Electrical enclosures are typically cooled by natural and forced ventilation. However, in some cases, electrical panels may overheat due to internal heat loads, environmental, ventilation and airflow capacity limitations. In these cases, enclosure air conditioning can address high temperatures within electrical enclosures, thereby increasing component life and reducing the risk of overheating leading to component failure.

• Impact of Heat Load
  The heat load of an electrical enclosure is usually expressed in watts. Heat sources include electrical equipment, solar radiation and ambient heat. For example, power supplies, servo drives, motor drives, and transformers are typically between 85% and 95% efficient, with the remaining 5% to 15% of the energy converted to heat.
• Thermal industrial environments
  Electrical enclosures in hot industrial environments, such as near furnaces and kilns, cannot rely on natural cooling because the ambient air temperature is near or above the optimal temperature for electrical equipment. In such cases, enclosure air conditioning is the only viable method of maintaining safe electrical equipment operating temperatures.
• Hot Outdoor Climates
  In hot climates, the surface temperature of metal equipment can easily exceed 100° F. Under these conditions, natural ventilation may not be sufficient to prevent the internal temperature of electrical enclosures from reaching unsafe levels. These conditions are common in hot, dry, tropical and subtropical regions.
• Dusty Environments
  In dusty environments, electrical equipment needs to be properly enclosed and natural ventilation is not recommended because dust and dirt may affect the operation of moving parts of relays and contactors.
