Cooling solutions for industrial cabinets in corrosive and harsh production environments such as the food, beverage or pharmaceutical industry must meet increased requirements. Pentair offers the Hoffman WCHE air/water heat exchanger series for these areas of application. The filterless cooling systems, which are completely closed to the outside, do not pollute the environment with waste heat from the enclosure, and neither dust nor water can penetrate. The series enables cooling capacities from 870 to 12,500 W. The appliances are made of powder-coated sheet steel as standard, stainless steel versions are available on request. The appliances operate with an input voltage of 230 V in a temperature range of +5 to +70 °C ambient temperature and +10 to +50 °C internal cabinet temperature. The cooling capacity is regulated via a solenoid valve in the water circuit. The integrated fans are equipped with thermal protection.
