Feedwater & DA/ Condensate Systems

Delval Equipment is a leading provider of Industrial Deaerators, Feedwater Systems, and Surge Tanks. We provide standard and customized systems from various manufacturers including Cleaver-Brooks, BFS and others. Some of our offerings include:

  • Spray:  The spray deaerator has a wide product range from 3,500 #/hr to 500,000 #/hr and higher. It is best used for fairly stable loads and constant water inlet temperatures.
  •  Packed Column: These are generally used for very small boiler applications with a product range of 200 #/hr to 11,000 #/hr. This design is particularly efficient at deaerating very low flow rates.
  •  Tray: This is our most versatile and rugged deaerator unit. It is offered in a range of 3,500 #/hr to 2,000,000 #/hr and higher. This unit can handle severe load swings, varying inlet water temperatures and changing operating pressures while maintaining deaeration efficiency.
  • Duo/Combo Deaerator:  This offering incorporates a deaerator and surge tank in the same vessel. This saves valuable floor space and interconnecting piping can be included.
  • Surge: A surge/transfer system is an important component in a steam system when there is a high volume of condensate returns, or the returns come back in “slugs”. A surge tank will allow this condensate to be collected at varying rates, and transfer the condensate/make-up mix to the deaerator under steady state conditions.
  • Boiler feed and condensate systems: complete with elevated receivers. These are equipped with heavy gauge carbon steel tanks (SS is an option) in standard capacities from 30 gallons to 2000 gallons. Pumps are available in centrifugal or regenerative turbine types and vertical or horizontal configurations to fit your application.

These systems are suitable for all steam boiler applications and can be packaged to your needs with tank, stand, pumps, and a variety of control schematics. The DA equipment often pays for itself very quickly in chemical savings. Proper water treatment is a great way to conserve both energy and water and also to substantially reduce chemicals used for feed water treatment.
