Product Description
Fully Automatic SF₆ Service Cart for Recovery, Vacuuming & Charging – KSLH-30WY/20-63-300MZ
Integrated SF₆ Recovery, Vacuuming, Charging, Storage & Gas Drying System with 300 L Storage Vessel
Product Overview
The KSLH-30WY/20-63-300MZ Fully Automatic SF₆ Service Cart is an integrated SF₆ gas handling system designed for the recovery, vacuuming, charging, storage, cylinder filling, and drying of SF₆ gas during the manufacturing, installation, commissioning, and maintenance of SF₆ electrical equipment.
The system adopts a high-pressure liquefaction principle. During SF₆ recovery, the gas is compressed to a higher pressure and liquefied for efficient storage or transfer into gas cylinders. A built-in filtration and drying system helps remove moisture and contaminants from the recovered SF₆ gas.
Equipped with a PLC touch-screen control system, the service cart provides automatic operating modes for vacuuming, SF₆ recovery, balanced charging, and compressor-assisted charging. The process flow and operating status can be displayed directly on the touch screen, simplifying operation and reducing manual intervention.
The system uses an air-cooled design and a mobile hand-push configuration, allowing operation without an external water source.
With a 300 L storage vessel, a 30 m³/h SF₆ compressor, and a 63 m³/h vacuum pump, the KSLH-30WY/20-63-300MZ is suitable for professional SF₆ gas handling applications involving GIS, circuit breakers, and other SF₆-insulated electrical equipment.

Working Principle
The KSLH-30WY/20-63-300MZ combines an SF₆ compressor, vacuum pumping system, storage vessel, filtration and drying system, valves, and measuring instruments into one integrated service cart.
During SF₆ recovery, the compressor draws SF₆ gas from the electrical equipment and compresses it to a high pressure. Based on the pressure-temperature characteristics of SF₆, the compressed gas is liquefied and transferred to the storage vessel or a connected gas cylinder.
During the recovery process, the filtration and drying system helps remove moisture and particulate contaminants from the recovered SF₆ gas.
For vacuuming, the vacuum pumping system evacuates air and residual gas from the electrical equipment before SF₆ charging.
For charging, the system provides two automatic charging modes:
- Balanced Charging using the pressure of the storage vessel
- Compressor-Boosted Charging for applications requiring higher charging pressure
This integrated configuration allows one service cart to perform the major SF₆ gas handling operations required during electrical equipment servicing.
Automatic Operating Modes
The PLC control system provides four main automatic operating modes.
Vacuuming
The vacuum system evacuates the connected electrical equipment to the required vacuum level before SF₆ charging.
SF₆ Recovery
SF₆ gas is recovered from the connected electrical equipment and liquefied for storage.
Balanced Charging
SF₆ is charged into the electrical equipment using the pressure available in the storage vessel.
Compressor-Boosted Charging
The SF₆ compressor provides additional pressure during charging when storage vessel pressure alone is insufficient.
Control System
The PLC touch-screen interface provides a clear display of the system process flow and operating status.
Adjustable operating parameters include:
- Vacuum Stop Value
- Vacuum Stop Delay
- Compressor Protection Setting
- Charging Termination Setting
- Charging Termination Delay
- Recovery Termination Setting
- Recovery Termination Delay
The system also provides a manual operating interface for individual valve and component control when required.
Filtration & SF₆ Gas Drying System
The KSLH-30WY/20-63-300MZ includes a filtration and drying system for conditioning recovered SF₆ gas.
The system uses a self-regenerating desiccant filter. The desiccant can be regenerated through vacuum heating activation, reducing the need for frequent replacement of the drying medium.
The specified moisture content of recovered SF₆ is ≤60 ppm/V under the stated test conditions.
