PWS7332A115N4SS is the SS variant of the large PWS 7332 air/water heat exchanger, wired for 115 V. It gives OEMs and facilities teams a high-capacity way to cool a sealed enclosure using a water source, for applications with high ambient temperatures, harsh conditions or frequent wash-down.
The PWS 7332 is rated 10748 BTU/h (3140 W) at +95 °F (+35 °C) enclosure and +50 °F (+10 °C) water. It circulates 441 CFM (820 m³/h) of air and needs 53 GPH (400 L/h) of coolant at rated capacity, within an operating pressure range of 14.5 to 145 PSI (1 to 10 bar). Compatible coolants include chilled water/glycol, tower water and other circulated coolants, which must be at least 10 °C colder than the inlet air.
- Electrical: 115 V, 60 Hz, 453 W, 3.8 A running current, terminal block connection
- Control: integrated thermostat and solenoid valve with alarm contact, +46 to +122 °F (+8 to +50 °C), factory set +95 °F (+35 °C)
- Heat exchanger: rugged 10 bar copper tube / aluminum fin, 1/2" barb connection
- Ambient air: +36 to +158 °F (+2 to +70 °C)
- Accessories: remote door switches, gasket kits, condensate bottle
The unit is 37.40 in (950 mm) high, 15.75 in (400 mm) wide and 7.56 in (192 mm) deep, and can be mounted on the side, the door or internally using the supplied PWS 7332/7152 drilling template. The PWS 7000 series lists UL, cUL and CE standards and compliance with NEMA 3R, 4, 4X. The PWS7332A115N4SS ships at 77 lbs (34.93 kg) and is REACH and RoHS compliant.
