QTHS-1-30
30m³/h SF6 Gas Recovery Service Cart
The SF6 Gas Recovery Service Cart is designed for professional handling of sulfur hexafluoride (SF6) gas in gas-insulated electrical equipment. The unit integrates vacuum evacuation, gas recovery, impurity filtration, storage, and refilling functions into one compact and mobile system.
The equipment enables safe and efficient maintenance of GIS, circuit breakers, and other SF6-insulated apparatus by removing moisture and particulate contaminants from recovered gas while ensuring reliable gas transfer and storage. The system is developed for emission-controlled operation, helping utilities and service teams manage SF6 gas in accordance with modern environmental and operational requirements.
With an integrated compressor system and user-friendly control interface, the equipment is suitable for both substation on-site service and workshop maintenance applications.
The following technical specifications apply to the model equipped with a 30 m³/h compressor, designed for medium-capacity SF6 gas handling applications. This configuration provides a balanced combination of recovery efficiency, equipment mobility, and operational reliability, making it suitable for routine maintenance and service operations of SF6-insulated electrical equipment.
The specifications below outline the main performance parameters, operating conditions, and functional capabilities of the system.
Our SF6 gas recovery, filtration and refilling equipment range is categorized primarily by compressor displacement (2,10, 15, 20, 30 m³/h and above) and vacuum pumping speed, allowing users to select the most suitable configuration according to gas handling capacity and recovery time requirements.
