DND Condenser

Wire on tube condenser, which used for direct cool refrigerator, water dispenser, water cooler and ice cream maker.
More than 1000types of design, we could producing as drawings, and make design for customers, too. 
Support with better prices ,good quality and valuable services.

Wire and tube condensers are used for larger refrigeration products with higher thermal performance requirements. Features are as follows:

1) Plug-in installation, good air circulation around it, can ensure good heat dissipation efficiency in a limited space.
2) Refrigerant flow and circulation are smooth, which can reduce the load of the compressor, save energy, and extend the service life.
1. Technical parameters:
Raw materials
1. Condenser tube: Coil-welded steel pipe 4.76－6.35 * 0.71mm
2. Cooling wire: low carbon steel wire 1.4-1.6mm
3. Support: Cold-rolled sheet T = 0.6-2.0mm
4. Structural form: welding of steel wire and Bondi pipe
Product performance
1) The product adopts electrophoretic paint to meet the anticorrosive needs of the use process
2) The internal cleanliness can meet the requirements of CFC or R134a refrigeration system
3) Satisfy the heat dissipation performance requirements of the designed refrigerator and freezer.
Second, R134a refrigeration system piping standards:
1) Residual moisture ≤30 mg / ㎡
2) Residual impurities ≤20 mg / ㎡
3) Residual mineral oil ≤7 mg / ㎡
4) Residual chloride ion ≤3 mg / ㎡
5) Residual paraffin ≤3 mg / ㎡
6) Maximum single magazine ≤ 0.5 mm
Third, coating quality performance standards:
