The Hot Gas Bypass Valve is a key component in refrigerated air dryers. It regulates hot refrigerant gas flow back into the evaporator during low load conditions, ensuring system stability and protecting the compressor.
Overview The Hot Gas Bypass Valve is a key component in refrigerated air dryers. It regulates hot refrigerant gas flow back into the evaporator during low load conditions, ensuring system stability and protecting the compressor.
Working Principle When compressed air load drops, evaporator pressure may fall too low, risking freezing. The bypass valve opens to redirect hot gas from the compressor discharge to the evaporator, maintaining pressure and preventing ice buildup.
Benefits
Prevents evaporator freezing
Protects the compressor from cold gas return
Stabilizes dew point under varying loads
Reduces maintenance and downtime
Common Issues Without Hot Gas Bypass
Ice blockage in the evaporator
Fluctuating dew point
Compressor damage due to liquid return
Increased maintenance costs
Applications Ideal for systems with fluctuating air demand: CNC workshops, food factories, automation lines.
