A2L R-SERIES NEXT-GEN MINICON
1/2 to 6 HP Air Cooled Condensing Units
The Next-Gen MiniCon R-Series units, ranging from 1/2 to 6 HP, are engineered for increased efficiency, enhanced features, improved serviceability, and a wider selection of cataloged options. These units are well-suited for various commercial applications, including cafeterias, convenience stores, restaurants, and fast food outlets, offering versatility for numerous other applications. Constructed from high-quality materials, they provide increased flexibility and significantly improve efficiency, leading to lower long-term operating costs. The compact product line is designed to utilize refrigerants R454A, R454C, and R455A. Available with scroll compressors, the standard Next-Gen R-Series is rated for operation in ambient air temperatures up to 110° F.
Integral Sub-Cooling Circuit
All Next-Gen MiniCon units feature an integral sub-cooling circuit. This design allows saturated liquid refrigerant to flow from the receiver to the condenser, where it is sub-cooled by ambient air. This process provides an average of 3 to 5° F of sub-cooling, which enhances efficiency and ensures optimal expansion device operation.
The sub-cooling circuit involves the flow of saturated liquid from the receiver to the condenser coil, where it is cooled by ambient air. The resulting subcooled liquid then proceeds to the expansion valve.

Capacity Data (BTUH)
Extensive capacity data tables are provided for various refrigerants (R454A, R454C, R455A) across different ambient and suction temperatures for both Medium/Extended Medium and Low Temperature models. These tables detail performance metrics for a wide range of configurations, including specific model numbers, compressor model numbers, and corresponding BTUH outputs under varying conditions.
Additional Compressor Cooling
Graphs illustrate the conditions under which additional compressor cooling is recommended.
Medium Temperature Models
A graph plots Ambient Temperature against Suction Temperature, showing distinct lines for R454A, R454C, and R455A refrigerants. The text "Additional compressor cooling is recommended for ambients above the lines shown." advises users on optimal operating parameters. This option typically includes dual pressure control, insulated suction line components and piping, liquid injection (TREV), and a suction accumulator.
Low Temperature Models
A similar graph for Low Temperature models displays Ambient Temperature versus Suction Temperature for R454A, R454C, and R455A refrigerants. The recommendation "Additional compressor cooling is recommended for ambients above the lines shown." applies here as well. This option typically includes dual pressure control and insulated suction line components and piping.
