Enclosure climate control

Eaton's B-Line series climate control products help address electrical enclosure ventilation and cooling requirements.

Climate control products

Eaton's B-Line series climate control products include an extensive array of units for virtually every type of application which customers can select from to address their enclosure ventilation or cooling requirement.


Forced ventilation air cooling

In clean, non-hazardous environments with acceptable ambient temperatures, a simple forced-air cooling system utilizing ambient air is usually adequate. Combined with a low-cost air filter, such devices generally meet the heat removal needs of typical electronic and electrical equipment.

Closed-loop cooling

In harsh environments involving high temperatures, heavy particulates, oil, or chemicals capable of damaging components, ambient air must be kept out of the enclosure. Sealed enclosures are generally used, with closed-loop cooling consisting of two separate circulation systems in a single unit. One system, sealed against the ambient air, cools and recirculates the clean cool air throughout the enclosure. The second system uses ambient air or water to remove and discharge the heat.
