1. All-aluminum evaporator
High-strength aluminum alloy tubes and large sets of aluminum alloy fins are precisely expanded and expanded by imported tube expanders, and the heat transfer coefficient is increased by 35%.
Airtightness test: multiple 25kg / cm2 pressure tests, and 24 hours pressure test.
The end plate tube hole of the fixed aluminum tube is stamped and flanged by the die to reduce the wear of the aluminum tube by the tube plate.
The large aluminum alloy fin design is not easy to frost, easy and clean frost.
Fin spacing: 8mm, 10mm, 12mm, 15mm and 10mm combination.
Defrosting method: water frosting can also be combined with hot ammonia and water frosting.
A wind deflector is installed on the back of the air inlet to prevent water splashing during frosting and make the air inlet even.
 
2. Axial fan
Low-energy-saving and energy-saving axial fan, aluminum fan.
It is equipped with a closed-type three-proof motor for cold storage (IP55 grade), loaded with imported bearings, and filled with low-temperature grease.
The air outlet guide ring of the fan is designed with a streamline bell mouth, which is hydraulically stretched and formed by special equipment at one time, reducing wind resistance and vortex, and making the range longer.
An electric heating belt can be added to the diversion ring of the fan outlet.
Optional imported external rotor fan.
 
3. Unit shell
The standard configuration is milky white sprayed steel plate, but also hot-dip galvanized plate or stainless steel.
Imported CNC equipment and molds are used to complete the product's beveling, punching, tube expansion and unit casing forming.
According to the requirements of customers, we can customize the design of different shapes and different structures of air coolers (such as operating noise, range, cooling area, etc.).
A single unit can be made into a 1500m2 evaporation area.
