Industry: Hydrogen

LH2 Johnston coupling

LH2 Johnston couplings are convenient couplings that link vacuum insulated liquid hydrogen transfer lines to each other and to the end application.

Liquefier for hydrogen

Demaco supplies liquefiers for hydrogen. The Demaco liquefier uses a cryocooler and produces pure liquid hydrogen of the best quality.

Loading Bay

The loading bay makes it possible to load liquid hydrogen quickly and safely on a vessel or truck. Read on for more about the Demaco loading bay.

Loading arm

A loading arm facilitates liquid hydrogen transfer from one tank to another. Continue reading for more about the Demaco loading arm.


Project ESS

The European Spallation Source (ESS) is a Partnership of 13 European Nations committed to the goal of collectively building and operating the world’s leading facility for research by use of neutrons. ESS is going to provide a long-pulsed cold and thermal neutron beam for scientific instruments. The beam is produced by spallation in a tungsten …

Cryo valves

Demaco Cryogenic Valves

Most cryogenic systems include one or more cryogenic valves; these valves effectively manage the flow and quality of liquid gases. These valves are integrated into the piping system, cryogenic dewars, or quality-enhancing products to stop, pass or drain liquid or gaseous agents. Demaco offers three standard valves: Demaco Cryogenic Valve – Manual on/off Demaco Cryogenic …

Demaco Subcooler

In most cryogenic infrastructures, some evaporation of liquid gas occurs. This results in a mixture of gas and liquid, which is not favorable for the infrastructure’s functionality, capacity, and operation. Quality improvement products like a phase separator, degasser, automatic gas vent, and subcooler are widely used in cryogenic engineering for the discharge or re-condensation of evaporated gases. …

Vacuum Insulated Piping

Vacuum Insulated Transfer Lines (VIP)

Rigid- and flexible vacuum insulated transfer line Vacuum Insulated Piping forms the basis of almost every cryogenic infrastructure. The double-walled pipes ensure that cold liquid gases can be safely transported without excessive warming and lose their liquid state, which causes a quality reduction. Transfer lines connect, for example, a vessel to an application or an …
