Cryogenic storage tanks for LNG are designed and manufactured for all types of bulk, satellite plant and fuel service station applications with the requirements for safe, easy and economical operation.
The Highlights of ISISAN tanks are:
LnV / LnH series tanks are vertical or horizontal, stationary pressure vessels with perlite insulation for storage of extreme cold liquid natural gas, with high quality vacuum level and low evaporation rate.
Low operation costs and additional safety by the economizer circuit, because the boil off gas is routed into the main system via the economizer circuit taken from a top gas connection, which prevents wastage of gas.
In addition to our standard range of tanks, ISISAN can provide you a wide range of tailor made storage solutions up to 300,000lt with a Maximum Allowable Working Pressure of 5 bar or other pressures as required.
ISISAN bulk tanks are designed and manufactured in accordance with and conforming to EC directive PED 97/23/CE and EN 13458 or other national pressure vessel codes as required.
ISISANâ€™s cryogenic tank manufacturing facility is ISO 9000 approved, to assure the best quality in all aspects of our operation.
The support legs used are calculated according to UBC, Eurocode standards to resist high wind and earthquake loads.
Carefully designed stainless steel pipe work to reduce filling operation time. Appropriate bending of stainless steel pipe work means fewer connections, minimizing potential leaks, higher operability and less servicing.
Operational reliability by the mono-bloc pressure building economizer-regulator for easy pressure adjustments.
High quality stainless steel pressure gauge and differential pressure contents gauge are standard with optional switches, transmitter and/or telemetry unit.
High performance safety system with dual relief valves and rupture discs by the diverter valves as standard.
Easily accessible valves and safety relief valve outlets directed away from the operating area, enables safe operation.
Rugged internal supports for safe transportation by road, container or rail.
