City Multi VRF outdoor units with R32

Meet tomorrow’s challenges today – with R32. Units that use R32 refrigerant are characterised by their outstanding energy efficiency. In addition, they require smaller pipe cross-sections and thus less refrigerant. These units are available in both the Y-series and the R2-series.

All facts and benefits at a glance:

High performance
Air conditioning systems that use R32 require approx. 20 to 30 % less refrigerant while delivering a higher power output.

Smaller pipe cross-sections
The lower density enables the use of smaller pipe diameters, reducing the amount of material required.

Low GWP value
Boasting a GWP value of 675, R32 refrigerant already meets the requirements of the F-gas Regulation for the year 2021.

Meeting precise demand
Available in sizes 200, 250 and 300 with a cooling capacity of 22.4 kW to 33.5 kW and a heating capacity of 25.0 kW to 37.5 kW.

Application areas
Foyers, lobbies and open-plan offices
