Perma-Cyl® MicroBulk Systems

Allowing small and medium volume users to enjoy the benefits of onsite gas delivery, Perma-Cyl MicroBulk Storage Systems provide reliable, efficient and economical solutions for liquid nitrogen, oxygen, argon, CO2, N2O and LNG.

Designed to replace high pressure gas cylinders, Perma-Cyl tanks eliminate:

  • waste and expense of full for empty gas cylinders
  • cylinder change-overs
  • residual gas losses
  • lost or damaged cylinders
  • cylinder inventory management
  • manual handling injuries

Higher Thermal Efficiency

Perma-Cyl tanks are designed to a higher level of thermal efficiency than competitor products, which means it holds its gas contents longer with lower pressure rise. In fact the extraordinary thermal quality of Perma-Cyl tanks limits product losses during extended periods of little, or even no, gas use.

  • Size, pressure and configurations to meet most applications
  • Manufactured in Chart's US, European and Chinese facilities in accordance with all applicable international quality standards and regional codes
  • Suitable for indoor or outdoor installation and operation
  • Capacities from 230 to 7,000 liters (61 to 1840 gal)
  • Top fill float is designed to allow single hose filling without product loss, under normal conditions
  • Automatic shut-off when used in cojunction with Orca™ MicroBulk Delivery System
  • Caster/pallet base depending on model
  • ZX range designed for high pressure, high flow applications
  • Special features for medical gas use
  • Horizontal versions of selected models available
  • Perma-Max™ models for CO2 service
Chart's Build-Your-Own Perma-Cyl® System program enables gas distributors to customize the tank controls to match their customer's application and their business process.
