Airedale has pushed the boundaries in the application of scroll compressors to chiller technology and responded to market demand for a compact, efficient high capacity scroll chiller, with the new 460 – 930kW air cooled DeltaChill and 450 – 1010kW DeltaChill FreeCool.
The R410A configured chillers offer exceptional application flexibility, enhanced by combined 182 models; two sound variants and three efficiency levels. Customers, for example, for whom efficiency is paramount, can opt for the highest efficiency level, whilst in applications where space is limited; a more compact chiller can be selected with a standard efficiency level.
To accommodate the increased capacity and achieve as high an efficiency level as possible, whilst maintaining a compact footprint, Airedale has applied compact micro-channel coils in each range, reducing weight and space claim and contributing significantly to a 25% more cooling per square metre. The micro-channel coils reduce airside pressure drop and refrigerant charge and improve maintenance access.
In the high capacity DeltaChill FreeCool, where the micro-channel coil is matched with the free-cooling coil, the larger heat exchanger in the highest efficiency models allows up to 75% of nominal capacity in free-cooling.
