  1. MAGNA3 INTELLIGENCE RELIABILITY EFFICIENCY RANGE

  2. Range 1. What is the range of our current Magna? Number of pumps Voltage Flow & Head Temperature Applications • 2. What is the range of MAGNA3? • Number of pumps • Voltage • Flow & Head • Temperature • Applications

  3. Range • 14 Hydraulic models (11 Single, 3 Twin) • Total 37 pumps • 115V up to 1HP • 208-230V all • 14°F to 230°F • Cast Iron and Stainless • Water & water/glycol up to 50% • Heating, DHW, Solar, Cooling & Geothermal

  4. Reliability How long has Grundfos manufactures and sold circulators? How many Alphas/Magnas installed? What is the percentage warranty rate on Magna? Why so reliable? When was the project for Magna3 started? How many hours have the Magna3 been tested?

  5. Intelligent Control #1 -or - #2

  6. Intelligent Control – Constant Curve H(ft) P (W) Q (GPM)

  7. Intelligent Control - Constant Curve H(ft) P (W) Q (GPM)

  8. Intelligent Control - Constant Pressure H(ft) P (W) Q (GPM)

  9. Intelligent Control - Proportional Pressure H(ft) H Set 50 % H Set P (W) Q (GPM)

  10. What is

  11. Intelligent Control - AUTOADAPT H Max H(ft) 50 % H Max 5 Feet P (W) Q (GPM)

  12. Intelligent Control - AUTOADAPT H(ft) Old AUTO ADAPT Set Point New AUTO ADAPT Set Point 5 Feet P (W) Q (GPM)

  13. Intelligent Control – FlowADAPT/FLOWLIMIT Duty point Performance curve Potential saving compared to an unintelligent pump FLOWLIMIT Potential saving compared to proportional pressure mode Additional saving with FLOWLIMIT 0 25 50 75 100 FLOWADAPT benefits from the advantages of AUTOADAPT, along with the availability to set a maximum flow limit with FLOWLIMIT. Once the desired maximum flow is set, a remarkable energy saving can be achieved. The MAGNA3 continuously monitors the flow rate ensuring that it is not exceeded. This will save the cost of a separate balancing valve. Flow Limit

  14. Intelligent Control - CONSTANT TEMPERATURE H(ft) Q (GPM)

  15. Intelligent Control - DIFFERENTIAL TEMPERATURE H(ft) Q (GPM)

  16. Intelligent Monitoring & Sensing Temperature Speed Flow Power Head Energy BTU History

  17. Intelligent Monitoring & Sensing SAVES $$$ by eliminating the need for additional monitoring equipment and data point integration in the system Operating Mode Setpoint Control Mode Alarm/Warning Power and Energy Pressure Head Flow Speed and Frequency Digital Input/Ouput Motor Current Liquid Temperature Operating Hours Total On Time Number of Starts Return Temperature BTU BTU/hr Differential Temperature and more….. • CIM Accessory delivers all of this data from the pump to the BMS System • Bacnet • Lonworks • Modbus • Profibus

  18. Intelligent Interface Show Units in I/P

  19. Intelligent Interface - Startup

  20. Intelligent Interface – Menu Tabs Show Units in I/P

  21. Intelligent Interface – Monitoring • MAGNA3 comes with a monitoring function, which makes it possible to keep track of the heat energy distribution and consumption within a system. This avoids excessive energy bills caused by system imbalances. • The heat energy meter has an accuracy between +/-1% and +/-10% and makes installing a separate energy metering device within your system superfluous. • Temperature input from return pipe

  22. Intelligent Interface – Work Log Show Units in I/P Every duty point and the operational conditions are tracked and stored in the pump. The 3D work log and duty over time curve, provide instant overviews of historical pump performance and operational conditions. The perfect tools for pump optimization, replacement and troubleshooting.

  23. Efficiency Optimized 3D Hydraulic Design Permanent Magnet Rotor – Stronger Magnets Insulation Shell reduces heat loss through pump housing Compact Stator – reduces copper and resistance losses Composite Rotor Can – reduced magnetic losses Intelligent control sizes pump for demand Integrated Grundfos Sensor, Diff. Press & Temperature

  24. EEI What is EEI (Energy Efficiency Indicator)? When was it adopted? What is its future? What does it mean to us (USA)?

  25. Load Profiles 44% 35% Time % 15% 6% 50% 75% 100% 10 20 30 40 50 60 70 80 90 100 25% Flow %

  26. Why VFD’s? Why are VFD’s used? • What percent of the operating time is the demand on a heating system…… • 100%? • 75%? • 50%? • 25%?

  27. Load Profile for EEI Pavg EEI = --------- x C20% Pref 44% 35% Time % 15% 6% 50% 75% 100% 25% Flow %

  28. Pref for EEI Pavg EEI = --------- x C20% Pref

  29. Pavg for EEI Pavg EEI = --------- x C20% Pref 100% Constant Curve HPhydMax Head Prop. Press. Curve 0.5 x HPhydMax T, 44% T, 35% T, 15% T, 6% 25% 50% 75% 100% Flow %

  30. Energy Efficiency Index is a much better measure of energy usage than BEP 75% Energy Reduction before AUTOADAPT EEI 0.27 EEI 0.23 EEI 0.20 EEI 0.17 MAGNA3 65-120
