• For work in air conditioning, refrigeration, and heat pump applications
• Also available as a High Pressure Unit (ACH500)


AC500 is the innovative Alfa Laval brazed heat exchanger that’s specifically developed to work in air conditioning, refrigeration, and heat pump applications. AC500 is a single and double refrigerant circuit unit developed for chillers in the 200-600 kW range; it is suitable to work as an evaporator and a condenser. As ACH500 it can be used in CO2 cascade systems.

Possible applications

- Evaporator in chiller and heat pumps
- Condenser in chiller and heat pumps
