Two-Stage Gas Heating for Reliable Comfort

The integrated gas furnace provides 240,000 BTU/h of high-stage heating input and 194,400 BTU/h of high-stage heating output, with 180,000 BTU/h low-stage input and 145,800 BTU/h low-stage output. Two-stage gas heating helps match heating output to changing comfort requirements. The heating section uses seven burners and a tubular heat exchanger and provides 81% thermal efficiency. The high- and low-stage temperature-rise range is 30–60°F.

140,000 BTU/h Cooling Performance

The cooling system provides 140,000 BTU/h of nominal cooling capacity with a 14.2 IEER and 11.0 EER efficiency rating. The system uses R-32 refrigerant and two individually circuited scroll compressors to provide staged cooling operation. Large-face-area outdoor coils use microchannel heat exchanger technology to support efficient heat transfer and dependable cooling performance.

Efficient Performance with Direct-Drive Operation

With a 14.2 IEER and 11.0 EER efficiency rating, the DSG1503DH00001S is designed to provide efficient commercial cooling performance. The direct-drive indoor fan has a nominal airflow capacity of 4,200 CFM and uses a 15 x 15-inch fan wheel. The two scroll compressors provide separate refrigeration circuits, while the direct-drive configuration eliminates belt-driven fan components.

Packaged Rooftop Design for Flexible Installation

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. The DSG1503DH00001S 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. The unit has a sound level of 86.8 dB(A) and a shipping weight of 1,316 pounds.

Controls & Comfort

The DSG1503DH00001S uses a factory-installed controls package with a large, well-organized, weatherproof internal control box designed for easy access. Two-stage gas heating provides high- and low-stage operation, while the two individually circuited scroll compressors support staged cooling. The direct-drive indoor fan provides controlled airflow for commercial comfort applications.

Commercial Applications

The Daikin DSG1503DH00001S is designed for larger commercial rooftop applications where dependable gas heating and electric cooling are required from a single packaged system. Its 12.5-ton capacity, high-capacity two-stage gas heating section, dual scroll compressors, direct-drive indoor fan, and packaged rooftop configuration make it well suited for applications such as retail spaces, offices, restaurants, schools, warehouses, and other commercial buildings.

Service & Maintenance

The DSG1503DH00001S is designed with service accessibility in mind, including a draw-through filter section and a large, easy-to-use weatherproof internal control box. High- and low-pressure switches provide refrigeration-system protection, while the two individually circuited cooling systems provide separate refrigeration circuits for service flexibility. Factory wiring and testing help support commissioning and start-up, and the direct-drive indoor fan eliminates belt and pulley maintenance associated with belt-driven blower systems.

Warranty

The Daikin DSG1503DH00001S 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.
