The solution: closed-circuit dehumidification systems
Stationary Trotec air dehumidifiers are individually-scalable, self-contained dehumidification systems that do not require an additional fresh air supply. They can be optimally adapted to all environmental requirements and can be retro-installed in existing facilities without problem.
Environmental air humidity regulation is controlled hygrostatically or by dew point. The wide working range from -15 °C to +70 °C provides rapid, economical dehumidification in a multitude of applications. The dehumidifiers are also suitable for use with existing air handling systems.
The environmental air is fed into the refrigeration dryers and is cooled to below its dew point, whereupon a large proportion of the humidity in the air condenses and can be extracted from the air.
The condensate is removed and the dry, cold air is fed past the heating element of the cooling block where it is heated by the released process energy and released back into the environmental air.
You can also benefit from this principle
in two different ways:
In all environments where heating of the environmental air is required, supplementary heating costs can be substantially reduced by utilising the heated dry air.

In low-temperature environments, it is possible to reclaim heat. In this case, water can be heated by the released process heat and used for existing heating processes or for water treatment.

Especially in the case of applications with high water consumption, for example slaughterhouses or commercial kitchens, energy costs can be reduced significantly.
As an alternative, it is possible to utilise an external heating element that is remote from the area that is to be dehumidified.
