Our areas of expertise
CEPHI designs and manufactures gas vaporizers for cryogenics and heaters. The company offers atmospheric or tank vaporizers with coils, curved tubes and CEPHI Diaphragm® Tablecloths.
CEPHI has been CEFRI certified since 2002. The company carries out numerous projects for this sector and carries out, manufactures and installs various studies and realizations.
Test and research centers
The design office provides management and business follow-up, advises and assists clients in the definition of needs. He is the guarantor of the adequacy between the expected client and the CEPHI deliverables.
Successfully completed projects
We offer complete solutions: design by our design office, quality manufacturing and on-site installation.
Nitrogen vaporizer 15 000 nm³-h with water at 20°CCryogenics
Design and construction of an O2 vaporizer with a capacity of 8,000 Nm³/h and an operating pressure of 30 bar g using a steam supply at a pressure of 16 bar g.Cryogenics
Temperature-controlled table with its control panel
Study, realization and installation of 16 thermoregulated tables. Each one is composed of a table with integrated exchanger, a control panel and a control cabinet. Each table combines mechanical resistance and heat exchange requirements. We made a prototype and performed all the validation tests before manufacturing the last 15 tables.Research and development center
