Liquid nitrogen plant (supply of liquid nitrogen -196oC): There are two LN2 plants operated by the group on a round the clock basis producing approximately 200,000 lites of LN2 per annum. Possible applications of LN2- (i) shrink fittings, (ii) expansion joints, (iii) cryo surgery, (iv) cryo treatment of tools, (v) cryo grinding etc Liquid helium plant (supply of liquid helium -269oC): There are two LHe plants operated by the group on a round the clock basis producing approximately 50,000 litres of LHe per annum. LHe may be used as refrigerant for MRI machines. Helium leak detection facility: Leak detection of pressure and vacuum vessels up to 1x10-7 mbar lt/sec
