• 99.99% SF6 Gas Recovery Efficiency

• One-Key Automatic Operation

• Integrated Gas Purification System

• Designed for Power Utilities and Switchgear Manufacturers

The SF6 Gas Recovery System is a specialized equipment designed for recovering, purifying and recycling sulfur hexafluoride (SF6) gas used in high-voltage electrical equipment.

SF6 gas is widely used in:

• Gas Insulated Switchgear (GIS)

• High Voltage Circuit Breakers

• Gas Insulated Transmission Lines

• Substation Equipment

During maintenance, repair or decommissioning of electrical equipment, the SF6 gas must be safely recovered and purified to prevent atmospheric emissions and ensure environmental compliance.

The Kstone Fully Automatic SF6 Recovery System provides efficient gas recovery, purification and storage in one integrated unit, helping utilities and equipment manufacturers manage SF6 gas safely and efficiently.

High Recovery Efficiency

The system achieves up to 99.99% SF6 gas recovery rate, minimizing gas loss and reducing operating costs.

Fully Automatic Operation

Equipped with an intelligent PLC control system, the unit enables one-key automatic recovery, purification and refilling operations.

Integrated Gas Purification

Advanced filtration and drying technology removes:

• Moisture

• Oil

• Solid particles

Ensuring the recovered SF6 gas meets reuse standards.

Compact & Mobile Design

The system features a compact structure with mobile wheels, making it suitable for on-site substation maintenance.

High Reliability

Built with industrial-grade compressors and components designed for long-term continuous operation.

Movable casters

Filtration and drying system

Solenoid valves

PLC with touchscreen, internal piping and external connecting pipes

Recover and recycle SF6 gas during inspection and maintenance of GIS equipment.

Used during repair and testing of high-voltage circuit breakers.

Widely used by utilities and service providers for SF6 gas handling.

Manufacturers use the recovery unit during testing and gas filling processes.

The recovery process includes several stages:

1. Extraction of SF6 gas from electrical equipment
2. Gas compression and cooling
3. Filtration and purification
4. Liquefaction and storage
5. Refilling into equipment if required

The system ensures efficient gas recycling while preventing environmental emissions.

Optional components include:

• Gas storage cylinders

• Digital gas purity analyzer

• Vacuum pump upgrade

• Touch screen control system

• Mobile service cart

Customized configurations are available for different applications.

1. After startup, the screen displays manual, automatic, and parameter setting modes.
2. Parameter settings cover various control and protection points, which are pre-configured at the factory and may be slightly adjusted during on-site commissioning.
3. Automatic operation modes include:
   1. Vacuum pumping
   2. Recovery
   3. Gas charging
   4. One-key full-process operation option
