Kendall Holdings LTD.

Kendall Holdings LTD, doing business as Phpk Technologies, manufactures cryogenic and high-vacuum equipment and components for federal agencies as a prime contractor (94% of recent awards), with a customer concentration heavily anchored in NASA facility operations and a smaller defense presence routed through the Navy Office of Naval Research. The company is a for-profit limited liability corporation based in Columbus, Ohio, and competes predominantly in unrestricted (full-and-open) federal markets, with occasional small-business set-asides; recent awards span Total Small Business and sole-source procurement vehicles.

Phpk Technologies' capability portfolio centers on specialized aerospace cryogenic hardware: vacuum-jacketed flex hoses rated for liquid hydrogen and liquid oxygen, helium compressors and cryopump systems, propellant tanks with integrated heat exchangers, LOX and LH2 offloading components, and replacement parts and rebuild services for CVI cryogenic equipment. Representative recent work includes a $57,957 Total Small Business purchase order from NASA's Shared Services Center (awarded July 9, 2026) for six vacuum-jacketed flex hoses supporting the RS25 rocket engine test facility for the Artemis program, a $139,110 order (July 7, 2025) for new and rebuilt cryopumps and spare parts, a $224,170 sole-source order (April 28, 2023) for liquid hydrogen components at the Stennis Space Center, and a $236,860 order (August 9, 2023) for cryopump spare parts and equipment rebuilds. The company also delivers helium compressor rebuilds, custom propellant tanks, and liquid nitrogen hose assemblies to support NASA launch operations and test infrastructure.

Customer concentration clusters at NASA: the Shared Services Center (34 awards, $2.9 million combined potential value) dominates both award count and dollars within the 61% coverage tier, followed by the Glenn Research Center (19 awards, $1.4 million) and the Kennedy Space Center (9 awards, $939 thousand). The Navy Office of Naval Research represents the largest defense customer (6 awards, $2 million), including a $76,800 order (August 8, 2023) for a CRYOPUMP SYSTEM BIG BLUE and a $123,940 order (January 11, 2024) for CVN 73 vacuum-jacketed lines. The National Institute of Standards and Technology rounds out the top five customers with smaller technical-service orders. The top customers by award count and by potential value rankings diverge moderately — ONR's higher average order value ($2 million across six awards) versus the Shared Services Center's higher volume (34 awards at lower unit values) — signaling a mix of recurring consumables and larger systems work.

Activity has been episodic: two awards in 2022, nine in 2023, then three in 2024 and three in 2025, with four awards in 2026 through mid-July. The company faces minimal recompete exposure in the next twenty-four months, with only three awards (combined potential value $172 thousand) reaching ultimate completion within that window. Phpk Technologies subcontracts on space-program infrastructure work: two sub awards under Bechtel National (2021, 2023) for equipment skids and pipe spools supporting the NASA Space Launch System Mobile Launcher 2 design and construction, and two sub awards on unnamed primes for Johnson Space Center engineering and science directorates (cryogenic service valves and chamber piping bayonets, 2023–2025).

The vendor's award portfolio spans NAICS codes centered on valve and pipe fitting manufacturing (332996, 332997, 332911) and compressor/pump manufacturing, with dominant PSC categories in compressors and vacuum pumps (29 awards) and laboratory equipment and supplies (15 awards). Combined potential value across all 121 awards stands at $19.6 million, though obligated spend ($26.2 million) exceeds that figure, indicating downward repricing or order consolidation on some awards. The company has maintained continuous federal engagement since SAM registration in 2004, with the source data extending back to 2004 and reflecting a specialized manufacturer role that recurs across NASA test facilities and Navy shipbuilding programs.
