Combining 225,000 BTU/h high-stage gas heating input with 97,000 BTU/h of cooling capacity, this all-in-one rooftop system helps deliver dependable comfort while simplifying installation and preserving valuable indoor space.
The integrated gas furnace provides 225,000 BTU/h of high-stage heating input and 182,250 BTU/h of high-stage heating output, with 168,800 BTU/h low-stage input and 136,700 BTU/h low-stage output. Two-stage heating operation helps match heating output to changing comfort requirements. The heating section uses seven burners and a tubular heat exchanger with Wrinkle Bend Technology. The unit provides 81% thermal efficiency, with a 30–60°F temperature-rise range for both high- and low-stage heating.
The cooling system provides 97,000 BTU/h of nominal cooling capacity with a 14.8 IEER and 11.2 EER efficiency rating. The system uses R-32 refrigerant and two single-stage scroll compressors that are individually circuited. Copper tube/aluminum fin evaporator coils and microchannel condensers support efficient heat transfer for dependable commercial cooling operation.
With a 14.8 IEER and 11.2 EER efficiency rating, the DSG1023DH00001S is designed to provide efficient commercial cooling performance. The direct-drive indoor fan provides a nominal 3,230 CFM airflow capacity, with an operating range of 300–1,600 RPM and a 2.4 HP indoor motor. Two individually circuited scroll compressors provide staged cooling operation for dependable performance.
The packaged rooftop configuration combines the gas furnace, compressors, coils, indoor fan, and controls into a single outdoor unit, helping simplify equipment placement and preserve valuable indoor space. Daikin packaged rooftop units are designed for new construction and retrofit applications and are built to be direct replacements for most rooftop units without the need for a curb adapter. Convertible airflow orientation allows the unit to serve downflow or horizontal applications. The DSG1023DH00001S uses a 208/230-volt, three-phase, 60 Hz electrical supply and measures 93 3/4 inches wide by 60 3/8 inches deep by 54 5/8 inches high, with an overall height of 82.6 inches. The unit has an operating weight of 1,118 pounds and a shipping weight of 1,190 pounds.
The DSG1023DH00001S uses a 24-volt electromechanical controls package and two individually circuited scroll compressors to provide staged cooling operation. The direct-drive indoor fan operates across a 300–1,600 RPM range and provides a nominal 3,230 CFM of airflow. Convertible airflow orientation provides flexibility for downflow or horizontal applications.
The Daikin DSG1023DH00001S is designed for larger light commercial rooftop applications where dependable gas heating and electric cooling are required from a single packaged system. Its 8.5-ton capacity, high-capacity two-stage gas heating section, staged cooling system, direct-drive supply fan, and convertible airflow configuration make it well suited for applications such as retail spaces, offices, restaurants, schools, warehouses, and other commercial buildings.
The DSG1023DH00001S is designed with service accessibility in mind, including tool-less filter access and an accessible internal control box. The refrigeration system uses screw-on style pressure switches for ease of replacement, while the two individually circuited compressors provide separate refrigeration circuits. Factory wiring and testing help support commissioning and start-up, and the direct-drive supply fan eliminates belt and pulley maintenance associated with belt-driven blower systems.
The Daikin DSG1023DH00001S includes a 20-year heat exchanger limited warranty and a 5-year parts limited warranty. Complete warranty terms and conditions are subject to the applicable Daikin warranty documentation.
