Daikin Applied next-gen 800-ton chiller improves performance in harsher climates

by Brianna Crandall — October 17, 2016 — Daikin Applied’s innovation in chiller products and the embedded technology continues with its newest developments in the high-efficiency Magnitude WME Generation 2 magnetic bearing chiller.

Firmly grounded in Daikin’s oil-free, magnetic bearing compressor technology, the Magnitude WME Generation 2 builds on its proven performance with a redesign of the single compressor WME models from 400 to nearly 800 tons.

Daikin Applied Magnitude chiller

Magnitude WME Generation 2 magnetic bearing chiller builds on proven energy-saving performance with redesign to nearly 800 tons, with lower operating costs and first costs.

The Magnitude WME Generation 2 is engineered to provide improved performance, especially in harsher climates; lower operating costs; and improved first costs, making it an even more attractive choice for more customers and applications.

Exclusive Daikin compressor technology offers a wider operating envelope to meet many demanding applications, giving designers the flexibility and performance to match their project requirements with substantially improved savings over the life of the unit.

The Generation 2 introduction builds on the chiller’s proven energy-saving performance — reportedly up to 40% more efficient than standard centrifugal chillers — and oil-free design for longer machine life and increased reliability.

Enhanced customer benefits include:

  • Higher Lift Capability — For customers who operate in harsher climates and need life and load performance that match their conditions, the WME Gen 2 features two impeller options.
    • WME 501 and 701 — Model designation for WME models optimized for standard lift conditions such as AHRI conditions.
    • WME 502 and 702 — Model designation for WME models optimized for lower load and higher lift conditions. The high lift models can now operate with up to 95°F entering condenser water temperature.
  • Improved Unloading — Where designs call for unloading at constant entering condenser water temperature, Magnitude WME Gen 2 now gives the flexibility to maintain stable chiller operations at low load conditions.
  • Higher Capacity Ratings — WME Gen 2 models can be rated at higher capacities, giving engineers more flexibility to match job requirements without having to move up to a larger capacity machine.
