Our projects

Our partners

We have been able to supply several steam boiler installations for Heineken in Africa, Asia and North America. In addition to new installations, we partly replace existing installations and carry out maintenance and inspections to guarantee high operational reliability and efficiency.

We replaced the steam boiler installation in Vlaardingen for Vopak with two new Viessmann boilers in combination with economisers and flue gas condensers. The whole is heated by Saacke burners with an O² control for correct and efficient combustion.

For Friesland Campina we have renewed the installation in Bornem (BE) with a Viessmann steam boiler in combination with a Weisshaupt burner. To achieve a high efficiency, the flue gases are cooled by means of an economiser and a flue gas condenser.

In Pernis (Rotterdam) we have delivered a 30 t/h Viessmann steam boiler. The installation consists of an economiser and condenser, among other things, so that a high efficiency is achieved.  This installation is also the largest single-fire steam boiler ever delivered by Kuiper en Zonen in the Netherlands.

Boiler inspection

Kuiper en Zonen is the address for supervising your boiler inspection. It is mandatory to have boilers and pressure bodies with a working pressure higher than 0,5 barg inspected. This must be carried out by an authorized notified body (NL-CBI), such as the Lloyd's inspection body. Kuiper en Zonen is responsible for the overhaul of the appendages and safety devices. Kuiper en Zonen also supervises the inspection inspector.

Energy scan

Energy saving is a much discussed topic because it is not only financially interesting to save costs, but it is also less harmful to the environment. To give you insight into the possible savings, Kuiper en Zonen can carry out an energy scan. During this scan, one of our advisors will visit you on location to see what the current situation is. Based on his findings, an advisory report is drawn up in which the possible savings are mentioned. We know from experience that the payback period is generally very short!
