At CPC-Cryolab, we lead the industry in manufacturing cryogenic components for liquid hydrogen and helium services. Our extensive product line includes vacuum jacketed filters, valves, hoses, piping systems, manifolds, and transfer connections. With tens of thousands of our valves and equipment in active hydrogen service globally for over 35-40 years without incident, we're committed to providing highly engineered, long-term solutions that prioritize performance, safety, and environmental responsibility.


For more than six decades, CPC-Cryolab has been one of the most trusted brands in the industrial gas and cryogenic valve industry.


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 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 SRVs helped further complement the growing product line CPC-Cryolab offers.


In 2021, CPC-Cryolab became a part of the Marshall Excelsior Company (MEC) family of companies, and was moved to a new facility in Tampa, Florida. This has provided the additional capacity needed to reintroduce to the market 20+ product line offerings while also becoming more aggressive with new product development.

Today, CPC-Cryolab continues to produce state-of-the-art equipment while developing new technology for the cryogenic and industrial gas industries.

The rocket program started when the first military implications of cryogenic technology were developed by the Germans in 1942 with the launching of the first V-2 weapons system.

It is estimated that approximately 4,300 V-2 rockets pounded allied forces during World War II between 1944 and 1945.

After the war, the US Army began testing V-2's at their Ordnance Proving Grounds in White Sands, NM for research purposes.

In the course of the next five years, high-altitude launches and data retrieval would support congressional approval for the development of intermediate and intercontinental range ballistic missiles for national defense.



Our Tampa facility has over 20,000 square feet containing state-of-the-art equipment, processes, and employees working on a friendly, respectful, and safe environment that ensures our products and services continuously meet or exceed our customers’ expectations and regulatory requirements.
