Benefits of Energy Saving VSD Screw Compressor with Permanent Magnet Motor

Generalize：Energy can represent over 70% of a compressor’s lifecycle costs. Generating compressed air can account for more than 40% of a plant’s total electricity bill. Most production environments have a fluctuating air demand depending on the time of day, week, or even months per year. With Adekom’s VSD technology monitoring compressed air requirements, fluctuating demand no longer equals high energy costs. Assuming 70% workload running for 5800 hours per year, paid back period for Adekom VSD compressor itself could be 2 – 3 years!

Benefits of Energy Saving VSD Screw Compressor with Permanent Magnet Motor Principle

VSD compressor monitors the system air demand and forming a closed control circuit with frequency inverter, pressure transducer and inverter duty motor. The target working pressure could be set in PLC controller and the system pressure being sourced by pressure transducer, the signal is then converted to 4-20 mA current signal and revert back to the controller. This signal is compared with the pre-set value by PID calculation instantaneously which provides accurate data for the frequency inverter to output corresponding frequency to change the motor speed and in return to deliver the adequate air capacity to match preciously with the system air demand and at last achieving the aims of constant pressure air delivery and energy saving.
