Cost Effective

Independent panels provide quick access for unit setup.  Installation time is reduced by easy power and control wiring access.  The factory installed filter-drier means less time spent brazing and charging the system.  The small base dimension and reduced unit clearances make for easier retrofits.

Quality Condenser Coils

High-efficiency microchannel aluminum coils are manufactured using an improved material system, providing reliable performance and small unit size.

Flex Coils with TXV Matches

A true bolt-on TXV, valve assembly and equalizer tube is available with no brazing required. Different TXVs are available for older copper coils (Aeroquip fitting) and for new MaxAlloy™ aluminum coils (Chatleff fitting).
