Features and Benefits The Compressor Technology Cutting-edge magnetic bearing technology enables outstanding energy efficiency and reliable, long-life operation. The Magnitude chiller’s exceptional efficiency is due to the direct drive magnetic bearing compressor technology. This design eliminates the friction inherent in traditional centrifugal compressors that can reduce efficiency. A digitally-controlled magnetic bearing system replaces conventional lubricated bearings.
Features and Benefits Open Choices™ BAS Flexibility Integrated Variable Frequency Drives The exclusive Open Choices feature provides seamless integration and comprehensive monitoring, control, and twoway data exchange using industry standard protocols LonTalk®, BACnet™ or Modbus™. Open Choices offers simple and inexpensive flexibility to use the Building Automation System of your choice without an expensive gateway panel.
Features and Benefits and at 90°F (32°C) ambient temperature). When service is required, the refrigerant charge can be pumped down into the condenser by compressor operation and use of a refrigerant transfer unit. Elimination of the cost and space requirements of an external storage tank is a significant Daikin advantage. Unit Control Features The Magnitude chiller control system consists of three major components: the unit control panel and the operator interface panel and the VFD power panel.
Features and Benefits will affect the quantity of refrigerant in the chiller. Most WME configurations will qualify for EA Credit 4. Contact your local Daikin sales representative for more information. IBC/OSHPD Seismic Certification Daikin Magnitude Chillers have been tested and certified by an independent agency, experts in seismic analysis and design to meet IBC seismic and OSHPD pre-approval.

Application Considerations Application Considerations Location Requirements Condenser Water Temperature Rise Daikin Magnitude units are designed only for indoor, weatherprotected, non-freezing area consistent with the NEMA 1 rating on the chiller, controls, and electrical panels. Equipment room temperature for operating and standby conditions is 40°F to 104°F (4.4°C to 40°C). The industry standard of 3 gpm/ton or about a 9.5°F (5.3°C) delta-T works well for most applications.
Application Considerations Condenser Water Temperature When the ambient wet bulb temperature is lower than design, the entering condenser water temperature of Magnitude WME chillers can be lowered to improve chiller performance. Chillers can start with entering condenser water temperatures as low as 40°F (4.4°C). For short periods of time during startup, the entering condenser water temperature can even be lower than the leaving chilled water temperature.
Application Considerations Include thermometers and pressure gauges at the chiller inlet and outlet connections and install air vents at the high points of piping. Where noise and vibration are critical and the unit is mounted on spring isolators, flexible piping and conduit connections are necessary. Variable Fluid Flow Rates and Tube Velocities Many chiller system control and energy optimization strategies require significant changes in evaporator water flow rates.
