The Senville SENTC-48TD is a 4 ton (48,000 BTU) top discharge central heat pump system engineered for larger residential spaces. The outdoor condenser pairs with a ducted indoor air handler to deliver strong, consistent airflow and efficient temperature control through your home's duct system, with the capacity to keep up during peak seasonal demand. A Twin-Rotary DC Inverter compressor matches output to the load, and the Hyper Heat design keeps heating down to -4°F outdoor.
Rated at 17.6 SEER2, 11.3 EER2 and 9.1 HSPF2 (Region 4), the system runs on 208/230V single-phase power and uses R-32 refrigerant. Select the line set length (16 Ft. or 50 Ft.) and an optional auxiliary electric heat kit (5K, 10K, 15K or 20K) to fit the installation.
