Deaerators

Deaerators from Kuiper en Zonen achieve a residual oxygen concentration of 0.02 mg/l without the addition of chemicals. A deaerator saves money, depending on the process and the amount of steam used.

Inside deaerator

Kuiper en Zonen develops and sells its own deaerators in cooperation with Viessmann. A deaerator expels as must oxygen and free carbon dioxide as possible from the feedwater, because these gases can cause corrosion in the boiler, as well as in the steam and condensation installation. Kuiper en Zonen guarantees an outflow of oxygen and free carbon dioxide of 0.1 mg/litre. This page shows a project at a medical research institute where we have installed deaerators.

If you use our deaerators, you need less chemicals for your operational process. Our deaerator is, for example, ideal for use in the food industry. We can usually supply from stock. We also lease and service deaerators.

Deaerators reduce the oxygen concentration

Corrosion is formed as the result of oxygen in the water. Normally, cold water (10 °C) has an oxygen concentration of 15 g/litre. To protect your steam boiler from corrosion, an oxygen concentration of less than 0.1 mg/litre is required during the process. This can be achieved with the use of very few chemicals, because a deaerator reduces the use of chemicals by up to 80%.

Spray deaerator or cascade deaerator

Spray deaerators guarantee to reduce the oxygen concentration to less than 0.1 mg/litre. A spray deaerator is an interesting option for a boiler with a capacity of 2,000 kg of steam per hour or more. The water is spread across the steam chamber by the deaerator by means of one or more spray nozzles. Cascade deaerators can reduce the oxygen concentration even more, to less than 0.02 mg/litre.

Advantages of deaerators from Kuiper en Zonen

Deaerators from Kuiper en Zonen offer many advantages to your steam boiler installation:

•             A cost reduction thanks to the use of fewer chemicals.
•             A low oxygen concentration because the water remains in the tank for longer.
•             A long service life thanks to the specific low-voltage welding process used for the construction.
•             High operational reliability thanks to the use of high-quality components, such as level control, low-water protection and pressure control.
•             The deaerator, spray tank, chemical dosing unit and other items are mounted on a single frame, so the installation on site requires little work.
