Combining 400,000 BTU/h high-stage gas heating input with 290,000 BTU/h of cooling capacity, this all-in-one rooftop system helps deliver reliable comfort while simplifying equipment placement and installation.
The integrated gas furnace provides 400,000 BTU/h of high-stage heating input and 324,000 BTU/h of high-stage heating output, with 300,000 BTU/h low-stage heating input and 243,000 BTU/h low-stage heating output. Two-stage gas heating helps match heating output to changing comfort requirements. The heating section uses eight burners and a dual-diameter tubular heat exchanger with Wrinkle Bend Technology. The unit provides 81% thermal efficiency, with a high-stage temperature-rise range of 25–55°F and a low-stage temperature-rise range of 15–45°F.
The cooling system provides 290,000 BTU/h of nominal cooling capacity with a 13 IEER and 9.8 EER efficiency rating. The system uses R-32 refrigerant and two individually circuited single-stage scroll compressors to provide separate refrigeration circuits. Large-face-area outdoor coils constructed with microchannel technology support efficient heat transfer and dependable cooling performance for large commercial spaces.
With a 13 IEER and 9.8 EER efficiency rating, this system is designed to provide dependable commercial cooling performance.
