What Presray does

Presray Corporation is a Wassaic, New York-based specialty manufacturer founded in 1955 that designs and builds custom-engineered critical containment solutions for flood, watertight, airtight, fire, and ballistic protection. The company originated by developing lifting devices for the aerospace industry using large inflatable rubber seals, then applied that expertise beginning in the 1970s to align its quality assurance program with the Nuclear Regulatory Commission and to produce watertight doors and barriers for safety-critical facilities. Presray's products are deployed at more than 20 nuclear power plants worldwide and at major commercial, healthcare, hospitality, and municipal sites including Singapore's Ocean Financial Centre and the Texas Medical Center, with a stated mission of protecting hundreds of businesses, academic, governmental, and civic facilities.

Presray's portfolio is organized around two proprietary seal technologies: Pneuma-Seal inflatable pneumatic seals that deliver redundant watertight protection on multiple sides of an opening, and Type 25 durometer fully-molded neoprene mechanical compression gaskets whose self-tightening design transfers water pressure into downward compression with no air or power required. The lineup spans stackable flood barriers (FastLogs in Light, Standard, and Heavy Duty; CGSL stop logs), hinged and sliding floodgates (FB22, FB33, FB44, FB55, CG11HA, CG3S), watertight doors and hatches (D3C, D3DQA, D3HA, D5B, FB77), NUPIC-certified spent fuel pool gates, UL-rated fire and ballistic doors (45/90/180-minute ratings), pneumatic- and mechanical-seal APR doors for laboratories and cleanrooms, and the HYFLO SCFB automatic self-deploying flood barrier with a documented 100% success record in 2,000+ flood events since 1998. Products are designed to a 2:1 factor of safety and validated at the company's on-site Presray Testing and Training Center, carrying FM Approvals, UL, FEMA, NFIP, U.S. Army Corps of Engineers, and NUPIC 10CFR50 Appendix B certifications.

The company runs a direct enterprise field-sales model with engineering support, handling custom design, shop drawing, manufacturing, installation, inspection, and field repair. Revenue is generated primarily through one-time custom hardware sales complemented by recurring Service & Parts contracts on installed equipment. Presray distributes internationally through three channel partners: Chung Ah Engineering Pte Ltd (Singapore, Thailand, Indonesia, Malaysia), Wierig Industrial Products (Philippines), and PODS Marketing Mix Ltd (Trinidad & Tobago). Presray Corporation has remained privately held since founding, with no disclosed venture capital, private equity, or public market participation, and operates 11-50 employees from its single Wassaic manufacturing and headquarters site.
