Why maintenance saves you money

Emergency power generators, also known as backup power systems (BPS), are devices used for generating electricity to sustain the power supply for essential consumers in the event of a power grid failure by the utility provider. Automatic start-up and automatic consumer switching are mandatory for all systems that require a backup power system by law.

For the reliable operational readiness of the emergency power generator in case of an emergency, regular maintenance is absolutely necessary. Our high-performing service team is available to you at all times. Our service technicians are specialists in the field of emergency power technology. Whether it's mechanical or electrical, we always have the appropriate solution for your problem.

Condensates form, which contaminate and render the oil unusable. Additionally, regulators can get stuck and hoses can become more porous, leading to significantly more expensive and larger repairs later on.

Almost all engine manufacturers require regular maintenance for new backup power systems, as warranty claims may be voided otherwise. We specialize in maintenance according to manufacturer specifications. Our experience covers a variety of engines from different manufacturers, such as:
