Seifert Systems' peltier coolers are made to effortlessly cool switchgear cabinets in environments where air is contaminated with aggressive vapors, oil or dust. Thermoelectric elements create a temperature difference between the inside and outside of the enclosure and make the internal air cooler. Integrated fans transport convection heat from the heat sinks connected to the peltier elements to the outside. The ready-to-use peltier coolers are available in 304 (V2A) or 316 (V4A) stainless steel, in seven designs from 30 to 800W cooling power. They can be mounted in almost any position. Seifert peltier coolers withstand the most extreme environmental conditions and at temperatures between -20 and +65°C, both indoor and outdoor applications, with an IP66 protection rating.
