Air-cooled condensers are used in many refrigeration applications, including (but not limited to) food processing plants, supermarkets and restaurants. Brazed aluminium heat exchangers present several major advantages for these applications: They improve energy efficiency, lowering power consumption and reducing the environmental impact of the refrigeration system. The inherent smaller internal volume leads to lower refrigerant charge, which reduces the periodicity of leak inspections and helps them comply with environmental regulations. They lower weight for transportation and mounting, and allow easy maintenance and cleaning that contributes to a reduction of the overall cost.
Brazed aluminium heat exchangers are compatible with most common refrigerants such as R404A, R407C, R134A, R410A and natural refrigerants, and are able to cope with high operating pressures. The choice of materials and combination of alloys in the system are very important, in order to provide corrosion protection and reliable operation. High-strength alloys are specially suited to these applications.
