air volumes up to 1,000 m³/h.
The high-quality hot gas defrosting mechanism of the TTK 355 5 S ensures a much more efficient dehumidification performance compared to other defrosting devices without time interval-related defrosting breaks in which no dehumidification takes place.
The exterior of this construction dryer is in no way inferior to its convincing inner values: all components of the TTK 355 S are reliably protected and attractively housed in a practice-optimised German industrial design, which is protected as a design.
Thanks to the high air circulation, the performance-optimised heat transfer system can permanently supply extremely much moisture from the ambient air for quick drying. Up to 70 litres of moisture can be removed from the room air with just one TTK 355 S per day.
Thanks to the ergonomic trolley design with handle bar and large wheels, the TTK 355 S can be easily transported even over rough terrain or stairs - the roller piston compressor technology allows transport in virtually any position. And indoors, the non-staining rubber wheels leave no marks on parquet or other sensitive surfaces.
Reduce high humidity values in best time or keep large rooms dry – here the TTK 355 S is in its area, that's what it was designed for.
Even in the warehouse, the TTK 355 S looks good - and itself amazingly small. Because it has two practical stacking grooves on the top of the device, which allow stable and space-saving stacking of dimensionally identical TTK-S devices during transport and in the depot.
A special encapsulation protects the electrical components of the dehumidifier from harmful dust or moisture retention, which can affect the function and longevity of the electronics.

Main highlights

The solid workmanship is not at the expense of ease of use, on the contrary – the control panel of the TTK 122 E, equipped with easy-care membrane buttons, allows for example the direct input of the desired humidity value via the digital display. An energy-saving practical advantage compared to analogue controlled dehumidifiers with only unitless rotary switch preselection.
The TTK 122 E is equipped with a high-quality hot gas defrosting system, which ensures a much more efficient dehumidification performance compared to electronic defrosting devices, especially at low ambient temperatures without time interval-related defrosting breaks in which no dehumidification takes place. This condenser dryer is therefore also suitable for dehumidifying and keeping unheated cellar or storage rooms.
Its robust stainless steel housing withstands even the most adverse environments. Optimal requirements, for example, for frequently changing applications on construction sites or in water damage drying out. The TTK 122 E is easy to transport thanks to the rubber-tyres steering wheels and handle on both sides.
For applications where regular emptying of the 10 litre water container should not be possible, for example when unattended continuous drying in weekend houses or on boats, the TTK 122 E has an integrated hose connection for direct drainage of the condensate into a drain. The hose required for this purpose is already included in the standard delivery.
During operation, the current values of the air temperature and humidity prevailing in the room can also be displayed on the display of the TTK 122 E for climate control.
