Hammond PWS3302A230N4LG 12283 BTU/h Air/Water Heat Exchanger, 230V Light Gray

The PWS3302A230N4LG is a full-height air/water heat exchanger from the PWS 3000 Series: the highest-capacity model of the 7000-12000 BTU/H PWS 3000 range, sharing the 51.89 in housing of the PWS 3202 while delivering 12283 BTU/h. 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 3302 is rated at 12283 BTU/h (3600 W) at +95 F (+35 C) enclosure and +50 F (+10 C) water; it moves 315 CFM (535 m3/h) of enclosure air on 2 GPM (450 L/h) of coolant at rated capacity. This is the 230 V version, specified for 50/60 Hz supply; it consumes 59.0 W and draws 0.31 A running current, with a terminal block power connection. An integrated thermostat and solenoid valve with alarm contact provide automatic temperature control.

The exterior case is galvanized steel finished in RAL7035 Light Gray, and the part description rates this variant NEMA/Type 3R/4. Inside, a rugged (10 bar) copper tube / aluminum fin heat exchanger connects through a 1/2 in barb. The series ordering table gives the unit as 51.89 in (1318 mm) high, 15.76 in (400 mm) wide and 9.07 in (230 mm) deep, while the part page lists a size of 53.89 in x 16.76 in x 10.07 in (1,369 mm x 426 mm x 256 mm). Shipping weight is 70 lbs (31.75 kg). The series is rated UL, cUL and CE.

Its control range adjusts from +46 to +122 F (+8 to +50 C), factory set at +95 F (+35 C), and the unit is specified for ambient air from +36 to +158 F (+2 to +65 C). 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.
