1. Introduction
This product is ideal for use in many different applications, such as chillers and commercial split/roof tops. MCHEs have an ingeniously simple all-aluminum design that is not only lightweight but also prevents galvanic corrosion. The refrigerant-carrying tubes are formed to optimize heat transfer, enabling the production of more compact, but equally effective, cooling solutions. The smart louvered fin design maximizes surface  contact, reducing the air-side pressure loss, improving efficiency and reducing noise levels.
2. Benefits
a. MCHE is more suitable for high working pressure of R410A
b. Refrigerant charging can reduce 50% at most
c. Increase 30% heat transfer efficiency than traditional copper tube fin heat exchanger
d. The Air resistance can be reduce 30%
e. The weight of MCHE is light, its volume reduce 50% compared with copper and aluminum fin heat exchanger
f. All aluminum heat exchanger easy to recycle
g. 100% brazing, the smaller performance degradation
h. 100% aluminum, more resistance to electrochemical corrosion
