Refrigerant Charge Reduction
Microchannel coils offer a very high primary to secondary
surface area ratio� This provides very efficient heat
exchange while maintaining a low internal tube volume� As
a result, the microchannel condenser reduces condenser
refrigerant charge by over 70% (NRGD02A014 vs�
BNED02A015)�
Energy Efficient
The microchannel air-cooled condensers are available with
variable speed EC motors, which vary speed based on
system requirements to provide optimal energy and sound
performance� These condensers are also available with
VFD compatible AC motors�
Corrosion Resistance
The mono-metal construction of the microchannel coils
virtually eliminates the risk of galvanic corrosion� A zinc
cladding standard on all coils provides additional corrosion
resistance for harsh environments�
Sound
Microchannel air-cooled condensers feature quiet variable
speed EC fan motors as a standard� Optional VFD
compatible AC fan motors are also available�
Lighter Weight
Over 20% lighter than comparable round-tube, plate fin aircooled condensers�
Lower Height
Approximately 25% lower cabinet height (with same
clearance) than comparable round-tube, plate fin
condensers�
Structural Robustness
The coils used in this unit are extremely rigid and resistant
to damage�
Warranty
Microchannel air-cooled condensers feature a standard
2 year product warranty and a 7 year warranty on the
microchannel coil� The VFD compatible AC motors have a
2 year warranty while the variable speed EC motors come
with a 3 year warranty�
Environmentally Friendly
100% recyclable, all -aluminum coil�
