Service abroad – SLA

Kuiper & Zonen supplies installations worldwide and also ensures that they are optimally maintained.


By having preventive inspections carried out, any irregularities can be detected at an early stage. This minimizes potential incidents and loss of yield, resulting in a safe, reliable installation. A Service Level Agreement includes an annual boiler inspection and two burner inspections per year.

  • Boiler inspection: we inspect the boiler from the outside and inside (flue gas side and water side), we also take the entire boiler house with us where all components are discussed, such as degasser, economizer, pumps, etc. We act as a notified body, since not every country has a NOBO.

  • Burner inspection: we inspect the burner, carry out maintenance and replace parts where necessary (if present). We also optimize combustion for the right balance between heating costs and emissions.


After an inspection, we write an extensive report, describing the current status with, of course, practical advice on how the boiler can be used optimally with high operational reliability. We can also advise whether and which spare parts should be kept in stock to minimize downtime. If repairs or adjustments are required, our specialized engineers can carry them out for you.

Service all over the world

Kuiper & Zonen is not only active in the Netherlands, but also delivers complete installations and offers service all over the world. For installations abroad, we offer a Service Level Agreement (SLA). The installations we install are often delivered in combination with an SLA, but we increasingly offer our service activities for installations that are not delivered by us. Our engineers and inspectors have seen countless boilers, so they can quickly make a correct diagnosis and advise you on how to keep the boiler in optimal condition.
