• For domestic hot water heaters, process cooling, hydraulic oil cooling etc.
• Suitable for transcritical systems, CO2 cascade systems and heat pumps


As one of the most recent product innovations, Alfa Laval designed the brazed heat exchanger optimised to withstand high pressures without the need of costly frames. Thanks to its specific design it can reach pressures as high as 70 bar at +90°C or 65 at +125°C. It can be used in transcritical systems as evaporator or intermediate heat exchanger, as well as in CO2 cascade systems and heat pumps.
