1 Noren Products Heat Exchangers Low Cost, Energy Efficient Cooling for Electrical Enclosures

2 Overview Modern electronics continue to be placed in denser packaging and smaller enclosures, often causing overheating problems Moisture and airborne dust, oil, dirt, and other contaminants are damaging to sensitive electronic equipment. The Compact Cabinet Cooler is an air-to-air or air-towater heat exchanger that solves these problems by cooling and re-circulating the clean air inside the cabinet. At the same time, a cabinet cooler maintains the enclosure s protective seal against contaminants. They are UL/cUL Listed and come in many different integrities including NEMA 12, 4, and 4X.
