USAF – F22 Raptor

Problem Statement

The United States Air Force (USAF) came to Chillermen seeking a custom-made water-cooled chiller for use in the F22 Raptor to keep the PAO oil at a specific temperature. 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.

Benefits

The custom-made water-cooled chiller from Chillermen has provided the USAF with several benefits, including:

• Increased energy efficiency: The chiller is more energy efficient than the previous system, which has saved the USAF money on their energy bills.
• Increased mean time between failures: The chiller is more reliable than the previous system, which has resulted in less downtime for the aircraft.
• Longer equipment life: The chiller is built to last longer than the previous system, which will save the USAF money on replacement costs.
• User-friendly serviceability: The chiller is easy to service, which has reduced the maintenance costs for the USAF.

Conclusion

The custom-made water-cooled chiller from Chillermen has been a success for the USAF. The chiller has solved the problem of the high PAO oil temperatures in the F22 Raptors and has provided the USAF with several benefits, including increased energy efficiency, increased mean time between failures, longer equipment life, and user-friendly serviceability.
