Our Bottom Line for Your Bottom Line
Lowest Total Cost of Ownership

Reduced life cycle cost. The operating and maintenance costs of a standard chiller can often range from 10 to 15 times the initial purchase price of the chiller. Magnitude chillers ofren reduce this ratio to four or less, resulting in payback periods as low as 1 to 2 years. | Small unit footprint helps the Magnitude chiller fit in buildings where space is limited. |
Magnetic bearing centrifugal compressor eliminates the efficiency-robbing friction inherent in traditional centrifugal chillers. | Unmatched unloading with the integrated VFDs since the on-board digital controls reduce compressor speed to match the load. |
| Integrated VFD optimizes part load efficiency, a key performance feature since most chillers operate at part load 99% of their life. | 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. |
| Sustainable performance - positive pressure, oil-free design eliminates the performance degradation due to non-condensables and oil contamination of the refrigerant. | Low inrush current at star-up is ideal for operation with backup or emergency power systems. |
| Easy integration with our Open ChoicesTM feature using BACnet®, LonWorks® or Modbus® communications without an expensive gateway panel. | Quality assurance and quicker start-up are enhanced by the factory testing of every unit at job site conditions. |
| R-134a refrigerant has no ozone depletion potential and no phase-out schedule. | Seismic compliance with both IBC seismic certification standards and OSPHD pre-approval. |
| Reduced maintenance costs due to the elimination of the oil, oil system, purge system, and shaft seals found in older technology chillers. | LEED® points can be earned from the Magnitude chiller's performance in two categories: EAc1, up to 19 points possible; and EAc4, 2 points. |
