TTK 170 S Construction Dehumidifier - TROTEC

Powerful technology for workshops, warehouses and construction sites

The TTK 170 S is a mobile single-phase electric hot gas dehumidifier, designed to meet all your professional dehumidification needs.

The universal multi-talent

Whether you need to deal with the consequences of water damage, dry new buildings, or ensure continuous dehumidification in heated or unheated warehouses or offices, this versatile device offers an economical solution without compromising on quality and reliability.

Despite a price comparable to Far Eastern products, this model incorporates proven brand technology from traditional European manufacturing. Its simplified maintenance and reduced upkeep make it a particularly attractive investment.

Remarkable performance

Equipped with a professional automatic hot gas defrost system, the TTK 170 S treats surfaces up to 180 m² with a capacity of 50 liters per day. Regulation is carried out via a precise hygrostat allowing you to set a target relative humidity between 32% and 100% RH.

Its powerful airflow of 580 m³/h ensures effective circulation. The trolley structure combined with large wheels facilitates movement between different intervention sites.

Permanent mode for building drying

Connecting an external drain for condensation water — with the possibility of adding an external water pump as an option — makes this device particularly suitable for long-term interventions without supervision on construction sites.

Safety and robustness

  • The power switch and fill indicator are protected against dust and splashes by a dedicated cover
  • The hygrostat rotary switch is secured against accidental movement
  • The fill indicator lights up as soon as the tank is full
  • Automatic shut-off when the tank is saturated

  • The automatic hot gas defrost ensures effective dehumidification even at low temperatures. The standard external drain allows permanent use without supervision, ideal for construction sites and prolonged drying operations.

    Advantages of the TTK 170 S:

  • High dehumidification capacity, even at low temperature
  • Robust metal housing with plastic coating
  • Transport and storage possible in all positions thanks to the rotary piston compressor
  • Solid trolley construction
  • Automatic regulation by hygrostat
  • Professional automatic hot gas defrost
  • Dual MID-compliant meter for service hours and kilowatt-hours (optional)
