Variable speed drives maximize energy efficiency by constantly adjusting motor speed with air demand to provide optimum performance and reliability → Delivering maximum operating flexibility with efficient full and part load performance, VSD's are ideal for applications with fluctuating air demand.
Align Energy to Air Demand
Adjusting motor speed for optimum performance, drawing power in direct proportion to the load. Energy consumption approximates zero at no-load vs. full-voltage drives consuming between 13% to 85% of their full-load consumption.
Eliminate Current Spikes on Startup
Eliminates in-rush current & amperage surges on start-up by gradually starting motor speed - contributing to overall energy efficiency.
Eliminate Artificial Demand
Pressure tracking controls ensure that energy-use is optimized by producing only as much air as is needed at set pressure, avoiding artificial demand.
Ideal for Fluctuating Air Demand
Delivers maximum operating flexibility with efficient full & part load performance.
The initial fixed cost of a rotary screw air compressor is only a fraction of it’s total lifecycle or operational cost → The greatest proportion of costs incurred in the operation of a compressed air system are it’s energy costs.
VSD’s are a considerable opportunity in reducing cumulative energy costs → Up to 24%.
Upgrading to variable-speed air compressors qualifies for cash-rebates from local utility or government energy-savings programs in many areas. Save a considerable amount off your investment.
