Enclosure Compressed Air AC 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 compressed air ac coolers are devices that use a compressed, filtered air stream and spin it into a high-speed vortex. This vortex splits the air into a hot stream of air and a cold stream of air. The cold stream is placed into the enclosure which displaces the warm air inside and exhausts it with the hot air stream out of the enclosure.
Hoffman Hazardous Location Vortex A/C Enclosure Coolers have cooling capacities up to 5,000 BTU/hour and are ideal for applications where compressed air is available in hazardous locations. They are approved for 175 degrees F maximum ambient temperature in Class I, Div 2; Class II, Div 2 and Class III areas. They have top, side and front mounts and a built-in mechanical thermostat for reducing energy consumption.
Hoffman VORTEX A/C Enclosure Coolers have cooling capacities up to 5,000 BTU/hour and are ideal in areas with limited space and where compressed air is available. They have top, side and front mounts and a built-in mechanical thermostat for reducing energy consumption. These systems are reliable and virtually maintenance free with almost no moving parts.
Products
Common modifications or accessories that are used to enhance electrical cabinets.
Lighting kits. Lighting kits are often used in outdoor applications. There are many different styles of lighting kits that can be used, but LEDs have become the preferred lighting solution in the past several years.
Pressure switches. Pressure switches operate on a spring and react to the cabinet door opening and closing. They can be used for lights, intrusions alarms and exhaust fans.
Passive air vents. Passive air vents allow natural air circulation to flow through a cabinet providing proper ventilation.
Enclosure fans. Enclosure air fans are used when more ventilation is required. The size of the fan will depend on the size of the enclosure as well as the amount of air that needs to be circulated.
Air conditioners. Air conditioners are used when ambient air circulation is inadequate to cool the cabinet. The air conditioner size will depend on the enclosure size, ambient air temperature and heat generated within the cabinet.
Heaters. Heaters are used when a cabinet is located in areas that may be exposed to cold temperatures.
Locking mechanisms. Locking mechanisms are used to secure cabinets.
Conduit hole seals. Conduit hole seals are used on cabinets that have holes that need to be plugged after conduit has been removed.
