RF-300 Series Sulfur Hexafluoride SF6 Recovery Device
Applications:
Applies to SF6 gas recovery, purification treatment, storage and recharge for switch of high-voltage switch manufactory, electrical appliance research institute, power plant, power supply bureau, transformers and distribution station.
Main functions:
- The quality of treated gas conforms to the new gas standard stipulated in national standard GB/T 12022-2006.
- Integrated liquefaction, purification and storage of recovered SF6 gas.
- The unique purification technique (invention patent) for cycle purification treatment to recovered gas.
- Unique patented drying filtering technique to remove moisture, decomposed product and impurity in gas
- Oilless compressor imported from American is adopted for recovery with high efficiency
- Dual compressor supercharging technique for improving recovery rate
- The recovery and recharge adopt two-way independent system and compression equipment, so as to avoid cross contamination of gas.
- Independent gas heating system, higher recharge efficiency
- Automatic neutralization treatment of waste gas and impurity, so as to realize pollution-free discharge, and reduce influence of SF6 gas on environment
- The system is equipped with electronic weighing device, for real-time measurement to recovery and recharge of SF6 gas
- Imported PLC control technique
- Embedded industrial control computer, one-key touch screen operation, highly automatic
- Site configuration is available, automatic display of process, instant function operation prompting
- It is equipped with special-purpose temperature, pressure and weight measurement sensor, for real-time monitor to working status of system
- Optional vacuum pumping speed: 200m3/h, 253m3/h (Roots multicell pump)
- It can be vehicular
