Heat exchangers- electrically heated - Import export

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.

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.

Our company’s employees use equipment specifically designed for this purpose – the extractor – to carry out complex dismantling and installation operations of heat exchanger bundles on a daily basis with a sufficient level of quality and safety. It is important to note that the professionals at KERTEX Energija are certified by the extractor manufacturer Peinemann Equipment B. V.
