Manufacturing

Coils & Fins - Sheet Metals

Heat treated aluminum alloy ( 8079 ) provide high strength fins. In case of heat pump models, the fins are coated with aluminum, hydrophilic, and corrosion resistance substances. The dies used in the manufacturing process are of the Louver type to increase the efficiency of the coils. Inner grooved tubes from the HVA type to increase heat transfer rate. Usage of evaporative oil to avoid the need for cleaning. Using Flux during the welding process to remove the heating effects from the copper tubes.

1- Treatment Tunnel
a- To wash and phosphatize the metal parts at 50-60¼ C. b- To wash the     metal parts with normal water. c- To complete the phosphatization     process.
2- Water Drying Oven
   to dry the water droplets on the metal parts from the of the treatment    tunnel at 100 ¼C
3- Robotic Electrostatic Powder Painting Machine
    To spray the powder paint automatically.
4- Paint Drying Oven
   To dry the powder paint at  200 C for 10  minutes .
