RNK International, Inc.

RNK International, Inc., a minority-owned, self-certified small disadvantaged business based in Irvine, California, supplies HVAC equipment, refrigeration components, plumbing fixtures, and mechanical parts to federal agencies as a prime contractor on 99% of recent awards, competing predominantly under total small business set-asides and full-and-open contracts. The company is a Subchapter S corporation and Subcontinent Asian American-owned entity that has established itself as a high-volume transactional supplier across the Defense Logistics Agency, the Department of the Air Force, the Department of the Army, the Department of State, and the Federal Bureau of Prisons.

RNK International's capability footprint centers on the procurement and delivery of standardized HVAC and refrigeration equipment—electric water heaters, air-cooled chillers, boiler systems, evaporator coils, ball valves, condensing units, and related components. Representative prime work includes a $91,833 purchase order from the Federal Bureau of Prisons for an air-cooled scroll chiller meeting ASHRAE 90.1-2019/2022 compliance (awarded July 2026); a $96,315 total small business set-aside from Air Combat Command for HVAC boiler systems supporting four buildings at a military installation (September 2024); a $81,660 total small business set-aside from Air Combat Command for a 20-ton portable chiller (July 2024); and a $74,340 total small business set-aside from the Federal Bureau of Prisons for steam-to-hot water vertical heaters at Federal Correctional Institution Lewisburg, Pennsylvania (June 2025). The company holds a $250,000 single-award indefinite delivery contract with Defense Logistics Agency Land and Maritime for gasket products. RNK International also subcontracts to Asrc Federal Facilities Logistics on task orders for packaged HVAC units and domestic water heater installation and servicing work.

Customer concentration is extreme and favorable. The top five funding agencies account for 74% of award count; Defense Logistics Agency Troop Support Construction and Equipment dominates at 696 awards ($6.8 million combined potential value), followed by Defense Logistics Agency Land and Maritime (384 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 concentration is tighter: DLA Troop Support and DLA Land and Maritime together represent 52% of combined potential value. The company's award velocity is measured in purchase orders rather than task orders on large vehicles; the top parent vehicles show only 10 to 5 task orders each, reflecting RNK International's position as a spot-purchase vendor rather than an anchor on sustained IDIQs.

RNK International's award portfolio spans 1,725 prime and sub awards across 104 distinct federal agencies, with combined potential value of $19.7 million and combined obligated dollars of $29.3 million. Recent activity has averaged 54 awards per year across 2022–2026, with a spike to 56 awards in 2025 and a decline to 20 awards in the first half of 2026 (incomplete year). The vast majority of work is under total small business set-asides. By PSC, the vendor's portfolio clusters on Refrigeration and Air Conditioning Components (410 awards), Space and Water Heating Equipment (235 awards), Air Conditioning Equipment (203 awards), Valves Nonpowered (181 awards), and Fans and Blower Equipment (79 awards); by NAICS, Air-Conditioning and Warm Air Heating Equipment Manufacturing dominates (483 awards), followed by Industrial Valve Manufacturing (181 awards). RNK International competes full-and-open on a material subset of awards, particularly when suppliers are unrestricted by set-aside or when awards cross into civilian agency procurement such as the General Services Administration and the Department of State Bureau of Overseas Building Operations.
