RNK International, Inc.

RNK International, Inc., doing business as RNK International Inc., is a minority-owned, self-certified small disadvantaged business that supplies HVAC equipment, refrigeration components, plumbing fixtures, and mechanical parts to federal agencies as a prime contractor on 99 percent of its recent awards. Headquartered in Irvine, California, and structured as a Subchapter S corporation, RNK competes predominantly under total small business set-asides and full-and-open procurements across Defense Logistics Agency, Air Force, Army, State Department, Federal Bureau of Prisons, and Coast Guard platforms.

RNK's capability footprint centers on air-cooled chillers, boilers, water heaters (electric and steam), evaporator coils, refrigeration compressors, condensing units, ball valves, check valves, fans, and related HVAC components. Representative work includes a $285,048 total small business set-aside purchase order from the Coast Guard (September 2026) for Carrier factory-assembled chillers and heat pump systems at USCG Training Center Cape May, New Jersey; a $130,665 award from the Federal Bureau of Prisons (December 2026) for a 160-ton ASHRAE 90.1-compliant air-cooled scroll chiller at Federal Prison Camp Bryan, Texas; a $96,315 total small business set-aside from Air Combat Command (September 2024) for boilers supporting four buildings at a military installation; and a $81,660 award from Air Combat Command (July 2024) for a 20-ton portable chiller for the 7th Combat Engineer Squadron. RNK also holds a $250,000 single-award indefinite delivery contract with Defense Logistics Agency Land and Maritime for gasket products.

Customer concentration is extreme and defense-oriented. The top five funding agencies account for 74 percent of recent award count, led by Defense Logistics Agency Troop Support Construction and Equipment (703 awards, $6.9 million combined potential value) and Defense Logistics Agency Land and Maritime (387 awards, $1.1 million). The Department of State Bureau of Overseas Building Operations, the Department of the Air Force, and the Department of the Army round out the active set. By dollar magnitude, the rankings align closely: DLA Troop Support and DLA Land and Maritime together anchor 78 percent of combined potential value at $8 million, followed by State Department at $892 thousand and Air Combat Command at $871 thousand. RNK's largest named parent vehicles are indefinite delivery contracts with DLA, including DABJ0103D0016 (5 task orders, $249 thousand combined potential value) and several others carrying 3 to 10 task orders each.

Activity has remained steady year over year — 43 awards in 2022 climbing to 56 in 2025, with 36 recorded in 2026 through the current date. Only four awards face ultimate completion inside the next twenty-four months, carrying combined potential value of $491 thousand, signaling minimal recompete pressure in the near term. RNK subcontracts minimally (1 percent of recent awards); recent sub work includes supply and installation of domestic water heaters and HVAC package units under task orders with Asrc Federal Facilities Logistics, LLC (May 2024). Across all named awards, RNK operates without stated major prime contractors anchoring its footprint; the subcontract portfolio is fragmentary and small. RNK's NAICS concentration spans air-conditioning and refrigeration equipment manufacturing (490 awards), industrial valve manufacturing (184 awards), and heating equipment manufacturing (72 awards), with corresponding PSC focus on refrigeration and air-conditioning components, space and water heating equipment, air-conditioning equipment, and valves. The vendor competes as a prime on routine, single-award purchase orders drawn from DLA and Air Force Construction and Equipment indefinite delivery vehicles, with delivery cycles typically 60 to 170 days and order values ranging from under $500 to mid-six-figure totals.
