Low start-up current thanks to power delay control design.
Use U-type heat exchange tube to improve the heat-exchange efficiency of the complete unit;
Special equalizing plate design of shell and tube: the distribution of refrigerant is more even for improving the heat-exchang-ing efficiency of the complete unit.
Main module patent: any unit can be set as main module via wired controller.
Up to 16 units (60/71kW) or 8 units (120/145kW) can be integrated freely to get a max capacity of 1160kW thanks to modular design.
