Maintain the reliability of emergency power systems with regular maintenance. Did you know that the maintenance of emergency power generators is based on maintaining around-the-clock starting and operational readiness, not on the number of operating hours? Unfortunately, emergency power generator maintenance and testing are often overlooked, which can result in the generator not working when needed. Therefore, emergency power generators should be maintained at least once a year, with monthly test runs.

The failure of a diesel engine used as an emergency power generator differs significantly from those used in vehicles or ships. In the latter, failures often result from the wear and tear of components, while emergency power generators typically fail due to corrosion, moisture, or lack of use.

Emergency power systems consist of a diesel engine, generator, auxiliary systems, automation, and other control systems. The maintenance of emergency power systems requires comprehensive expertise in all these areas, so it is advisable to entrust the maintenance to a professional who is proficient in all aspects of the system. The reliability of the system relies on the quality of equipment components, software, regular testing, and planned maintenance.

At Machinery, we provide maintenance for all diesel generators, regardless of the brand. During maintenance, we use high-quality spare parts and supplies. Our maintenance includes the use of Fleetguard filters and Valvoline Premium Blue engine oil. We use high-quality and long-lasting Fleetguard coolant. For more information, please contact us, and we are happy to assist you in selecting a suitable emergency power maintenance service package!

Regular maintenance and test runs can extend the lifespan of diesel generators. In addition to maintenance, it is essential to consider the emergency power automation system. An outdated automation system is no longer as reliable. The availability of components also diminishes over time, posing a risk to system maintenance.



We provide repair, major overhaul, and testing services for Allison transmissions, without forgetting diagnostic services. Our Vantaa repair facility is equipped with all the necessary testing equipment, and we are here to support you, whether the repair need is significant or minor. If transporting the vehicle to our Vantaa location is not feasible, we can also come to you.
