Deaerators

Deaerators are used for reducing the content of oxygen, carbonic acid, and air in the water, for treatment of make-up water for steam boilers and district heating centrals, and for deaeration and deoxidization of circulating water. 

Advantages

Reduction of oxygen and CO2 minimize the risk of corrosion. All deaerators are produced in materials which ensure a long life, high operational reliability, and a minimum of maintenance of your plant.

Plant description

EUROWATER produces several types of deaerators:

  • Thermal deaerators
  • Vacuum deaerators 
  • CO2 degassers
  • Membrane degassers
Thermal deaerator for boiler feed water. The shown deaerator has a capacity of 4 m³/h.

Thermal deaerators

Flow rate: Up to 40 m³/h.

Are used for pretreatment of feedwater for steam boilers. The oxygen content is reduced to very low values. Can be insulated with mineral wool and covered with aluminium plates. The plant is constructed according to the EU pressure tanks directive of 29 May 1997 (97/23/EF) (PED) and is delivered approved with CE marking.

Vacuum deaerators

Flow rate: Up to 50 m³/h.

Are used for treatment of make-up water and circulating water in heating centrals. The oxygen content is reduced to less than 0.1 mg/l. Possibility of construction in electroplated and stainless steel. 

 

CO2 degassers

Flow rate: Up to 50 m³/h.

Are used in connection with dealkalizers or UPCORE demineralization plants.

 

Membrane degasser

Flow rate: up to 40 m³/h. 

Removal of CO2 and O2. Used in connection with RO units, mixed-bed units and EDI units. Read more about membrane degassing units here
