Custom industrial refrigeration chillers are engineered for applications where standard catalog models cannot match required cooling capacity, fluid supply temperature, system flow, pump pressure, coolant type, electrical standards, or space constraints.

Instead of selecting from fixed model numbers, our engineering process begins directly with your process parameters. We evaluate heat load, fluid dynamics, ambient site conditions, material compatibility, condenser requirements, controls, and enclosure dimensions before finalizing any configuration.

How to Evaluate a Custom Chiller Supplier

When comparing custom chiller proposals, verify that the supplier confirms the following:

Cooling capacity calculated at actual operating temperatures rather than nominal laboratory conditions.

Verified flow rate and pump head matched to overall piping resistance.

Complete material compatibility for all wetted components.

Certified compliance with CE, UL, or ISO 9001 standards.

Provision of technical deliverables including product datasheets, dimensional drawings, and electrical schematics.

FAQ

Q: What is the main difference between a custom industrial chiller and a standard model?

A: A standard chiller uses fixed performance ratings, standard internal pumps, and predefined cabinet footprints. A custom industrial chiller is engineered around specific process parameters-such as extreme ambient limits, non-standard operating temperatures, aggressive process fluids, higher pump pressure, specific PLC protocols, or custom dimensional limits.

Q: Can a custom chiller be configured for high ambient outdoor environments above +45°C?

A: Yes. For extreme ambient conditions, the chiller is engineered with expanded condenser surface area, high-airflow fans, specialized compressor pressure ratios, and tropicalized electrical enclosures to prevent high-pressure trips and maintain full cooling capacity.

Q: Can deionized (DI) water or corrosive liquids be used as the cooling fluid?

A: Yes. When handling DI water or corrosive process fluids, all wetted internal components-including the heat exchanger, pump impellers, internal piping, valves, and fluid sensors-are selected using compatible materials such as 316L stainless steel, titanium, or high-grade polymers.

Q: Is it possible to cool multiple independent machines with a single custom chiller?

A: Yes. Chillers can be configured with multiple independent refrigeration circuits, dual supply/return manifolds, or secondary pump loops to supply fluid at varying temperatures or pressures to multiple machines simultaneously.

Q: How are custom chillers integrated into OEM machinery interfaces?

A: For OEM machinery, the chiller frame, piping connections, electrical layout, and control software are built according to the OEM machine envelope. Communication protocols (such as Modbus, Profinet, or Ethernet/IP) and physical mounting points are customized for seamless factory assembly and direct controller communication.
