Automated Fuel Cleaning and Monitoring Systems The UltraPure automatic fuel maintenance system continuously monitors the fuel supply using a state of the art PLC micro processor with a user friendly touch screen operator interface. Event log, error review, system communication and flexible system set up are all included in our standard software package. A long life memory back-up battery is standard to afford system integrity even during power loss. Automatic sensing prevents operation during Generator run time. Industry research has shown... It is expected that 4-8% of all diesel engine generators will fail each year due to CONTAMINATED FUEL. During the plant lifetime, 50% of all diesel engine generators experience a failure. Even in the Nuclear Power Industry, a 2% standby engine generator failure is considered acceptable. Standby engine generator systems don't always exhibit these failures, because they are not run very often.
