Kool Radiator Service Inc.

Kool Radiator Service Inc., doing business as Kool Radiator & AC SVC, supplies heating, ventilation, air conditioning, and thermal management components to the Department of Defense as a Service-Disabled Veteran-Owned Small Business prime contractor across 663 federal purchase orders and indefinite delivery contracts. The vendor is a for-profit, Michigan-based SDVOSB and VOSB with federal contractor registration dating to 2004, competing on full-and-open and SDVOSB set-aside bases.

The company's capability footprint centers on rotary compressors, refrigeration components, vehicle heaters, radiators, air conditioning units, hose assemblies, heat exchangers, and related HVAC parts and subassemblies for military fleet maintenance. Recent representative work includes a $251,617.24 delivery order from the Defense Logistics Agency Land and Maritime for rotary compressors under a $2.29 million SDVOSB IDC (awarded December 2023, completion May 2025); a $143,697.84 SDVOSB set-aside purchase order to DLA Troop Support Construction and Equipment for 132 refrigerant compressors (December 2023); a $76,007.04 SDVOSB set-aside purchase order to DLA Land and Maritime for 32 air cooler units (December 2023); and a $74,955.14 full-and-open purchase order from DLA Land and Maritime for 26 vehicle heaters (May 2024). Work spans components ranging from sub-hundred-dollar fasteners to large assembly procurements.

Customer concentration is extreme and single-source dependent: DLA Land and Maritime alone accounts for 321 awards (48% of the prime portfolio) and $20.1 million (83% of combined potential value). DLA Troop Support Construction and Equipment ranks second with 175 awards and $2.5 million. The remaining awards scatter across DLA Aviation, DLA Troop Support Hardware, and Army Materiel Command offices. This concentration reflects Kool Radiator's strategic positioning as a preferred supplier within DLA's vehicle maintenance supply chain rather than diversified agency exposure.

Kool Radiator holds two active indefinite delivery vehicles with DLA Land and Maritime: a $7 million IDC awarded December 2020 (SPE7LX21D5008) with 26 delivery orders totaling $2.2 million, and a $2,289,181.20 SDVOSB set-aside IDC awarded December 2023 (SPE7LX24D5002) with eight delivery orders totaling approximately $1.1 million. A third, newer vehicle is a $250,000 single-award SDVOSB hose assembly IDC awarded February 2025 (SPE7M425D60DE). All work is performed at the contractor's Southgate, Michigan facility.

Activity has declined year over year across the five-year window: from 41 awards in 2022 to eight awards in 2026 (partial year). Only ten awards with combined potential value of $140,000 face ultimate completion within the next twenty-four months, signaling modest near-term recompete exposure relative to the installed base. Red DOT Corporation appears in the source as a recurring subcontractor supporting fulfillment of larger delivery orders for mobile HVAC components, though no formal teaming arrangement is described.

The vendor competes on a mix of full-and-open and SDVOSB set-aside designations. Set-aside work centers on the newer $2.29 million IDC and discrete SDVOSB purchase orders; the bulk of the portfolio, however, flows through competitive full-and-open awards under the larger $7 million IDC. The NAICS and PSC concentration reflects the core capability: Other Motor Vehicle Parts Manufacturing dominates the NAICS footprint (78 awards), followed by Air and Gas Compressor Manufacturing (66 awards) and Rubber and Plastics Hoses and Belting Manufacturing (43 awards); PSC-level concentration tracks to Refrigeration And Air Conditioning Components (119 awards), Compressors And Vacuum Pumps (62 awards), and Hose And Flexible Tubing (44 awards). Kool Radiator operates as a pure prime contractor—all 663 awards are prime awards with no subcontract footprint in the source data.
