Unit pictured is representative of the series; dimensions and connections vary by part number - see the table below.
Construction
Coil
- Copper tubes, aluminum fins, multi-pass. The size digits in the model number (08, 12, 16 ... 75) follow the same core sizes as the A Series air-cooled aftercoolers.
Pump and controls
- Close-coupled centrifugal pump with a starter in a NEMA enclosure, an expansion tank and a three-way bypass valve for temperature control.
Frame
- Steel or aluminum casing on a structural base; frame letter A, B or C in the model number indicates the frame size.
Options
- Glycol service, low-ambient fan control, larger pumps for longer runs, dual-pump stations and custom capacities.
Why a closed circuit
Keep the treated water in, keep the plant water out
- No tower, no evaporation, no water treatment drift
- Outdoor installation with glycol protection
- One package: pump, coil, controls and expansion tank

Applications
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
