MAINTENANCE FREE SOLUTION The biggest operating cost of a genset comes from the routine maintenance except for the fuel consumption cost. Generally, the A-class maintenance interval of the diesel engine defined by the diesel engine manufacturer requires each 250 running hours, including the replacement of lubrication oil and filters. The operating expenses are not only limit to maintenance parts, but also labor cost and transportation, especially in the unattended remote areas. Extending the routine maintenance interval is significant to reduce the operating cost. Regardless of a DC genset or...
