Product Description
KSLHRY-18Y/20-63-200MZ(415V) SF6 Gas Recovery Device
High-Pressure Liquefaction SF6 Gas Recovery System with 600L Storage Tank

The KSTONE KSLHRY-18Y/20-63-200MZ(415V) SF6 Gas Recovery Device is a heavy-duty SF6 gas handling system designed for the recovery, storage, vacuum pumping, filling and treatment of sulfur hexafluoride (SF6) gas from GIS, circuit breakers and other SF6-insulated electrical equipment.

Using a high-pressure liquefaction recovery method, the system compresses SF6 to a high pressure and converts it into liquid form for efficient storage. It integrates an SF6 compressor, vacuum pump, 600L storage tank, filtration system and drying system into one mobile unit.

With PLC touch-screen control, air cooling and a 600L storage capacity, this SF6 gas recovery system is suitable for electrical equipment manufacturers, substations, power utilities and SF6 maintenance applications requiring high-capacity gas handling.


Key Features
High-Pressure Liquefaction Recovery

The SF6 compressor uses high-pressure liquefaction technology to convert recovered SF6 into liquid form for efficient storage and cylinder filling.

600L SF6 Storage Capacity

The integrated 600L storage vessel supports both gas and liquid SF6 storage and provides sufficient capacity for large-scale SF6 recovery operations.

Multi-Function SF6 Gas Handling

One system integrates:

  • SF6 gas recovery
  • SF6 gas storage
  • Vacuum pumping
  • SF6 gas filling
  • SF6 cylinder filling
  • Gas filtration
  • Gas drying
Automatic PLC Control

The PLC touch-screen interface provides an intuitive control system with dedicated operating modes for vacuum pumping, recovery, filling and cylinder filling.

Self-Regenerative Drying System

The built-in drying filter uses vacuum heating activation regeneration, allowing the drying system to be regenerated for repeated operation.

Air-Cooled and Mobile Design

The system uses air cooling and does not require an external water source, making it suitable for field service and maintenance operations.

SF6 Gas Treatment

During the recovery process, the integrated filtration and drying system helps remove moisture and solid particles from recovered SF6 gas.


Main Functions
SF6 Gas Recovery and Storage

The system recovers SF6 gas from electrical equipment and stores it in the integrated 600L storage vessel. High-pressure liquefaction improves storage efficiency.

Vacuum Pumping

A dedicated vacuum pump is provided for evacuating SF6 electrical equipment before gas filling or commissioning.

SF6 Gas Filling

Stored SF6 can be transferred back to switchgear through the filling system. The filling pressure can be controlled through the pressure-reducing valve.

SF6 Cylinder Filling

The high-pressure compressor allows recovered SF6 to be transferred into external SF6 cylinders.

SF6 cylinder filling is a technical operation and should only be performed by trained personnel following applicable safety procedures.

Filtration and Drying

The recovery circuit incorporates filtration and a regenerative drying system to help maintain the quality of recovered SF6 during handling.

Working Principle

The KSLHRY-18Y/20-63-200MZ(415V) combines an SF6 compressor, vacuum pump, storage vessel, filtration system, drying system, valves and measuring instruments.

During SF6 recovery, the compressor increases the pressure of the recovered gas. Based on the pressure-temperature characteristics of SF6, the gas is liquefied under high-pressure conditions and stored in the 600L storage vessel.

At the same time, the filtration and drying system helps remove moisture and solid particles during gas handling.

The system can subsequently use the stored SF6 for gas filling or transfer SF6 into external cylinders through the high-pressure filling circuit.


PLC Automatic Control

The PLC touch-screen control system provides dedicated operating modes for different SF6 handling procedures.
