Heritage
Cryogenic roots. Modern manufacturing scale.
FWM's foundation is cryogenic heat-transfer manufacturing. For decades, FWM built vaporizer products supplied through established industrial gas and cryogenic equipment channels. Today, FWM brings that manufacturing experience direct to OEMs, distributors, and end users.
Cryogenic products demand attention to pressure, cleanliness, material compatibility, heat transfer, testing, documentation, and long-term reliability. Those same disciplines carry into the OEM side of the company, where FWM supports repeatable aluminum and stainless assemblies built to customer requirements.


Quality & Trust
Quality and documentation are part of the product.
FWM supports customer-specific quality and documentation requirements across vaporizer products and OEM programs. Depending on the project, documentation can include material test reports, certificates of conformance, inspection records, pressure-test records, leak-test records, dye penetrant inspection reports, cleaning documentation, weld maps, and first-article documentation, where specified.
Quality is not a final step. It starts with engineering review and continues through material receipt, production routing, in-process checks, final inspection, documentation, packaging, and shipment. Customer drawings and specifications are treated as confidential manufacturing records.
Questions
Common questions from buyers.
FWM manufactures cryogenic ambient-air vaporizer products and heat-transfer equipment, and produces repeatable aluminum and stainless assemblies for OEM and build-to-print programs. Work is performed on one integrated floor in Hudson, New Hampshire.
FWM is a manufacturer. Cutting, machining, forming, welding, assembly, inspection, packaging, and shipment are handled in-house rather than outsourced through a brokerage model.
Documentation scope is matched to the program and confirmed during engineering review. Depending on requirements it can include material test reports, certificates of conformance, inspection and dimensional records, weld maps, first-article documentation, and test records such as pressure, leak, and dye penetrant.
Yes. FWM supports moving repeatable aluminum and stainless programs to a single U.S. floor, beginning with drawing review and a manufacturability assessment to confirm fit before production.
Send drawings, specifications, or application details through engineering intake. FWM reviews the requirement, confirms whether it is a fit, and identifies the next step. NDA-first review is available on request.
