Diesel generator sets, used for either prime power or Emergency Standby power must be maintained in order to provide reliable power when needed.

If you use your generator for main source of power for your premises or heavy electrical load equipment you will be aware of the need to keep it regularly serviced and any faults that arise need to be dealt with quickly.

You can rely on NJB Generators to provide a regular suitable maintenance routine to ensure that your generator remains in top condition for when you need it most.

With Standby emergency power generators it is still crucial to have them maintained even though they do not run for many hours a year.

Common faults can be failure of engine coolant heaters, battery chargers and resultant flat batteries causing failure to start when required. Regular checks will pick up on any faults of this nature and get them repaired.

This will ensure they are immediately available when called for during a mains failure, thus allowing you to carry on with your daily life at home or continue with your business operations.

Our standard package for standby generators includes two visits per year, comprising one “A” and one “B” level service.

  • Oil Filter Change
