1.Production Description:
Condensers and cooling coils decide the effectiveness of a machine to cool an environment and enabling it to work at its best involves a lot of complex sciences, at Prijai we put a great deal of effort to work on every tiny details to maximize its efficiency. Our on-going research and superior engineering makes our cooling coils and condensers the best.

2.Feature:
a. Expanding production process makes the fins and tubes closely contact;
b. Efficent heat exchange is able to meet the European A+,A++standard;
c. It is suitable for refrigerator with flex door,or multi-doors.
Â
3.Usage: it is widely used in various types of  refrigerator, freezer, ice box etc cooling system.
Â
4.Specifications:
Tube : Auminum diameter:φ4.76, Φ8mm  ;  wall thickness:0.6-1.0mm;
Fin:Alumium foil thickness: T=0.12-0.25mm;    Â
Side plate:Al plate T=0.8~1.5mm;
Â
5. Key process:Â
Tube bending--fin punching--Â tube expanding--degreasing--welding and assembly--leakage testing--inspection--packing.
Â
6. Residual requirement:
Pipeline volume (cm3): | ≤100 | 101-200 | 201-400 | 401-800 |
Residual Moisture (mg): | ≤10 | ≤20 | ≤25 | ≤30 |
Residual Impurity: | ≤ 100mg/m2 |  |  |  |
Biggest single impurity: | ≤2mg |  |  |  |
Â
7. Technical Standards:
1)Diagonal-Inserting
2)Pull-Expanding
3)Press-Expanding
8. Technical Standards
We can produce according to the drawing or sample from clients, also can help the clients design and produce different condenser/evaporator used in refrigerator,freezer, washing machine, heat pump etc.
9. Coating STD
1)Anodic-Oxidation is in accordance with Aluminum titration.
2)Electrophoresis dipping-coating thickness is12-30μm.
3) Chemical hydrophilic painting: Natural color.
4)Dipping-coating thickness:12_30μm.
5)Corrosion Resistance( GB2423):salt spray≥200h no corrosion;≥96H no corrosion.
Â
Performance
1)Inner cleanness can match the requirements of R134a& CFC cooling system
2)Capability can match the requirements of refrigerator or freezer
