This is a Commercial Only One Source Justification (NTE SAT) filed in accordance with FAR 12.102(a) for a Naval Supply System (NAVSUP) Fleet Logistics Centers (FLC) procurement. Purchase Request Number 1301328973 / N218716008W181 is for OEM Marc Climate Controls, Inc. replacement parts—specifically a Condensing Unit (PN: CMSX18-216-M-C1) and Air Handler Unit (PN: WAMX18-216-M-C1)—to be delivered by June 6, 2026, to MSC Bats Warehouse in San Diego for installation onboard USNS Rappahannock (T-AO 204). The manufacture is classified under CAGE Code 0X694 (INACTIVE) and is designated as a small business per NAICS standards.

The justification asserts that Marc Climate Controls, Inc., a division of Shieldt Air Solutions, Inc., is the only available source based on brand name requirements. The condensing and air handling units are direct replacement parts that must be compatible in all aspects (form, fit, and function) with existing systems to prevent ammunition locker explosions and ensure equipment reliability. The document states that original equipment manufacturers have access to necessary technical data and expertise for providing compatible replacement parts, and that no known alternative replacements meeting government requirements have been identified through market research.
