The PWS7332A230N4SS is a large air/water heat exchanger from the PWS 7000 Series: the 10748 BTU/h model of the PWS 7000 Series (3000-10000 BTU/H), a 37.40 in tall unit for heavily loaded enclosures. Panel builders and OEM designers use it to cool enclosures with chilled water/glycol, tower water or other circulated coolants where ambient conditions are hot, harsh or subject to frequent wash-down.
The PWS 7332 is rated at 10748 BTU/h (3140 W) at +95 F (+35 C) enclosure and +50 F (+10 C) water, moving 441 CFM (820 m3/h) of enclosure air with a coolant flow of 53 GPH (400 L/h) at rated capacity. This is the 230 V version, specified for 50/60 Hz supply; it consumes 385 W and draws 1.95 A running current, with a terminal block power connection. An integrated thermostat and solenoid valve with alarm contact provide automatic temperature control.
Inside, a rugged (10 bar) copper tube / aluminum fin heat exchanger connects through a 1/2 in barb. The part page lists this variant simply as an air/water heat exchanger for 230V, with a shipping weight of 77 lbs (34.93 kg). The PWS 7000 Series is rated UL, cUL and CE and complies with NEMA 3R, 4, 4X. The unit measures 37.40 in (950 mm) high, 15.75 in (400 mm) wide and 7.56 in (192 mm) deep.
The adjustable control range is +46 to +122 F (+8 to +50 C) from a +95 F (+35 C) factory setting, and the unit is specified for ambient air from +36 to +158 F (+2 to +70 C). The part drawing shows the PWS 7332/7152 drilling template with fourteen 10.70 mm (0.42 in) mounting holes. Side, door or internal mounting gives installation flexibility, and the low noise design is maintenance-free. The manual requires coolant at least 10 C colder than the inlet air.
Ideal For
- Closed-loop cooling of heavily loaded sealed enclosures
- Outdoor enclosures
- High-temperature ambient conditions
- Enclosures subject to frequent wash-down
