Variable Speed Drive (VSD)
Atlas Copco’s Variable Speed Drive (VSD) technology closely follows the gas demand and continuously adjusts the motor speed, resulting in energy savings. Coupled with inlet pressure control, VSD maximizes flow, and minimizes required horsepower. By working less to do more, VSD consumes less power, while giving greater process control and requiring less maintenance. When the quantity of gas available from the bio process rises, the VSD motor speeds up to ensure a continuous supply of gas to the grid with very low pressure fluctuation.
