Extended Service Interval (ESI) for Your Generator Set
1,000-hour Extended Service Interval (ESI)
The generator ESI option increases the maintenance-free service running interval from 500 to 1,000 hours, ensuring reduced maintenance costs over the life of the generator set, further enhancing the product range for telecom applications and remote installations. With minimum downtime, our innovative approach can also reduce engineer site visits and lower cost as there is less need for extra parts. Contact your Cat dealer today for more information.
The 1,000-hour free generator set maintenance service is enabled using a level valve; oil top up tank; double fuel filter and header, resulting in lower operating costs via:
Reduced labor and support
Reduced Travel Frequency
Less generator set downtime
Reduction in replacement parts required
