Enclosure thermal management devices provide optimum conditions to prevent component failure due to overheating and/or condensation. These devices include air conditioners, heat exchangers, Vortex coolers, thermoelectric coolers, heaters, fans, venting devices and control units.
An important consideration with electrical enclosures is the regulation of the temperature inside. Both external factors and internal electrical devices can cause wide temperature fluctuations within an enclosure. If not properly regulated, this fluctuation can cause damage to sensitive electrical equipment. Controlling the internal temperature of an enclosure can eliminate the risk of condensation and prevent overheating or freezing of the electrical components.

Enclosure air conditioners are designed with internal closed loop cooling systems that provide optimum cooling and protection from dust, oil, and water, by keeping the ambient air outside the enclosure. These air conditioners are environmentally friendly and provide CFC-free service.
Thermoelectric coolers utilize internal and ambient heat sinks to dissipate heat into the external environment; they are resistant to extreme ambient conditions and can operate effectively even in dusty and oily environments.
Air to air heat exchangers are closed loop systems that offer low operating cost and low maintenance.
StegoJet compact fans provide spot cooling for "hot spots" and high heat load components inside an enclosure.
Filter fans displace hot air inside the enclosure with cooler air from the outside (purchase intake/exhaust grille separately).
Filter fans are available in various voltages, NEMA ratings, and in a range of airflow options.
Compressed air cooling is used where conventional enclosure cooling by cabinet air conditioners or heat exchangers is not possible.
Enclosure heaters controlled with thermostats, hygrostats and hygrotherms protect against condensation. They heat the air inside enclosures, preventing water vapor from condensing on components while providing the greatest possible air circulation and low energy consumption.
Thermostats and hygrostats regulate temperature and humidity inside an enclosure. Electronic and mechanical models are available, with fixed or adjustable setpoints to fit a wide range of applications.
Vents are ideal for applications where natural convection provides sufficient cooling for enclosure contents.
Grilles work together with filter fans to supply filtered cooler ambient air from outside the enclosure, reducing internal heat and protecting the devices inside the enclosure.
Breathers and drains allow fresh air from the outside to enter the enclosure, providing the necessary cooling for the components within while maintaining the NEMA rated protection.
Compensators are used to control the pressure inside a tightly sealed enclosure and compensate for pressure fluctuations caused by temperature changes.
