The new VT range of cryogenic tanks combines safety, flexibility and easy economical operation. The VT series includes 45 models with features industrial gas producers and users have asked for, but could not get until now. Primary among these features is a high performance, standard design with a wide range of options to meet most special needs.

The VT series is designed for long-term storage of liquefied air gases, including nitrogen, oxygen, and argon, as well as carbon dioxide and nitrous oxide. The VT series is available in capacities from 3.000 to 60.000 liters and maximum allowable working pressures of 19, 26 and 37 bar.

IGC's other new series of tanks, the VTC series, provides high-efficiency, economical vacuum-insulated storage of liquefied carbon dioxide or nitrous oxide. All tanks are in accordance with EN, AD-Merkblätter or other national pressure vessel codes, as required. Tanks outside this range are available upon request.

Finally, IGC manufactures customized vertical and horizontal storage tanks with capacities up to 560.000 liters. IGC can also supply vaporizers, vacuum insulated pipeline and other components needed to create a complete "customer" installation.

Benefits of the VT Series

Inner Vessel - stainless steel for cryogenic temperatures with optimized design for lighter weight

Outer Jacket - a combined leg and lifting lug system designed for safe transport, easy lifting and low cost erection using a single crane

Insulation - a proven high quality vacuum-perlite system with molecular sieve adsorber

Piping - stainless steel piping for reliability and long life, ergonomically arranged workplace, flow diagram and gauges at eye level, easily accessible valves and safety relief valve outlets directed away from the operating area

Valves - standard with bronze bodies and screwed connections (other valves, such as stainless steel and/or welded-on are optional)

Pressure Control - an easily adjustable multifunction regulator serves as pressure regulator, economiser and thermal-relief valve. An aluminum pressure building coil is standard

Instrumentation - high quality pressure gauge and differential pressure contents gauge are standard with optional switches, transmitter and/or telemetry unit

Safety - tanks are equipped with dual relief valves with a variety of options, including additional relief valves and/or rupture discs

Pump Options - pump connection with a thermo-siphon is available as an option

Cleanliness - all tanks and their components are cleaned and certified for oxygen service

Outer Finish - choice of two durable corrosion resistant white paints, including a new low VOC paint or a standard 2-stage epoxy-polyurethane paint

Transport - rugged internal supports allow for safe transportation by road, rail or container

Notes:
1) Filling 95% (equilibrium state at 1,013 bar)
2) Fillling 95% (equilibrium state at 10 barg)
3) Based on pressure 100 kPa and 15°C ambient temperature
4) For N2 and Ar stated rates to be multiplied by: N2=0,88 / Ar=1,01
5) Stated rates are for short term withdrawal (up to 3 hrs) at tank pressure 10 barg
6) Stated rates are with the 6 kW electrical heater at tank pressure 15 barg
7) Tanks with thermosiphon are approx. 790 mm higher
8) In case of container transport 200 mm shorter
9) Design and specifications are subject to change without prior notice.
