Product Description
Manual SF6 Recovery System – 600L Negative Pressure Gas Recovery Unit
High-Efficiency SF6 Gas Recovery & Storage System for Switchgear Manufacturers
KSLH-55Y/80/600Y
Product Overview

KSTONE KSLH-55Y/80/600Y is a professional manual SF6 negative pressure recovery unit with 600L liquid storage capacity, specially designed for high-voltage switchgear (GIS) manufacturers and maintenance service providers. Adopting high-pressure refrigeration liquefaction and air-cooled technology, this mobile hand-push type equipment can realize efficient recovery, purification, liquefaction storage and refilling of SF6 gas. It can reduce the residual pressure of SF6 in GIS to 1kPa (absolute pressure), with a purification efficiency of up to 99.99%, which fully meets the industrial application requirements of SF6 gas recycling and environmental protection.

Core Advantages
  • ✅ Ultra-high Recovery Precision – Final recovery pressure ≤-0.1MPa, residual gas is almost completely recovered
  • ✅ Efficient Liquefaction Storage – 600L special liquid storage vessel, maximum storage capacity 600kg, pressure resistance 4MPa
  • ✅ Fast Processing Speed – 1m³ SF6 gas recovery only takes ≤0.15h (depending on interface size)
  • ✅ Integrated Multi-function – One machine for recovery, purification, drying, filtration and refilling
  • ✅ Flexible Mobile Application – Compact structure, hand-push design, suitable for on-site maintenance of HV switchgear
  • ✅ Reliable Quality Certification – ISO9000 certified, stable performance, adapt to industrial on-site working environment

Key Components & Working Principle
Core Configuration

The equipment is equipped with high-performance SF6 compressor (55m³/h), vacuum compressor (80m³/h) and vacuum pump (63m³/h), matching professional drying and filtration system, which ensures the purity of recovered SF6 gas and the stability of the whole machine operation. The 600L high-pressure resistant liquid storage vessel adopts special sealing technology to realize safe and reliable long-term storage of SF6 liquid.

Working Process
  1. Negative Pressure Recovery – The vacuum pump extracts the residual SF6 gas in GIS to the recovery unit under negative pressure condition, with final residual pressure ≤-0.1MPa
  2. Purification & Drying – The recovered gas is filtered and dried by the built-in purification system to remove impurities and moisture, ensuring 99.99% SF6 concentration
  3. Liquefaction Storage – The purified SF6 gas is converted into liquid state by high-pressure refrigeration liquefaction technology and stored in the 600L special vessel
  4. Precision Refilling – The liquid SF6 is vaporized and refilled back to GIS equipment according to the working pressure requirement, with refilling final pressure up to 0.7MPa
