1, The modular water source/geothermal unit supports applications in all conditions and can switch between multiple modes to fully meet user needs for cooling, heating, and hot water. With an innovative water system, the energy-saving unit delivers an EER as high as 5.7, provides higher energy efficiency when working at a partial workload, and saves energy by 50% compared with other systems after operation in a year.

2, The unit is designed with a comprehensive water system and consists of efficient components carefully selected and designed for a low operation noise. The unit supports fuzzy volume regulation for a narrow range of temperature changes and quickly reaches the set temperature.                        In addition, the unit provides hot water at a set temperature as high as 55°C quickly and steadily to meet requirements for comfortable hot water in all places..

3 With modular design, the unit starts step by step, reducing the shock on the grid, and maintenance of a single unit does not affect running of other units. In addition, the unit provides multiple built-in security protection functions, and supports intelligent and centralized control, facilitating daily management.

4, The leading-edge shell design allows the unit to be installed in an outdoor space such as terrace and rooftop without the need of a dedicated room. The unit delivers a long lifecycle and runs for long. Units may be installed in batches according to project progress. One water system that works in multiple modes saves investment on other devices such as heating and hot water supply devices, thereby saving the energy..

5, The 32RT and 43RT basic modules support free combination of master units and slave units
