Thermavant Technologies LLC

Thermavant Technologies LLC, doing business as Thermavant, is a small business manufacturer of advanced thermal management systems for federal space, aerospace, and defense R&D programs, competing as a prime contractor (90% of awards) under total small business set-asides and SBIR vehicles. Based in Columbia, Missouri, and organized as a limited liability company, Thermavant specializes in oscillating heat pipes, cryogenic thermal systems, heat spreaders, and thermal solutions for microelectronics, laser weapon platforms, and satellite applications — technologies it develops and manufactures under NASA and Air Force Research Laboratory SBIR Phase I, II, and III contracts, as well as under direct R&D agreements with defense agencies.

Thermavant's customer concentration reflects a strong Air Force Research Laboratory anchor. The top five funding agencies account for 90% of awards: the Air Force Research Laboratory dominates on potential value ($32.9 million across 18 awards), while NASA's Shared Services Center leads on award count (23 awards, $7.7 million combined potential value). The Department of the Navy (Naval Sea Systems Command and Office of Naval Research), the Department of the Army, and the Department of Defense round out the active set. The Air Force's lead on dollars versus NASA's lead on count reflects Thermavant's mix of large Phase III and direct-R&D contracts with AFRL (ranging from $7.24 million to $8.4 million per award) and smaller Phase I SBIR efforts from NASA (typically $149,000 to $156,000). Representative prime work includes a $8.4 million cost-plus-fixed-fee definitive contract with Air Force Research Laboratory for high-power-density structural heat-spreader development (Phase III SBIR topic AF151-094, completion September 2026), a $7.24 million cost-sharing contract with AFRL for semiconductor processes for oscillating heat pipes (June 2026), a $1.27 million Phase II SBIR contract from the Shared Services Center for large-format ceramic oscillating heat pipes (September 2028), and a $711 thousand DARPA definitive contract for flexible oscillating heat pipes for microelectronics thermal management (July 2027).

Activity has remained steady across the last five years (seven awards in 2022 through six in 2025), with only one award recorded in 2026 to date. Three awards (combined potential value $2.9 million) face ultimate completion within the next twenty-four months and therefore present recompete exposure. In its minority subcontractor role, Thermavant provides oscillating heat pipes, cold-plate thermal mechanical engineering, and copper heat-sink components to Northrop Grumman on DARPA research and Evolved Strategic Satellite Communication programs, to Lockheed Martin on the Digitally Expanded UHF MIMO Optimized Radar (DEUMOR) program, to Raytheon on the Advanced Technology Support Program for Ku-band radar microelectronic capability solutions, and to ManTech TSG-2 on Naval Surface Warfare Center research and development of radar and electronic warfare systems. Thermavant's work portfolio sits almost entirely within SBIR and direct R&D, with top NAICS concentration in Research and Development in the Physical, Engineering, and Life Sciences (42 awards) and top PSC concentration in General Science and Technology R&D Services and National Defense R&D Services.

We design, develop and manufacture custom thermal heat transfer products for government, commerical and consumer end users. We specialize in the Oscillating Heat Pipe (OHP) and other two-phase thermal technologies.
