What Hyperbaric Modular Systems does

Hyperbaric Modular Systems, Inc. (HMS) is a privately held US manufacturer founded in 1971 (originally as Sub-Sea Surveyors, later Saturation Systems and OxyHeal Medical Systems before being acquired in 2018 and rebranded to its current form) and headquartered at 1663 Pacific Rim Court, San Diego, CA. The company designs, manufactures, installs, and services custom hyperbaric chamber systems for four end-markets: clinical hyperbaric oxygen therapy (HBOT) in hospitals and medical centers; military and commercial diving (recompression chambers, diving simulators up to 600m depth, NAVSEA-compliant Navy systems); tunneling and compressed air work (TBM manlocks, transfer-under-pressure shuttle systems, saturation systems); and test/research applications (blast-rated pressure test chambers up to 155 bar / 156 ATA). Core product families are the HMS 5000 (rectangular, 6-20 patients), HMS 4000 (cylindrical/semi-cylindrical, 6-18 patients), and HMS 2000 (vertical-cylindrical, 3-4 patients, patent-protected), all certified to PVHO standards and FDA-cleared for medical use.

HMS's technology stack combines ASME-certified pressure vessel fabrication, ISO 9001:2015 quality management, NFPA-compliant fire suppression, HMI-based chamber control systems, CCTV/intercom/AV systems, and multi-level O2 sensing to deliver multiplace chambers that permit inside-attendant patient care not achievable in monoplace units. The company holds NAVSEA TS500-AU-SPN-01 / UFC 4-159-01N compliance for Navy applications and NATO STANAG flanges for allied interoperability, and has demonstrated product durability with systems operating continuously for 20+ years in clinical use (UCSD's 1983 system still in operation 35+ years later).

HMS operates a direct enterprise sales model with no reseller channels, marketing its products through its corporate website, industry conferences (e.g., UHMS training course hosting), and direct engineering-led engagement with hospital procurement, military contracting officers, and tunneling project owners. Revenue is generated primarily through one-time custom engineering and installation contracts (the largest disclosed being a US Navy IDIQ contract for up to 20 pressure test chambers) supplemented by recurring life-cycle support, servicing, maintenance, and overhaul contracts. The company is led by President & CEO Adrian Garay and operates with a headcount of 11-50 employees.

Revenue model

1. Custom Hyperbaric Chamber Design, Manufacturing & Installation: HMS designs, manufactures, and installs custom hyperbaric chamber systems tailored to each client's specific goals, space, and budget. Revenue is generated through one-time custom engineering contracts for medical, diving, and research applications. The company also performs final installation and life cycle support.
2. Life Cycle Support, Servicing & Maintenance: Post-installation servicing and maintenance contracts for hyperbaric chamber systems. HMS provides technical support, operator training, and biomedical maintenance personnel training to ensure long-term reliable operation of installed systems.
3. System Upgrades and Overhauls: HMS specializes in upgrades and overhauls to existing hyperbaric systems, including modernization of older systems (e.g., containerized diving systems for Department of National Defence Canada).
4. Navy IDIQ Contract (US Navy): Under a three-year IDIQ contract with the US Navy, HMS delivers pressure test chambers (HMS-TESTCOM 300/76) up to a maximum of 20 units. This represents a government procurement revenue stream with defined task orders.

Core offering

Hyperbaric Modular Systems, Inc. (HMS) designs, manufactures, installs, and maintains custom multiplace hyperbaric chamber systems for clinical hyperbaric oxygen therapy (HBOT), military and commercial diving, tunneling and compressed air work, and high-pressure test and research applications. The company offers four product families (HMS 5000 rectangular, HMS 4000 cylindrical/semi-cylindrical, HMS 2000 vertical-cylindrical, plus test/research, diving, and tunneling lines) and provides full lifecycle support including operator and biomedical maintenance training, system upgrades, and overhauls.

Product overview

Hyperbaric Modular Systems (HMS) designs, manufactures, installs, and maintains hyperbaric chamber systems across four product categories: Medical HBOT Systems (HMS 5000 rectangular, HMS 4000 cylindrical/semi-cylindrical, HMS 2000 vertical-cylindrical), Test and Research Chambers, Diving Systems & Simulators, and Tunneling Technology. The HMS 5000 and HMS 4000 families are multiplace medical chambers for hospitals treating 6-20 patients with inside attendant capability. The HMS 2000 is a vertically-oriented multiplace chamber serving 3-4 patients in a smaller footprint. Diving products include Navy-standard recompression chambers, TRCS, containerized systems, and diving simulators up to 600m depth. Tunneling products include TBM manlocks, shuttle systems, and saturation systems. The company also produces the HMS-TESTCOM 300/76 pressure test chamber for government and military calibration applications.
