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 Magnitude® chiller 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.

Reliable
From 2003 through 2011, more than 1,000 Magnitude® chillers have been installed around the world, providing consistent comfort and energy savings. 
Nearly 1000 Magnitude chillers have been installed around the worldNearly 1000 Magnitude chillers have been installed around the world

Ideal for Green Buildings
Ultra-efficient Daikin McQuay Magnitude Chillers are ideal for high performance HVAC systems in sustainable buildings designed to meet LEED® Green Building certification requirements. For information on designing high performance HVAC systems, visit our GreenWay™ System Solutions page.. 

 

Our Bottom Line for Your Bottom Line

Lowest Total Cost of Ownership

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

Small unit footprint helps the Magnitude chiller fit in buildings where space is limited.
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.

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

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