Permanent magnet variable speed compressors built around one thing: the electricity bill. Where your air demand swings through the shift, BD’s PM VSD range tracks it instead of blowing off the difference.


Over a typical machine life, electricity dwarfs the purchase price and the maintenance combined. Fixed-speed compressors handle varying demand by unloading, running the motor while producing nothing useful.
BD builds permanent magnet variable speed machines that vary motor speed with actual demand, and the saving shows up on the meter within the first billing cycle on a genuinely variable load. The range covers PM VSD screw across the EPM, LPM and LS series, plus two-stage, scroll, low-pressure and oil-free machines, with onboard monitoring that reports real running data rather than hours on a clock.
