Pumps & Fans Control (Buildings)

Pains & drivers

• 70% of electrical consumption in Industry is used to turn motors. 33% of them control Pump or Fan Applications
• Most of Pump and Fan applications are driven by a DOL solution of SoftStarter. This means that the motor runs at full speed and the flow variation is obtained. The energy consumption falls very little when the flow decreases. At 80% of the nominal flow, the energy consumption remains at 95%. The potential for savings on the installed base is huge
• CEMEP association has made a simulation for the European market. The use of Drive in such applications could save 900 M Euro/year and 4 Million tonnes of CO2/year

How can a customer manage energy more efficiently?

• To save energy we have to:
  - drive the motor with a frequency inverter instead of a contactor or Soft Start
  - remove the restriction device (valve or damper)
• The AC Inverter allows to adjust the speed of the Pump or the Fan, therefore the Flow
• The result is huge saving compared to conventional solutions:
  - up to 50% for Fan, Pay back of the drive within one Year
  - up to 30 % for a Pump , Payback within 2 years
