Magnitude® Chiller, Model WME 400 to 700 tons

Proven Technology, Proven Reliability
Magnitude chillers have proven their reliable, efficient performance in thousands of installations worldwide since their introduction.   

      

The Oregon Museum of Science & Industry in Portland invested in a 550-ton Magnitude magnetic bearing chiller and a Templifier heat recovery chiller as part of an HVAC system upgrade that saved an estimated $90,000 in annual energy costs and earned the museum $345,000 in incentives from their utility.  Read the article on the Energy Trust of Oregon web site. 

 

The “Emerging Technologies” article in the ASHRAE Journal looks at the energy savings and continuing innovations provided by magnetic bearing compressor chiller technology. Read the article> 

          

 

Energy Savings

Energy Savings
The Daikin McQuay Magnitude® chiller is the most energy efficient chiller in its size range with part load performance as low as .311 kW/ton IPLV.

And it's up to 40% more energy efficient than standard centrifugal chillers, saving more than $2 million over the life of the unit.

 

Quiet
The Daikin McQuay Magnitudechiller is the quietest chiller in its size range with sound pressure ratings as low as 76 dBA per AHRI 575. It's ideal for sound sensitive environments such as schools, performance halls, museums, condominiums and libraries.

 

 Ideal for Retrofit and Replacement
The compact size of the Magnitude chiller makes it ideal for retrofit and replacement installations. Some models can even fit through a standard 36-inch door without dissassembling the shells.

Our Bottom Line for Your Bottom Line

Lowest Total Cost of Ownership

Magnetic bearing centrifugal compressor eliminates the efficiency-robbing friction inherent in traditional centrifugal chillers.

Small unit footprint helps the Magnitude chiller fit in buildings where space is limited, making it ideal for retrofit projects.

Integrated VFD optimizes part load efficiency, a key performance feature since most chillers operate at part load 99% of their life.

Unmatched unloading with the integrated VFDs since the on-board digital controls reduce compressor speed to match the load.
Sustainable performance - positive pressure, oil-free design eliminates the performance degradation due to non-condensables and oil contamination of the refrigerant.

Touch screen operator panel is graphically intuitive and easy to use for enhanced operator productivity.  Important status and control information is available at a glance or at a touch.

Reduced maintenance costs due to the elimination of the oil, oil system, purge system, and shaft seals found in older technology chillers.

Low inrush current at star-up is ideal for operation with backup or emergency power systems.

R-134a refrigerant has no ozone depletion potential and no phase-out schedule.

Quality assurance and quicker start-up are enhanced by the factory testing of every unit at job site conditions.

Easy integration with our Open ChoicesTM feature using BACnet®, LonWorks® or Modbus® communications without an expensive gateway panel.

Seismic compliance with both IBC seismic certification standards and OSPHD pre-approval.
LEED® points can be earned from the Magnitude chiller's performance in two categories: EAc1, up to 19 points possible; and EAc4, 2 points.
