Main highlights

This makes this possible an optimally coordinated interplay of high-performance heat transfer and blower system, which can circulate and dehumidify air volumes of 925 m³/h.
The rolling piston compressor technology of the TTK 655 S not only allows transport in virtually any position, but also a time-saving, immediate commissioning of this dehumidifier immediately after installation.
The powerful 1.9 kW compressor guarantees high dehumidification capacity in large rooms even at low room temperatures below 10 °C – and the high-quality hot gas defrosting system of the TTK 655 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 TTK 655 S can condense up to 100 litres per day.
Thanks to the ergonomic design in trolley design with handle bar and large wheels, the transport itself is convincingly fast even over rough terrain or stairs.
Standard at Trotec, but not everywhere of course. The top model of our standard commercial air dehumidifier series defines itself as superlative in every respect:
And indoors, the non-staining rubber wheels of the TTK 655 S leave no marks on parquet or other sensitive surfaces.

Main highlights

The commercial dehumidifier TTK 350 S ensures optimal indoor climate, e.g. in warehouses, thanks to its hygrostat-controlled automatic operation. The target can be set from a minimum value to the maximum value via a rotary switch.
The TTK 350 S is also a good choice for use in water damage remediation. The drying of the premises can be greatly accelerated in such damage cases and thus reduces mould formation by a lot.
The TTK 350 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 350 S automatically performs self-de-icing if required.
The TTK 350 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 350 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 powerful and comfortable commercial dehumidifier TTK 350 S, shell buildings can be dried optimally and easily in no time at all. Thus, larger delays are excluded due to necessary drying processes in the construction project, even at low temperatures.
In permanent mode, the TTK 350 S dehumidifies the room air in continuous operation. Therefore, it is ideal for longer unattended dry maintenance tasks and professional construction drying applications. The condensate generated during dehumidification should be removed via the connectable drain hose, so that you do not have to constantly empty the water tank.

Main highlights

With the TTK 170 ECO, the name comes with it: its low price impresses as well as the high dehumidification performance, and this attractive price-performance ratio makes the TTK 170 ECO the first choice for all commercial users looking for a particularly robust and economical dehumidifier.
Thanks to the professional automatic hot gas system, the TTK 170 ECO achieves high dehumidification values even at low temperatures in unheated rooms or on cool construction sites.
Thanks to an external condensate drain and optionally available condensate pump, the TTK 170 ECO is also ideal for longer unattended dry-keeping operations, whose duration can be accurately determined with the integrated operating hour counter - ideal especially for commercial applications. In addition, this dehumidifier also has a connection for an optional hygrostat for moisture-dependent drying control.
Additional transport safety is provided by the practical cable receivers on the back of the device - and because the TTK 170 ECO is equipped with an efficient roller piston compressor, the maintenance-friendly device can be transported and stored in any position.
A frequent change from one construction site to another or use in rough environments and difficult terrain is no problem for this condenser dryer: the robust steel construction in trolley design with transport handle and large wheels can be easily driven to any location.

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.
