Multiscroll cooling only and heat puMp air cooled chillers The new ACZ multiscroll family is a new complete range of on-off air cooled chillers for outdoor installations.

acZc for cooling only applications and acZh series for heat pump installationsare the right choices for high efficency and noise sensitive projects at affordable price.

ACZ range has been designed with the aim to provide maximum energy efficiency, very low noise emissions, reduced footprint, easy installation, versatile for every kind of applications and able to be integrated in any monitoring system.

eurovent certified series and design fully based on neW european directivesBoth ACZC and ACZH chillers series have been optimized and entirely designed in accordance with EN14511 and EN 14825 normatives.
