Daikin Australia launches its third generation of Air Cooled R32 Scroll Chillers. The new series features an extended capacity range of up to 1012kW and is available in two efficiency versions with EER up to 3.368 and IPLV up to 5.165 and three sound configurations while extending the operation envelope and occupying a smaller footprint compared to its predecessor for maximum flexibility in operation.

This latest iteration of Daikin’s R32 chillers is available in two variations: a cooling-only model (EWAT) and a hydronic free cooling model (EWFT). Both have been optimised to deliver exceptional performance when operating in partial or full loads with many new features.

The fan used in the latest generation incorporates an in-house design that increases the air flow and delivers a lower noise level while maintaining higher efficiency. A full metallic compressor enclosure with soundproof insulation protects the compressor while reducing sound by 4dB(A) down to 84dB(A) paired with fixed speed EC fan. Additionally, several new options are introduced such as rapid restart, integrated sequencing capability and performance monitoring that were previously only available on screw chillers.

Depending on the capacity design, the chillers consist of up to two circuits, four compressors and eight fans per circuit paired with a highly efficient brazed plate and microchannel heat exchanger. With chilled water temperatures up to 30°C, the latest chiller range is suitable for a wide range of applications from large commercial buildings to industrial facilities and data centres.

Through the application of R32 refrigerant in these chillers, the environmental impact is significantly reduced. Compared to R410A refrigerant, R32 has a 66% lower global warming potential. Furthermore, the Life Cycle Climate Performance (LCCP) of R32 has one the highest efficiency and the best choice compared to other low GWP alternatives such as R454B and R466A. Daikin became the world's first company to succeed in applying R32 to air conditioners in 2012 and air cooled chillers in 2018 by leveraging its expertise as the only manufacturer that develops and manufactures both air conditioners and refrigerants.

Overall, the new range of air cooled scroll chillers represents a significant improvement over the previous generation, offering superior performance and flexibility for various applications.
