Enclosure Air Conditioners & Cooling

 

The internal temperature of 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 critical components and equipment failure. Unwanted heat can come from internal sources ( the components themselves) and external sources (environmental conditions). There are four main methods for enclosure cooling: air conditioners, thermoelectric coolers, compressed air coolers and air-to-air heat exchangers.
