Custom Industrial Process Chiller
A custom industrial process chiller is engineered around the specific demands of your equipment and operating environment. Rather than selecting a chiller by nominal cooling capacity alone, a complete system evaluation must account for true heat load, supply and return temperatures, flow rate, pump pressure, fluid properties, ambient conditions, electrical specifications, and control interfaces.

Air-Cooled vs. Water-Cooled Process Chillers
Air-Cooled Process Chillers
Air-cooled units reject heat directly into the surrounding ambient air.
Best suited for: Facilities without cooling tower access, standalone operations, applications where water conservation is prioritized, or outdoor installations.
Key considerations: Maximum ambient air temperature and adequate space ventilation (indoor heat rejection will raise room temperatures).
Water-Cooled Process Chillers
Water-cooled units transfer heat into a facility's cooling-water circuit or cooling tower loop.
Best suited for: Facilities with existing cooling tower infrastructure, applications requiring stable condenser water temperatures, or indoor installations where ambient heat rejection must be minimized.
Key considerations: Available condenser water temperature, pressure, and flow rate.
Critical Selection Factors: Flow, Pressure, and Fluid Properties
Pump Flow and Discharge Pressure
Cooling capacity alone is useless if the fluid cannot reach the heat source. Pump selection must account for total loop pressure drop, including pipe length, elbows, valves, filters, elevation changes, and heat exchanger restriction. Motor horsepower (HP) is not a substitute for verified flow and pressure metrics.
Process Fluid Characteristics
Water and glycol mixtures behave differently. Increasing glycol concentration raises fluid viscosity and pumping resistance while slightly reducing heat transfer efficiency. Fluid composition directly impacts both evaporator sizing and pump selection.
OEM Equipment Integration
For machinery manufacturers, a process chiller functions as a sub-component within a larger platform. OEM configurations support:
Custom cabinet dimensions and restricted footprint envelopes.
Customized piping layouts and machine-side process connections.
Specific electrical voltages, terminal block layouts, and control interlocks.
Remote control protocols (RS485, Modbus, Siemens PLC interfaces).
Compliance with international standards including CE, UL, and ISO 9001.
Repeatable manufacturing consistency across production batches.

05
Common Selection Pitfalls to Avoid
Selecting by Nominal Tonnage Alone: Failing to verify output at actual operating supply temperatures.
Specifying Motor Power Instead of Flow/Pressure: Relying on pump HP rather than actual flow rate and head pressure.
Ignoring Glycol Effects: Overlooking how viscosity changes affect heat transfer and pump performance.
Overlooking Ambient Extremes: Underestimating performance drop-off during peak summer ambient temperatures.
Comparing Price Without Technical Scope: Comparing proposals without evaluating rating conditions, pump curves, control interfaces, or build quality.
