Key process: Preparing materials cleaning roughing surface-printing riveting- rolling annealing - blowing up punching folding and sharpening adding the capillary assemble welding leakage testing cleaning and drying coating -curing- inspection packing.
Roll bond plate tube evaporator is made up by two pieces of printed aluminum plates through the crafts contain reunite, roll and blow bulge.
1) Size can up to width 700mm, length 2000mm, thickness of finished plate1.2-1.8mm
2) Surface treatment: No treatment or Powder coating;
3) Inner quality: No leakage. It can meet the requirements of inner cleanliness of CFC refrigerating medium and non-CFC refrigerating medium.
4) We can produce according to the drawings or samples provided by you, also we can help you design and produce different models of roll bond evaporator.
Now it is popular in Nigeria, Morocco, Pakistan, Egypt and other maintenance markets.
We are very familar with these markets now.
