EXAIR's new Dual 316 Stainless Steel Cabinet Cooler® Systems keep electrical enclosures cool with 20°F (-7°C) air while resisting heat and corrosion that could adversely affect the internal components. The wear, corrosion, and oxidation resistance of Type 316 stainless steel assures long life and maintenance free operation. The high cooling capacity of up to 5,600 Btu/hr. is ideal for large electrical enclosures and high heat loads. Models with lower cooling capacities for NEMA 12, 4 and 4X enclosures are also available.
