F-22 Polyalphaolefin Liquid Coolant Carts

The Department of the Air Force Materiel Command Lifecycle Management Center is seeking potential sources for a Polyalphaolefin (PAO) Liquid Coolant Cart designed to support ground maintenance operations for F-22 aircraft. This trailer-mounted system must cool, clean, and recirculate PAO liquid coolant during avionic system operations when the aircraft's Auxiliary Power Unit cannot be operated. Mandatory functional requirements include PAO compatibility, air bleeding reservoir capability, and 10-micron filtration, while operational requirements specify full performance across ambient temperatures ranging from -40°F to 120°F with dual-powered capability using either electric power (440-480V/60Hz at 120 amps or 380V/50Hz at 152 amps) or a diesel engine. The system must deliver 35 kW heat load capacity for both forward and aft liquid loops, maintain 31 gpm coolant flow at 150 psig supply pressure, and achieve a target supply temperature of 75°F. Interested parties must submit responses electronically by February 27, 2026 at 1600 MST to james.recker@us.af.mil and ali.srader@us.af.mil, including company information with CAGE code, detailed technical specifications with datasheets, a compliance matrix, manufacturing capabilities, lead times, and clarification on whether the solution represents a commercial-off-the-shelf product, modified COTS product, or new design.

This Pre-Solicitation Notice carries no set-aside designations, and no incumbent contractor or current award value information has been disclosed at this stage. The procurement focuses on a single trailer-mounted unit compatible with standard tow vehicles and F-22 interface hoses equipped with quick-disconnect adapters. The Request for Information represents an early market research phase to identify qualified sources prior to formal solicitation, with no specific quantity or contract award value specified in this phase. Respondents should be prepared to demonstrate manufacturing capabilities and realistic lead times, as the Air Force will use the submitted information to assess technical feasibility and vendor qualification for potential follow-on acquisition. The NAICS classification 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing) and PSC category 1730 (Aircraft Ground Servicing Equipment) indicate the expected industrial base for this specialized aviation support equipment.
