High-Pressure Liquefaction · Oil-Free Compressor · Automatic PLC Control · Regenerative Drying & Filtration
The KSLH-6WYTO3Z Fully Automatic SF₆ Gas Recovery, Vacuuming & Filling System is a mobile SF₆ gas handling unit designed for the recovery, high-pressure liquefaction, vacuum evacuation and refilling of SF₆ gas used in GIS, circuit breakers and other SF₆-insulated electrical equipment.
The system combines a 6 m³/h oil-free SF₆ compressor, high-pressure liquefaction technology, a 25 m³/h vacuum pump, regenerative drying and filtration, a 10-inch PLC touchscreen and an external weighing system into one integrated unit.
With fully automatic control, air-cooled operation and a mobile trolley design, KSLH-6WYTO3Z is suitable for both power equipment manufacturers and on-site SF₆ service and maintenance applications.
The KSLH-6WYTO3Z is equipped with a 10-inch PLC touchscreen for centralized control and monitoring.
The touchscreen displays the operating process and key parameters, helping operators manage SF₆ recovery, vacuum evacuation and filling operations with less manual intervention.
The system uses a high-pressure liquefaction design to recover SF₆ gas and liquefy it for efficient storage in an external cylinder.
The maximum discharge pressure of the oil-free SF₆ compressor reaches 50 bar, providing sufficient pressure for high-pressure SF₆ liquefaction.
SF₆ Gas → Compression → Filtration & Drying → High-Pressure Liquefaction → Storage Cylinder
The system uses a dedicated oil-free SF₆ compressor with a theoretical displacement of 6 m³/h and a maximum discharge pressure of 50 bar.
The oil-free compression design helps prevent lubricating oil from entering the SF₆ gas circuit during recovery.
This is particularly suitable for applications where maintaining the quality of recovered SF₆ gas is important.
An integrated drying and filtration system helps reduce moisture and particulate contamination during SF₆ gas recovery.
The drying filter uses vacuum heating activation regeneration, allowing the filter to be regenerated and reused.
The system is designed to achieve a recovered SF₆ moisture level of:
≤60 ppm/V
The external weighing system provides a weighing range of 0–120 kg.
Operators can monitor cylinder weight directly through the touchscreen and use:
This allows the operator to control the amount of SF₆ gas transferred during filling and helps prevent overfilling.
The system is equipped with a 25 m³/h vacuum pump with an ultimate vacuum of ≤1 mbar.
The vacuum system can be used to evacuate air and moisture from SF₆ equipment before gas filling.
The specified ultimate vacuum of the overall vacuum system can reach:
≤1 mbar
KSLH-6WYTO3Z adopts an air-cooled design, eliminating the need for an external cooling-water source.
The mobile trolley structure is equipped with swivel and fixed wheels for convenient movement and positioning during field service.
This makes the system suitable for:
An SF₆ gas recovery system is specialized equipment used to safely recover, store and reuse sulfur hexafluoride (SF₆) gas from electrical equipment during maintenance, installation and servicing.
SF₆ is widely used as an insulating and arc-quenching medium in:
During maintenance, SF₆ gas should be recovered rather than released directly into the atmosphere.
A complete SF₆ gas handling system can perform several essential operations, including:
Recovery → Filtration & Drying → Liquefaction → Storage → Vacuum Evacuation → Refilling
The KSLH-6WYTO3Z integrates these core functions into one mobile system.
SF₆ gas is extracted from the electrical equipment and transferred to the recovery system.
The 6 m³/h oil-free SF₆ compressor compresses the recovered gas.
During the recovery process, the gas passes through the integrated drying and filtration system.
The system helps remove:
The regenerative drying filter can be activated through vacuum heating for repeated use.
The compressed SF₆ gas is further pressurized for high-pressure liquefaction.
The liquefied SF₆ can then be transferred to an external storage cylinder.
After maintenance or before refilling, the vacuum system evacuates air and residual gases from the electrical equipment.
The vacuum pump provides a pumping speed of:
25 m³/h
with an ultimate vacuum of:
≤1 mbar
After the equipment has been evacuated, SF₆ gas can be transferred from the storage cylinder into the electrical equipment.
The external weighing system continuously monitors the cylinder weight.
The automatic shutdown function can stop the filling process according to the preset operating conditions.

The integrated 10-inch PLC touchscreen provides a centralized interface for operating and monitoring the SF₆ gas handling system.
The main interface provides an overview of the operating process and system status.
The settings interface allows operators to configure operating parameters and control functions.
The operation page provides real-time information during SF₆ recovery, vacuum evacuation and filling.
The KSLH-6WYTO3Z can be used for SF₆ gas recovery, vacuum evacuation and refilling during GIS inspection and maintenance.
The system supports SF₆ recovery and refilling operations during circuit breaker maintenance and servicing.
The mobile air-cooled design makes the unit suitable for on-site SF₆ gas handling at substations.
The vacuum system can evacuate air and residual gases before SF₆ filling during installation and commissioning.
Recovered SF₆ can be liquefied under high pressure and transferred to external cylinders for temporary storage and subsequent reuse.
