Mitsubishi Electric Trane HVAC US (METUS) has introduced two MSZ/MUZJP Model 115 Volt Heat Pumps. Part of the METUS M-Series product lineup, each 115-volt heat pump system utilizes one breaker spot in an electrical panel versus the typical two breaker spots. A single zone system, the MSZ-JP model indoor unit and corresponding MUZ-JP model outdoor unit are suited for residential and light-commercial applications, such as hotels and restaurants. Available in 9- and 12-kBtu/h capacities, the system is SEER 17.0, HSPF 9.3 to 11.00, and EER 9.9 to 12.0. The outdoor unit heat exchanger has been treated for slow corrosion caused by airborne salt and sulfur in coastal and high sulfur areas.
