The Apex series of 15- to 25-ton packaged cooling and heating units is equipped with independent scroll compressors with individual refrigerant circuits to provide part-load operation. The series includes four-stage units with four compressors and two-stage units with two compressors, both of which have gas and electric utility knockouts on the sides and bottom that eliminate the need for panel cutting. When charged with R-410A refrigerant, the units have an energy efficiency ratio ranging from 10.4 to 12.4 and feature electronic spark ignition and power-vented combustion with steady state efficiencies of 80%.
