Heat pump chillers in R32 and R454B versions
ITALY: Swegon is launching a new range of chillers and heat pumps using lower GWP refrigerants R32 and R454B.
The Blue Box Zeta Sky range is ErP 2021 compliant with SEERs of up to 5.2 and SCOPs to 5.01.
In a range of sizes from 30 to 240kW, with inverter versions, the new units include scroll compressors and plate heat exchangers with single or double circuits. Energy saving EC axial fans can be specified and there are multiple low noise options.
Described as one of the most compact unit in the market in the 100-250kW range, the new chillers and heat pumps still allow plenty of room for hydronics circuits, and recovery exchangers.
