The new dedicated open unit design delivers higher capacity and higher pressure effectively and efficiently. Fuel consumption is optimized with the exclusive FuelXpert system. Conventional systems are based on pneumatically controlled engine speed and air inlet without accounting for fuel economy. These systems have focused on the stabilization of the regulating system, but have not looked at the optimal fuel consumption at each load. FuelXpert, via the engine electronic control module, regulates speed and air inlet with a view to optimizing fuel consumption for each working condition. Important when the air demand is lower than the capacity required, the system ensures the right capacity for the application.
