F-22 Polyalphaolefin Liquid Coolant Carts

The Department of the Air Force is seeking information on potential sources and solutions for a Polyalphaolefin (PAO) Liquid Coolant Cart to support ground maintenance operations for the F-22 aircraft. The desired solution must be a robust, mobile unit capable of operating in a wide range of environmental conditions. The cart must be able to cool, clean, and recirculate PAO liquid coolant, and meet specific functional, operational, and system requirements. Interested parties are requested to provide company information, a proposed solution, a compliance matrix, manufacturing and delivery information, and information on existing solutions. • The cart must be compatible with polyalphaolefin (PAO) coolant. • The cart must contain a reservoir to allow for the bleeding of air from the PAO fluid. • The cart must include a 10-micron filtration system to ensure the cleanliness of the recirculated PAO fluid. • The cart must be capable of full performance in ambient temperatures ranging from -40°F to 120°F. • The cart must be a dual-powered system, capable of being powered by both an electric source and a diesel engine.
