Steel wire condensers are used in cooling systems in two types: dynamic condensers and flat condensers. In a wire-on-tube condenser, the wire serves as a fin that enhances heat dissipation. It’s welded onto the tube, increasing the surface area for heat exchange between the refrigerant inside the tube and the ambient air.

Dynamic Condensers

Many refrigerators have dynamic condensers. Air is “forced” across the condenser coils by a condenser fan to aid in removal of the heat being pulled from the refrigerator. Forced air condensers are located under the refrigerator with a fan sitting to the side pulling cool air in from the right front of the refrigerator and exhausting the warm air out to the left front. This warm air could also be passed over the drip pan to aid in evaporating the water accumulated from defrosting. As a general rule, automatic defrost models will have a forced air condenser.

The range and features of the dynamic condensers can be described as follows:
• Serpentines are formed in full automatic machines, commonly out of 4.76±0.08 x 0.70±0.10 mm OD and 6±0.08 x 0.70±0.10 mmOD electric welded steel tubes in coil form.
• Low carbon steel wires are welded in special machines out of 1.3-1.6 mm diameter.
• Inlet and outlet adaptors (stubs) are connected by the Ag/brass alloy brazing method or remain as steel (w/o stubs)
• KONVEYOR engineering team can optimize the design for airflow and space constraints of customer.
• Depending on the customer requirements, the condensers can be assembled with driers, copper heating tubes and then shipped as ready-to-use in the assembly lines.
• All condensers are tested against leak by helium chambers and they meet the related internal cleanliness standards.
• The tested units are zinc plated to 10-12 microns in the fully automatic zinc plating lines.
• As the last operation, the Zinc plated units are coated in a protective, black color lacquer coating (10-12 microns).
For long distance deliveries, condensers are packed in carton boxes, and the boxes are placed firm on Euro-pallets.

Flat Condensers

The static wire on a tube condenser is a wire that is welded onto the surface of the condenser tube. This wire increases the surface area of the condenser, which allows for more efficient heat transfer between the refrigerant and the surrounding air. They are a cost-effective and reliable way to cool the refrigerant.

The range and features of the flat condensers can be described as follows:

• Serpentine form with steel tube OD 4,76 mm and wall thickness 0,7 mm
• Low carbon steel wires are welded in special machines out of 1.3-1.6 mm diameter.
• Covering the condenser with the black powder paint at the range of thickness 50 – 80 microns.
