Anti-corrosion - Import export

Refra heat exchangers for condensers are made of copper tubes and convert the system’s refrigerant gas to liquid form. Usually they are used for refrigeration equipment as a remote condenser or as a part of a condensing unit. Refra condenser coils are made using inner grooved or smooth copper tubes, which range from 5 mm to 12,7 mm in diameter. The frame can be made using aluminum, galvanized or stainless steel and can be coated with a special Aqua-Aero anti corrosion protection. Heat exchangers can be manufactured from low to high capacities to fully meet customer needs.

Refra heat exchangers for gas coolers are made of special K65 copper tubes for high pressures which go up to 120 bar. Such coils are perfect for CO2 systems as they are capable of maintaining the pressure these systems need. Standard units are designed using corrugated fin shape and can be made with aluminum, galvanized or stainless steel frame with Aqua-Aero anti corrosion protection. These products are usually selected and manufactured exclusively according to the customer’s wishes.

Refra heat exchangers for liquid can be designed and manufactured to fully meet customer needs. Super flexible options allow Refra engineers to select the optimal circuit arrangement for required capacities, providing the best possible unit performance. The coils can be designed using various diameter smooth copper tubes which extends the power selection options. Assembled with aluminum or copper fins and aluminum, galvanized or stainless steel frame with Aqua-Aero anti corrosion protection. Coils are suited for small to high capacity commercial or industrial refrigeration systems.

Refra heat exchangers for evaporators are made of aluminum or copper fins and convert the system’s refrigerant liquid to gas. Usually they are used to cool and sometimes dehumidify air. Refra evaporator coils are made using inner grooved or smooth copper tubes, which range from 7 mm to 12,7 mm in diameter. The operating tube pressure reaches 80 or even 120 bar, making evaporator coils perfectly suitable for CO2 systems. The frame can be made using aluminum, galvanized or stainless steel and can be coated with a special Aqua-Aero anti corrosion protection. Heat exchangers can be manufactured up to 50 kW capacity for both low and medium temperatures.
