Cryogenic Vessel is essentially a double walled cylindrical tank, annular
space between inner and outer vessel is filled with insulating material and
evacuated to a high vaccum to achieve minimum evarporation losses. The cold
converter is fitted with pressure building arrangement with automatic
pressure build - up regulator.
Design of cryogenic equipment like vessels is compact, sturdy and easy to
operate. Top end liquid filling reduces the pressure inside the tank and
pressure increases in bottom filling. Pressurizing system enables operator
to increase the pressure during liquid unloading to tanks or gas line
vaporizers. By regulating the opening of both top and bottom filling valves,
there is no significant change of pressure during liquid delivery. This
results in constant liquid supply to vaporizer.
Storage at temperature upto (-196°C) ranging from 200 ltrs to 1,50,000
ltrs with option of low and high pressure Cold converters are used to allow
the supply pressure pipe line networks after gasification in atmospheric
heat exchangers, storage tanks supply networks or tanks of smaller capacity
for low liquid temperature directly.
