Thermoelectric Enclosure Coolers

The internal temperature of an electrical enclosure must be closely monitored and controlled in order to protect sensitive equipment housed inside. Electrical equipment is susceptible to high temperatures and can result in shortened life expectancy of components and equipment failure. Unwanted heat can come from internal sources ( the components themselves) and external sources (environmental conditions). 

Enclosure thermoelectric coolers are solid-state heat pumps that use the Peltier Effect. This occurs when a direct current (DC) is passed through two different semiconductors, causing one side to get colder while the other side gets hotter. The cold side of the thermoelectric cooler is placed inside the enclosure and the hot side is placed outside the enclosure. Fans are used to circulate cool air throughout the enclosure.

Hoffman Thermoelectric Indoor/Outdoor Coolers have cooling capacities from 204 to 682 BTU/hour and remove heat around critical components within an enclosure. The low-profile, compact coolers use the Peltier effect to cool small indoor and outdoor enclosures and have a small footprint with DC powered operation, which is ideal for telecomm applications. The coolers are a low-maintenance, reliable solution with no compressors, condensers or filters required.
