A high-profile client in the aerospace industry came to Fluid Industrial Manufacturing seeking a custom-made water cooled chiller for use in the F22 Raptor in order to keep the PAO oil at a specific temperature. We worked very closely with the client from start to finish, ensuring we met their every specification and detail. This chiller needed to be built with a cooling capacity to 68 KW (232,000 BTU/hr) and offer a temperature stability of ±3°F. On the piping we used 100% copper, 304 stainless steel on the tank, and 18 gauge sheet metal skins on the frame, resulting in a powerful, 2,700 pound chiller unit that keeps PAO oil at exactly 60°F.

This new unit featured multiple indicators and alarms and beneficial design elements, and went through a series of tests for quality and functionality. Upon completion, the custom manufactured water cooled chiller unit we created proved be have multiple benefits over the previous one the client had used: longer equipment life, increased energy efficiency, increased mean time between failures, and last but not least, it was significantly more economical than the previous supplier’s product, saving our client 35%. The client was beyond satisfied with the quality of the product and the money we saved them.

In Process Testing/Inspection Performed Our test facility is state of the art and can cool up to 50 tons and heat up to 100 kW.
We have up to 200 amp connections available.
When systems are larger than what our facility has we simply rent the necessary equipment to do the test (such as generators, large chillers, or large water heaters).
This chiller uses the heat of rejection (house water) to maintain the PAO oil at 60°F. Since this chiller has its own built in heater we did not have to use an electric heater in the tank to test the capacity of the unit. We simply connected to our house water loop and let the oil chiller run.
