The Smart Power Control (SPC3) system in the Develon DX420LC-7 crawler excavator now consumes 11% less fuel than the previous generation. The system supplies just the right amount of oil and prevents energy wastage. This is partly due to the stage 5 engine that is in it, so that you can take your company one step higher on the CO2 performance ladder.
