Shiballoy - Exair provides cabinet coolers. These coolers help cool electrical panels so as to prevent overheating. Following are some of the technical features of this air conditioner which include: non-hazardous purge [NHP] cabinet coolers keep dirt and smoke out of electrical enclosures in non-hazardous areas; convert an ordinary supply of compressed air into cold air without the use of refrigerants or environmentally harmful CFCs; are simple to install and operate and have no moving parts or requirements for maintenance. The cabinet cooler uses 1SCFM of air to maintain a slight, positive pressure inside the electrical enclosure, under normal conditions. When an increase in temperature is detected by the thermostat, it energizes a solenoid to start full airflow to the cabinet cooler, producing full cooling capacity inside the panel. NHP cabinet coolers have cooling up to 2800Btu/hr. and are suited for NEMA 12, 4 and 4X enclosures. Corrosion resistant stainless steel construction is available and all models are UL listed.
