The Cryogenic System（birkett深冷装置）
The majority of the large industrial gas supply companies now supply their gas in its liquefied state, with the gas being turned back to a gas on site, when demand is generated. The liquefaction of gases is often referred to as "cryogenics".
The liquefied gas is stored in a dewar, which is designed to keep heat out of the vessel, whilst maintaining the cryogenic temperature inside the vessel.
There are various elements to a typical dewar: the pressure build circuit, the safety relief system, the economiser circuit and the final "house" supply line. We are able to offer products which can be used in all of the above areas.
Pressure Regulation - several ranges of back pressure and pressure reducing valves are available to regulate pressure in the various parts of the dewar system.
Safety Relief - A full range of safety relief valves and bursting discs are available to protect the dewar from over pressurisation.
Associated Products - Strainers, low temperature cut off valves and isolating valves are also available to compliment the above items.
