Practice-oriented typical applications:

Convincing process advantages through the TTR Trisorp Dual principle

Basically conventional desiccant dehumidifiers are equipped with a common air inlet (mono) for dry and regeneration air, e.g. all Trotec machines that operate according to the Trisorp-mono or Bisorp-mono principle.

These dehumidifiers are not suitable for through-air drying directly in the respective room as a process-related low pressure is generated and therefore drawing air from the outside is blown into the room, whose moisture content cannot be controlled.

An outdoor installation, e,g in near rooms can be done with all TTR models (example 1).

Due to the ventilation with drier fresh air, a pressure overload is generated, which leads moist air to the outside. However, with this version the dehumidification rate always depends on the moisture content of the sucked "outdoor air". With a nominal amount of dry air it achieves a reduction in the dew point temperature by approx. 5 to 10 °C (depending on the machine).

Power-saving dehumidification and higher drying rates thanks to circulatory air operation with dual air circuits

The D models TTR 400 D and TTR 500 D operate according to the TTR Trisorp Dual principle with two separate air flows and separate fans for each circuit. This means that circulatory air operation is also possible with an outdoor installation supplied by a process air circuit that is separated from the "outdoor air" (example 2). Even if the D models are installed indoor in a room that is to be treated with dry air, a pressure-neutral circulatory air operation is possible by streaming incoming regeneration air and outgoing moist air out of the room by means of a hose or pipe connection (example 3).

Variable circulating air drying with TTR-D models have decisive advantages for users:

If there is a nominal amount of dry air, up to 30 °C lower dew point temperatures can be achieved compared to the "outdoor air" that supplies the regeneration air, in contrast to conventional through-air operation. Therefore, dew points far below 0 °C can be achieved, which results in considerably lower drying stages and in considerably more energy-efficient operation!
