The Naval Air Warfare Center Weapons Division in China Lake, California, intends to sole-source the procurement of one lot of a Thermotron Portable Temperature Conditioner and accessories from Thermotron Industries in Holland, Michigan. This is due to the requirement for equipment that is compatible with existing systems and controls for testing. Any firm believing it can fulfill this requirement may submit a written capability statement via email for agency consideration within 5 days of the notice's publication. All responsible sources must have an active registration in the System for Award Management (SAM), which now requires a notarized letter for registration or renewal.
