The HRH056U1LP6 is a hermetic, fixed-speed scroll compressor for air conditioning. It compresses refrigerant with an interleaved fixed-and-orbiting scroll pair sealed in a welded shell, runs at a single speed, and cycles to control capacity. It uses the larger Danfoss H-series body but is wired for single-phase power, which is less common at this capacity and useful where three-phase service is unavailable.

This model is built for R410A refrigerant with PVE lubricant and rated at about 4.7 tons (56,880 BTU/hr at 60 Hz). It runs on 208-230 V single-phase, 60 Hz power and is used in higher-capacity residential and light commercial condensing units and heat pumps on single-phase supply. The code decodes as H (air conditioning), R (residential-platform scroll), H (R410A, PVE oil), 056 (capacity class), U (optimized for 45/100°F), 1 (208-230 V single-phase), L (internal protection), P6 (brazed, spade terminals).
