SOLITHERM PELTIER cooling units and dehumidifier are based on the "Peltier" effect, which is derived from name of its inventor. When DC voltage is applied, Peltier elements generate a temperature difference which in combination with surface-enlarging heat sinks and forced ventilation, cause cooling inside the enclosure. The waste heat is dissipated into the environment via a separate ambient heat sink. Peltier units work without refrigerant, have no compressor and no pressure circuit, thus they can be installed in almost any position. However, the condensate management must be considered separately.

Thermoelectric cooling units are resistant to extreme ambient conditions and can operate even in very dusty or oily environments. The operating temperature range is  -20°C to 70°C. SOLITHERM PELTIER units can be used for both indoor and outdoor applications; the ingress protection rating is IP 66 or NEMA / UL Type 4X. With cooling capacities ranging from 30 W up to 800 W and AC and DC models available, they cover a wide range of cooling applications for the industrial sector.
