The LN series are the latest 'water-cooled' liquid nitrogen generators from SLS. Utilising the reliable and efficient PSA technique of separating Nitrogen and Oxygen is used to produce high quality Nitrogen gas which is then liquified using our powerful cooling systems.

The liquid nitrogen is stored within a suitable sized vacuum insulated tank and the product can be dispensed using a 1.5 metre vacuum insulated hose provided. Other options of dispense methods are available on request.

  • Water cooled to ambient temperatures up to 52°C
  • Internal air compressor
  • Nitrogen produced using out own PSA nitrogen generator
  • LN2 at 99% purity
  • Nitrogen injection system for pre-cooling of gas prior to liquefication
  • 50L LN2 storage dewar
  • All cryogenic parts are vacuum insulated
  • Colour touch screen control
  • Small footprint
  • Low noise
