Refra Air Heat Exchangers

We offer a range of high-performance air heat exchangers designed to suit various commercial and industrial refrigeration needs. Our gas coolers are built for CO₂ systems, using robust tubes rated for pressures up to 120 bar and fitted with EC fans and aluminium or copper fins. For year-round cooling with minimal maintenance, our dry coolers are a practical choice, ideal for data centres and large facilities where reliability and low operating costs matter. We also supply direct-expansion evaporators, designed for low and medium temperature systems, available as standalone units to suit different refrigeration setups.

Air Cooled Condensers

A condenser is designed to transfer heat from a working refrigerant to the surrounding air. The condenser relies on the efficient heat transfer that occurs during phase changes. Refra condensers can be designed in a wide capacity range and various frames, making them suitable for small and large commercial or industrial refrigeration systems. We ensure, that the production of condensers meets the quality control system standards of ISO 9001:2015. Designed using grooved copper tubes, aluminum or copper fins and single-phase or three-phase axial fans.

Gas Coolers

Gas coolers are heat rejection heat exchangers in vapour compression refrigeration systems that use carbon dioxide (CO2) as refrigerant. Such products are often chosen for cooling high pressure gases and are perfect for CO2 systems. Refra gascooler series are designed on the same frame as condensers, but with 7,94 x 0,54 mm tubes suited for high pressures in CO2 transcritical systems – up to 120 bar. Our gas coolers come with EC fans and aluminum or copper fins. Each unit is pressure tested and shipped filled with nitrogen.

Evaporators

As many refrigeration systems incorporate direct-expansion evaporators, Refra released its own direct-expansion evaporator series, which can be sold separately. Direct-expansion evaporator coils are used in low and medium temperatures refrigeration applications to cool and sometimes dehumidify air.
