Product Overview

The RF-391 Series is a Mega SF6 gas handling unit for large-volume SF6 gas service. The published selection range is approximately 200 to 500 kg of SF6 per service operation.

This large RF Series recovery unit is suitable for large GIS and high-voltage SF6 equipment. It is a practical choice for utility-scale gas maintenance, large substations, high-voltage switchgear factories, and SF6 filling stations.

The system offers rich configuration options, including one-button or touch screen control, different vacuum compressor stages, several vacuum pump and Roots pump choices, and storage tank options up to 600 L.

Product Advantages

  • Designed for approximately 200 to 500 kg large-volume SF6 gas handling in GIS equipment
  • Multiple compressor, vacuum pump, Roots pump, voltage, and storage-tank options support project-specific requirements
  • Oil-free compressor and oil-free vacuum compressor help keep recovered gas clean
  • The current published configuration specifies SF6 recovery down to below 0.1 mbar
  • Built-in liquid filling equipment can fill a 70 L cylinder in about 5 minutes
