It is a cryogenic fluid
that can cause rapid freezing on contact with living tissue.
Air Liquide (Paris:AI) announced on Wednesday the signing of several contracts for the supply of cryogenic equipments for the propulsion of the future European launcher Ariane 6, as well as for the design and production of the cryogenic fluid
systems of the new Ariane Launcher System (ELA4) of the Guiana Space Centre.
The cryogenic fluid
is delivered in bottles under a compression of 6 MPa in liquid condition.
Liquid nitrogen is a commonly used cryogenic fluid
, used in food freezing and preservation, plastic and rubber grinding, inerting and blanketing, heat treating atmospheres, and tire inflation.
Once upon a time Mr Freeze was dedicated scientist Dr Victor Fries, a home-loving boffin who went violently off the rails after his wife became terminally ill and he fell into his own vat of cryogenic fluid
For bending tests, samples were immersed in cryogenic fluid
(nitrogen) and quickly (no longer than 5 seconds) placed on the same device that was used for bending at room temperature on the INSTRON testing machine.
The portable unit stores 15-liters of cryogenic fluid
in its dewars reservoir, gasifies it, and delivers 40 [ft.sup.3]/hr at temperatures to -180[degrees]C (-292[degrees]F).
The SV91 series of valves provide maximum cryogenic fluid
throughput with minimum pressure drop.
