Thermal Spray Chiller for HVOF & Plasma Spray Cooling
APT thermal spray chillers provide closed-loop water cooling for HVOF spray guns and plasma spray torches used in thermal spray coating systems. Each system can be configured according to cooling capacity, flow rate, pump pressure, water temperature, voltage, control interface, ambient temperature, and workshop installation conditions.
What Matters Most in Thermal Spray Cooling?
A thermal spray chiller should be selected around cooling load, water temperature, flow rate, pump pressure, water quality, working hours, ambient temperature, voltage, and control interface. For HVOF and plasma spray systems, stable closed-loop cooling helps protect the spray gun or plasma torch and supports repeatable coating operation during continuous production.
The correct chiller is not selected by horsepower alone. APT reviews the thermal spray equipment model, cooling circuit data, required flow, pressure, temperature range, workshop conditions, and whether the system should be air-cooled, water-cooled, or customized.

Thermal Spray Chiller FAQ
These questions help engineers and buyers prepare thermal spray cooling data before requesting a formal quotation.
What is a thermal spray chiller?
A thermal spray chiller is an industrial closed-loop cooling system used to control circulating cooling water for HVOF spray guns and plasma spray torches.
What size chiller do I need for an HVOF thermal spray system?
The required chiller size depends on the heat load of the HVOF spray gun cooling circuit, required flow rate, pump pressure, target water temperature, operating hours, and ambient temperature.
What size chiller do I need for a plasma spray system?
A plasma spray system usually requires stable cooling water for the plasma torch. The chiller should be selected according to heat load, flow rate, pump pressure, water temperature, and continuous working time.
Why do HVOF and plasma spray systems need closed-loop cooling?
Closed-loop cooling helps maintain stable water temperature, reduce water quality fluctuation, protect the spray gun or plasma torch, and support repeatable coating operation during continuous industrial production.
Can APT chillers provide customized pump pressure and flow rate?
Yes. APT can configure pump pressure and flow rate according to the cooling circuit requirements of HVOF spray guns, plasma spray torches, and other thermal spray equipment. Customers should provide required flow, pressure, and circuit details for accurate selection.
Should I choose an air-cooled or water-cooled chiller for thermal spray cooling?
Air-cooled chillers are practical for standalone workshops or sites without cooling tower water. Water-cooled chillers may be preferred for high-duty indoor operation, centralized cooling, or factories with existing condenser water systems. Final selection depends on capacity, ambient temperature, ventilation, and installation conditions.
Can one chiller cool both HVOF and plasma spray equipment?
One chiller may be used if the total heat load, flow rate, pump pressure, water temperature, and cooling circuit design are suitable. For different equipment requirements, APT can review whether a single circuit, dual circuit, or separate chiller configuration is more appropriate.
What cooling medium is recommended for thermal spray chillers?
Water is commonly used for standard indoor thermal spray applications. Glycol solution, DI water, or special fluid may be considered when low temperature, freeze protection, water quality, or equipment requirements demand it.
Can the chiller communicate with the coating system?
Yes. APT thermal spray chillers can be configured with alarm output, PLC, HMI, Modbus communication, remote start/stop, flow protection, and interlock signals when required by the coating system.
Can APT chillers operate in dusty thermal spray workshop environments?
APT can design chillers with industrial-grade components, protected electrical cabinets, practical maintenance access, filtration considerations, and installation review for dusty thermal spray workshop environments.
What information should I provide for a thermal spray chiller quotation?
Please provide thermal spray process type, equipment model, cooling capacity or heat load, water temperature, flow rate, pump pressure, cooling medium, voltage, ambient temperature, installation location, and control interface requirements.
Can APT customize a chiller for imported HVOF or plasma spray equipment?
Yes. APT can review imported HVOF or plasma spray equipment based on machine model, nameplate, manual data, cooling water requirements, voltage, flow, pressure, and control interface information.
