Stainless steel desiccant dehumidifier TTR 250 HP

Special design for particularly long air transport distances ...

The TTR 250 HP is not only standard-equipped with a radial fan but also with an additional extra-powerful fan motor which allows an especially high compression.

This makes this dehumidifier especially well-suited for applications where air has to be transported over long distances or several levels, for example ships’ rooms, cellars or bunkers.

The standard ex factory configuration of the TTR 250 HP is designed for the transportation of moist air. The dryer can be set by the customer to a different configuration, should the need arise for high-pressure dry air to be conducted away instead of moist.

With the TTR 250 HP you can benefit from a professional desiccant dehumidifier originally produced by Trotec which has been developed and manufactured according to the highest of quality standards in Germany.

Dual counter with additional MID-compliant registration of the power consumption (optional)

The standard operating hours counter of the TTR 250 HP is optionally also available as a dual counter for the additional MID-compliant registration of the power consumption.

A few practical benefits:

  • Professional quality “made in Germany
  • Corrosion-resistant stainless steel housing
  • Reliable silica gel sorption rotor in washable and mechanically high-tensile finish
  • Additional extra-powerful fan motor which allows an especially high compression
  • Integrated heat recovery
  • Self-regulating PTC heating
  • Ampere meter to control the operating condition
  • Operating hours counter
  • Dual counter with additional MID-compliant* registration of the power consumption (optional)

* What does MID compliant mean?

The European Measuring Instruments Directive (MID) has replaced the existing rules of national approval and subse-quent calibration in some areas. As a result, all power meters, which are used for energy consumption billing, must be MID compliant in the future.
