Moving Forward. One solution at a time.
Our Story
For almost six decades, CPC-Cryolab has been one of the most trusted names is the industrial gas and cryogenic valve business.
CPC-Cryolab was founded in Florida to support the Space Program and the world’s first commercial size liquid hydrogen plant. The plant was built in Palm Beach County and CPC designed and manufactured all of the valves, filters, piping and transfer connections used in the facility.
In 2000, CIRCOR acquired the Rockwood-Swendeman line of cryogenic safety relief valves from Rockwood Systems of Portland, Maine. This industry valued line of SRV’s helped to further compliment the growing product line CPC-Cryolab has to offer.
In 2021 CPC-Cryolab became became a part of the Marshall Excelsior Company (MEC) family of companies.
A large number of our product offerings are used in liquid hydrogen and liquid helium services. We are known as the world leading manufacturer of liquid hydrogen and liquid helium cryogenic components and equipment. We pride ourselves with the largest and most diverse family of products supporting the hydrogen and helium markets with; vacuum jacketed filters, valves, hoses, piping systems, manifolds and transfer connections available in the industry.
