• 50% longer service life in high-flow systems

B. Industrial Gas Purification

Gas Type	Critical Role	Risk Mitigated
N2/O2	Prevents molecular sieve poisoning	Maintains 99.999% purity
H2/NG	Eliminates combustion efficiency loss	Avoids hydrogen embrittlement
Cl2/CO2/LPG	Removes corrosive moisture	Reduces pipeline degradation

 

C. Refrigeration & Cryogenic Systems

• Applications:
• Refrigerant dehydration (R22, R134a, etc.)
• Pharmaceutical freeze-drying (-50°C gas supply)
• Benefit: Prevents ice blockages in expansion valves

D. High-Tech Gas Supply

• Semiconductor/Laser Processes:
