Hammond PWS7152A115N4LG 5100 BTU/H 115V Air-to-Water Heat Exchanger

The PWS7152A115N4LG is a 5100 BTU/H air-to-water heat exchanger for 115 V supplies, described by the manufacturer as NEMA 3R/4 in light gray. It sits between the PWS 7102 and PWS 7332 in capacity and is designed to use various water sources to cool enclosures where ambient conditions involve high temperatures, harsh conditions or frequent wash-down.

PWS 7000 series units are compatible with chilled water/glycol, tower water and other circulated coolants. An integrated thermostat and solenoid valve with alarm contact provide automatic temperature control, and the rugged 10 bar copper tube / aluminum fin heat exchanger connects with 1/2" barb fittings. The installation manual notes that the cooling liquid must be at least 10 °C colder than the heat exchanger inlet air, that the maximum permissible operating pressure is 10 bar, and that flexible pressure-resistant (>10 bar) hose secured with clamps should be used.

This model shares the PWS 7332/7152 drilling template, which is supplied with the unit, and its drawing shows an overall height of 950 mm (37.40 in) and width of 400 mm (15.75 in). Side, door or internal mounting is supported. The series exterior case is galvanized steel finished RAL7035 light gray, and the low noise, maintenance-free design suits sealed panels.

The PWS 7000 series lists UL, cUL and CE standards. The PWS7152A115N4LG ships at 55 lbs (24.95 kg), is REACH and RoHS compliant, and carries UPC 623980720456. Remote door switches, gasket kits and a condensate bottle are offered as accessories.
