We carry out revisions and upgrades to keep your system in optimum condition and extend its lifespan. This applies to both the electrical and mechanical parts of the system as well as the control system software.
These revisions and upgrades are scheduled and carried out by our team of 35 in-house trained specialists.
From minor periodic maintenance to major overhauls. Zwart evaluates your system based on your requirements and develops the appropriate maintenance and revision program.
Still fit for purpose?
Should the power requirement have increased over time we can provide solutions to increase capacity of the emergency power system accordingly. During regular maintenance visits the engineer can evaluate the required power relative to the system’s capability and discuss the upgrade options with the customer to ensure no unpleasant surprises.
Life Extension
Typically at around 10 years into the life of the system we carry out a major revision of the system to ensure it is fit to perform reliably for at least another 10 years. This usually involves a strip-down of the major parts, preventative replacement of critical components and a comprehensive inspection of all major elements of the engine.
Statutory inspections
Most countries mandate inspections of fuel systems to ensure there is no risk of leakage or fire. This is an important and time consuming task, often made more challenging by the routing of the fuel system and, in some cases, the use of underground tanks. Zwart has the resources to perform these statutory checks as and when required.





















When it matters most
Reliable backup from Zwart
With over 7,000 projects in more than 50 countries in the field of emergency power and off-grid solutions, Zwart has an outstanding track record, throughout Europe, Africa and the Middle East. There is a reason why the biggest data centres and financial institutions in Europe as well as major airports and mobile networks rely on Zwart; Our 100 in-house trained professionals are qualified to design, engineer, realise and maintain integrated and complete systems for emergency power supply. And we have been doing so for over 90 years.
We set the bar high for ourselves and demand the same from our partners and suppliers; we work exclusively with premium quality products and service providers, we assemble the systems at our own 6,000-square metre site in Ijmuiden and subject them to a rigorous testing and inspection program before releasing them. Our customers also receive the same high level of attention through training and knowledge sharing our training centre equipped with a state-of-the-art simulator.
