Product Features

◆ Efficient and energy-saving

The compressor adopts the third generation technology of the German brand semi enclosed screw compressor, which, in addition to its well-known good quality, greatly improves energy efficiency at full load and partial load. The unit adopts axial flow fan blades made of special plastic materials. Compared to metal fan blades, not only is the noise lower, but the motor power is significantly reduced, making the overall power consumption lower than similar products using metal fan blades;

◆ Excellent performance

The air side finned heat exchanger is made of hydrophilic aluminum foil and high-efficiency internally threaded steel pipe expansion joint, and adopts an inverted M-shaped structure layout, which makes the air flow distribution more uniform, fully utilizes the heat exchange area, and achieves greater heat exchange efficiency. By combining the system components with independent patented technology and a more reasonable management structure after optimization design, the resistance loss of refrigerant management will be reduced to a very low level, and the performance of the compressor can be fully utilized, resulting in outstanding performance of the unit;

◆ Compact volume

By adopting a large-diameter axial flow fan and an inverted M-shaped structure design, the unit has a more compact volume, a smaller footprint, and is convenient for users to install flexibly;

◆ Reliable control

The unit adopts a PLC programmable controller and SIEMENS (Siemens) color touch screen, which is the most reliable industrial level control product to ensure long-term stable operation of the unit. It also has complete communication functions, making it easy to connect with the building control system. Through the touch screen, not only can one click automatic start/stop be achieved, but also the temperature parameters, solenoid valve opening status, fault status, cumulative operating time, etc. of the unit can be seen, making the operation status of the unit clear at a glance;

Modular combination

Through modular control combination design, it makes customer use more convenient and simple. For multi module heat pump units, the main and auxiliary machines can be controlled. Through a touch screen, multiple units can be controlled to start, stop, load and unload, and the operating parameters of the units can be displayed, making it convenient to use;
