mobilefor gaseous and liquid SF6 storagefor SF6 gas recovery

The UHV-625 SF6 gas recovery, filling and storage tester is a mobile specialist unit for recycling, purifying, filling and storing SF6 used in SF6-insulated electrical equipment. It supports vacuuming, charging, purification and recovery operations and integrates compressor, vacuum and filtration systems in a compact hand-push chassis.

Features

• Integrated adsorption-filter system removes SF6 impurities: moisture, decomposition products, oil and particles.
• Compact integrated design for easy on-site movement and operation (hand-push mobile chassis).
• High-efficiency, low-maintenance three-stage filter system to ensure recovered SF6 quality.
• Built-in phase protector to avoid phase-reversal errors; quality-brand electrical components used.
• Durable casters and protective coating to ease transport and reduce maintenance.
