* By using a distributor for liquid separation, the refrigerant distribution in the tube side is ensured to be uniform, improving the design of the tube side and maximizing the use of heat exchange area, resulting in good heat transfer performance

*In terms of process, the expansion joint has been changed to welding, which has high compressive strength and greatly improves the reliability of the product.  The tube sheet and tube box are eliminated, and the distributor, collector and heat exchange tube are welded together, so that the multiple systems are completely independent and there is no risk of refrigerant leakage;

*Resistant to dirt, blockage, and freezing, with short tail overhang and good vibration resistance, overcoming the problem of vibration and fracture of heat exchange tubes

* Superior heat transfer performance, the inner tube adopts a patented multi head spiral tube structure and surface enhanced heat transfer technology;

* The water flow channel is large, resistant to dirt and blockage, and has good freezing resistance. The turbulent flow of water inside the spiral tube, making the heat exchanger have good anti scaling characteristics

*Certified by UL, suitable for refrigerants such as R134a, R407C, R410A, R32, and CO2

Featured with thin film flow heat exchange, falling film heat exchanger has  20% higher performance than flooded type,and the liquid level fluctuation caused by the change of working conditions has less impact on the performance, and the influence of the liquid level on the evaporation pressure is greatly reduced. 

Adopting a two-layer drip type two-phase distributor, the refrigerant is evenly distributed

The refrigerant charging amount is much less than flooded type, which reduces the unit cost and minimize the negative impact of freon on the environment;

Reduce the compressor liquid strike risk, improve system oil return efficiency, and enhance system reliability.

* Patented structure design, higher heat exchange efficiency, compact unit size and small footprint;

* The water side adopts a closed ring structure distribution and collection tank design to achieve even water distribution；

* The use of small diameter heat exchange tubes or heat exchange plates improves the heat exchange performance on refrigerant side, and greatly reduces the refrigerant charge amount；

Innovative filling material structure and design increase the heat exchange area between humid air and water, and reduce the height of the unit.

Design different plate structures and distribution for different working conditions of customers to ensure optimal performance ;

Advanced automation equipment is used to ensure that manufacturing process is consistent and stable;
