01/14/2014 | Daikin Magnitude™ Chillers with RapidRestore™ Offers World-Class Reload Speeds for Mission Critical Applications


First-of-its-kind RideThrough™ capability maintains operation during momentary power loss

magnitudeChiller experts at Daikin Applied know that during a power loss, every second counts in mission critical facilities like data centers and hospitals. To quickly restore cooling capacity when the power returns, the global leader in HVAC is introducing new technology advancements that enable chillers to restart and reach full load operation at world-class speeds and even maintain operation during a momentary power loss.

New Daikin Magnitude™ WME chillers with RapidRestore™ make it possible for the chiller to restart 35 seconds after a power failure and reach 80 percent of full-load in 75 seconds, making it among the fastest centrifugal chiller reload times in the world. In the event of momentary power loss, Daikin's RideThrough™ capability will maintain compressor rotation during the power failure. This first-of-its-kind capability permits the chiller to re-synchronize with the spinning magnetic bearing rotor and return to its pre-power loss capacity within as few as five seconds of power being restored, greatly reducing the nuisance and time delay normally associated with a momentary power failure.

"Daikin's RapidRestore capability provides facility managers with reload times that are almost three times faster than oil-based chillers," said Ray Good, director of centrifugal product management at Daikin Applied. "We believe this will provide our customers with both the ability to quickly recover the cooling load in addition to all of the other proven benefits of the Magnitude centrifugal chillers. This makes WME Magnitude chillers ideal for mission critical facilities that are required to provide cooling for their critical applications regardless of the reliability of utility power."

Daikin Magnitude chillers use oil-free technology that increases reliability and reduces maintenance. Because there are no conventional bearings, and therefore no oil management system or associated maintenance costs, the Magnitude chiller delivers a lower cost of ownership compared to conventional centrifugal chillers. Magnitude also uses HFC-134a refrigerant, with no ozone depletion potential or phase-out schedule.

As a result of its higher sustainable operating efficiency and reduced maintenance, the Magnitude chiller is 40 percent more energy efficient than standard equipment, saving more than $2 million over the life of the machine.

The Magnitude chiller line has been tested and International Building Code (IBC) certified for seismic installations. For critical health and public facility buildings in California, Magnitude chillers have also received the more rigorous Office of Statewide Health Planning and Development (OSHPD) Special Seismic Certification Pre-approval for applications up to 1.6 SDS.
