Perma-Cyl (LN2, AR, CO2)

When filled by the MicroBulk Truck, the Perma-Cyl vessel is designed to have an actual fill-time of three minutes or less (smaller models) with zero losses under normal conditions. The vessel will allow liquid to be held for long periods without venting, limiting product losses during periods of nonuse and allowing you to take advantage of the same benefits that large consumers like laser manufacturers and biotech firms enjoy.


  • Typical product savings of 20%
  • Very low NER/product loss
  • Fast, automatic fills utilizing the MicroBulk delivery system
  • Unique auto shut-off feature allows remote filling with wall box and piping
