Cryogenic economisers for improved efficiency

Economizers are pressure reducing valves that allow vapour into the fuel line during operation to reduce the pressure inside the tank to the set valve pressure. They are used in cryogenic lines and liquid cylinders, converter applications and vapourisers.

Product description

Due to their small size, economisers are great where cost and spatial restraints are important factors in applications. Their functionality is different from a regulator where the outlet pressure is specifically adjusted.
