Where a process needs cooling water but a cooling tower is the wrong answer - because the water must stay clean, because evaporation and make-up are unwelcome, or because there is simply no tower - a closed-circuit cooler rejects the heat to air instead. The WAC Series does it as a complete package: the pump, the fin-tube radiator, the fans, the expansion tank and the three-way temperature control valve arrive on one frame with one power connection and two pipe connections.
Nine standard sizes cover 62,000 to 476,000 BTU/hr at a 90°F ambient with water entering at 140°F and leaving at 115°F. Larger duties to 3,000,000 BTU/hr, glycol service and dual-pump stations are built to order.

Where They Are Used
What We Need to Quote
A selection comes together quickly once the duty is stated.
- Compressor SCFM and pressure, or the heat load
- Inlet temperature and the cooling water or ambient temperature
- Required outlet temperature
- Design pressure and any code stamp
Replacing an Existing Unit
Where a unit is being replaced, the nameplate does most of the work.
- IPAC or HiROSS model number, exactly as stamped
- National Board number where one is fitted
- Connection sizes and orientation
