SF6 Recovery Systems

SF6 Recovery Systems

SF6 recovery systems are used in combination with leak testing equipment for Switch gears. Switch gears are typically Gas Insulated with sulfur hexafluoride (SF6) which reduces arcing when the circuit breaker is activated.

SF6 recovery system enables the machine to empty a previously filled Product from gas. Concern for the environment is a top priority in the design, manufacture and operation of our products. 

The recovered gas is controlled and collected as clean or dirty. Clean gas can be used for filling of new Products.


SF6 Zero outlet system

SF6 Zero outlet ensures that all remaining SF6 in tools, hoses, and pipes are recovered after each filling of the Product. The recovered gas are then available for reuse. This ensures that remains of SF6 is not evacuated and let out into the environment. 

Characteristics of SF6


  • Highly potent greenhouse gas
  • Chemical Inertness
  • Thermal Stability
  • Non-toxic
  • Non-corrosive
  • Ability to regenerate
  • High dielectric and breakdown strength
