AC70 Brazed plate heat exchanger

Description

AC70 is the innovative Alfa Laval brazed heat exchanger specifically developed to work in air conditioning, refrigeration, and heat pump applications. AC70 is a single refrigerant circuit unit developed for chillers in the 10-80 kW range and heat pumps in the 5-40 kW range; it is suitable to work as an evaporator, condenser, and economizer. As ACH70 it can be used in CO₂ cascade systems.

Possible applications

- Evaporator or condenser in chiller and heat pumps
- Economizer in chiller and heat pumps
