What PMT Nuclear does
PMT Nuclear (Preferred Metal Technologies, Inc.) is a privately held specialty manufacturer headquartered in Woodridge, Illinois, that designs, manufactures, qualifies, and tests custom safety-related and non-safety-related HVAC equipment for commercial nuclear power plants. With over 20 years of operating history, the company supplies chillers (screw, centrifugal, and reciprocating), air handling units, air filtration units, heat exchangers, ductwork, dampers, actuators, specialty enclosures, and purpose-built nuclear components such as blow-out panels, pipe penetration boots, and CRD-HCU units to most domestic and many foreign nuclear utilities. Its workforce — including designers, engineers, and quality assurance personnel — works on nuclear projects exclusively.
The company's core technology platform is the NUC-Magnum digital controller, a safety-related qualified chiller controller with +/- 0.5 F chilled water temperature precision, seismic qualification, EMI/RFI testing, and NEMA 4 enclosure options. PMT offers control retrofit services that install the NUC-Magnum controller on existing chillers from any manufacturer, available either as safety-related under its quality assurance program or as a commercial-grade product with nuclear-specific upgrades including cybersecurity enhancements. The company holds NQA-1 2008 Edition certification, 10 CFR 50 Appendix B compliance, ASME Sections I/II/III/IV/VIII/IX, ASME AG-1, ANSI N45.2, NBIC Parts 1/2/3, and multiple ANSI B31 piping code certifications, forming a regulatory barrier that few competitors in the nuclear HVAC space can match.
PMT operates a project-based, direct-to-utility sales model with quote-based pricing, supplemented by 24/7 field services, qualification and testing services, mechanical engineering, and a reverse-engineered spare parts business that positions it as a single-source supplier for legacy nuclear HVAC components. Revenue is derived from one-time equipment sales, recurring spare parts and field service contracts, and an emerging digital retrofit service line. The company maintains affiliations with multiple construction trade unions and participates in nuclear industry trade associations to support installation and field services delivery, and is legally distinct from affiliated entity AMS Mechanical Systems, Inc.
