The Big Size Package Type E Series Water Source Heat Pump is designed for large commercial and industrial HVAC applications requiring high cooling and heating capacity, stable operation, and energy efficiency. The series covers capacities from 21 kW to 98 kW and is available in horizontal and vertical configurations to suit different installation layouts. Each unit is fully run-tested with water in both cooling and heating modes and adopts scroll compressors, a coaxial water-to-refrigerant heat exchanger, and high-efficiency air coils for reliable heat transfer performance. The system uses R410A environmentally friendly refrigerant and supports intelligent control through the MGP50 microprocessor control system with MODBUS communication, allowing centralized monitoring and building management system (BMS) integration. The robust cabinet structure, flexible airflow arrangements, and multiple ESP options make this series suitable for hotels, shopping malls, hospitals, office buildings, industrial plants, and geothermal or water-loop HVAC systems.
