Aluminum evaporators are manufactured using a continuous cast mill process, followed by hot rolling and cold rolling stages. These heat exchanging plates are manufactured using the Roll Bond process, with a loop of built-in tubes where refrigerant fluid or gas flows.

Typical Applications

Manufacturing of industrial and household refrigerators.

Standard Format

Evaporator plates

Applicable Standards

None

Relevant Characteristics

• High resistance to corrosion.
• High forming capacity.
• High thermal conductivity.

 


Generally, the plant manufactures evaporators according to customer designs (drawings).
