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.
