Working Principle
The LQHV-625 performs gas recovery through a four-stage process:
Extraction: Withdraws SF6 gas from equipment via compressor
Liquefaction: Cools gas to liquid state for storage
Purification: Multi-stage filtration removes:
Moisture (dew point ≤ -60°C)
Decomposition byproducts (SO2, HF)
Particulate contaminants
Recharging: Returns purified gas to equipment
Industry Compliance
Meets critical standards for SF6 gas handling:
DL/T 506-2018 (SF6 Gas Recycling Device Technical Specifications)
IEC 60480 (Guidelines for SF6 reuse)
GB/T 8905 (SF6 Gas Handling Regulations)
Why Choose LQHV-625?
