Overview
Cooper&Hunter's CH-R48LCU-230VO is a 48,000 Btu/h, 230V single-zone outdoor unit, a powerful and efficient option designed to meet the heating and cooling demands of large residential and light commercial spaces. Advanced inverter technology optimizes compressor activity to precisely match the heating or cooling requirements of the environment, significantly boosting energy efficiency while maintaining consistent performance.
The unit uses R454B refrigerant, a greener alternative with a lower Global Warming Potential (GWP) than traditional refrigerants, and is durably constructed to withstand a wide range of weather conditions for years of dependable operation. Its SEER2 rating of up to 19.8 (per manufacturer specs; this unit's paired submittal shows SEER2 19/EER2 9.5) highlights its energy-saving capabilities, with quiet, robust performance suited to residential and commercial applications alike.
