Air dryer with heat recovery system

Compressed air dryers ASD - energy-saving, patented and future-oriented

Advantages:

• Innovative, energy-saving air dryers with patented 3-stage heat recovery system
• Particularly suitable for irregular loads
• Cost-efficient operation
• With Glycol coolant for an optimumal dew point control
• No unnecessary pressure loss due to built-in condensate drain
• Simple, user-friendly control panel
• Optimal performance through automatic control cooling fan that replaces classic pressure switch and thermostat. Less wear parts

Operation and benefits of the glycol cycle

• The water-glycol mixture is cooled when not all cooling energy is required to cool the compressed air.
• When the refrigeration compressor is switched off during partial load, the compressed air is cooled by the cold stored in the glycol mass.
• Only when the mass is no longer sufficiently cool will the refrigeration compressor be switched on again.
• That is why the ASD dryers show their savings potential, especially during partial loads and irregular compressed air requirements.
• When the air compressor starts again after a pause and emits compressed air to the piping system, the ASD dryers immediately cool the compressed air to dew point because the glycol mass immediately supplies the required temperature. Many other systems, in which the cooling compressor can only cool down to operating temperature after a start-up period, allow humid air to flow to the supply network during this time, with all the negative consequences this entails.
