Condenser Section
Microchannel condenser coils are utilized on 3-12.5 Ton non-CDR units except for Heat Pump and 6.5, 8.5, and 12.5 ton
Reheat units. Heat pump and reheat units do not utilize microchannel condenser coils due to the increase on
condensation and drainage.
Microchannel coils offer many advantages over the traditional copper tube/aluminum fin design:
-
Enhanced heat transfer for higher efficiency
-
Low air pressure drop
-
One piece, all aluminum construction minimizes galvanic corrosion (no copper to aluminum contact points)
-
Zinc coating provides further protection
-
Optional epoxy coating is available for harsh environments
-
Maintenance benefits – microchannel coils are more durable than traditional tube/fin design and can handle
higher water pressures during cleaning. Coils are not nearly as deep as traditional tube/fin design (roughly one
inch deep), so debris clears easily during cleaning - restoring performance lost to dust, dirt, and pollen
accumulation.
-
Lower refrigerant charge - microchannel coils require much less refrigerant.
