A variable frequency drive (VFD) precisely matches motor speed to actual demand, and excess revolutions are exactly where your electricity bill \"burns\". The dependence on fans and pumps is cubic: reducing speed by 20% reduces consumption by almost <strong>50%<\/strong>.  <\/p>\n<h2>Where does the VSD provide the greatest effect?<\/h2>\n<p><strong>Pumps and fans<\/strong> \u2014 record-breakers: typical savings of 30-50%, especially where flow is currently \"choked\" with a throttle or damper. <strong>Screw compressors<\/strong> \u2014 15-35%, due to the idle running costs of Load\/Unload cycles. <strong>Conveyors and elevators<\/strong> \u2014 linear savings plus gentle handling of belts and chains.
