Microchannel coils have become a mainstay in the HVAC industry for most air-cooled chillers and other air conditioning equipment. Aluminum microchannel heat exchangers (often abbreviated as MCHE or MCHX) offer a line of advantages for both manufacturers and end-users:
- Reduced refrigerant footprint: internal volume of a microchannel condenser is about up to 60% smaller compared to a finned pack coil with copper tubes of the same capacity.
- High corrosion resistance contributes to longer coil service life.
- Lower required fan power draw as air pressure resistance of MCHE coils is low.
- As a cheaper material, aluminum help keep condenser costs down.
- Low weight.
