Deaerators & Boiler Feed Systems

What Is A Deaerator?

Deaerators are mechanical devices that remove dissolved gases from boiler feedwater through a heating, agitation, and liberation process. Deaeration protects industrial steam systems from the effects of corrosive gases by reducing the concentration of dissolved oxygen, carbon dioxide, and other noncondensable gases to a level where corrosion is minimized.

Why use a Deaerator?

Longer Equipment Life

Deaeration reduces oxygen and carbon dioxide corrosion in the boiler and associated piping
Using preheated feedwater reduces the chance of thermal shock caused by the expansion and contraction of heating surfaces

Lower Operating Costs

Mechanical deaeration provides a fixed method of eliminating oxygen without the use of the expensive chemical alternative
Continuous deaeration reduces total CO2 in the steam system, ultimately lowering maintenance costs

Stop throwing money down the drain, watch our deaerators pay for themselves!

Types of Sellers’ Deaerators

Pressurized

Sellers Pressurized Series offers industry leading reliability and durability with its Pressurized Series of deaerators, ideal for applications where gravity returns are not present.

Designed to increase the longevity of boiler piping systems by reducing O2 and CO2 content in boiler water, Seller’s pressurized deaerators can reduce the level of these dissolved gases below 0.005 cc’s per liter. When compared to our Atmospheric Series of deaerators, the Pressurized Series is ideal for applications where blend temperatures exceed 180° F.

Atmospheric

Sellers offers industry leading reliability and durability with its Atmospheric Series of deaerators, ideal for applications over 3000 HP or where a high percentage of make-up water is present.
Designed to increase the longevity of boiler piping systems by reducing O2 and CO2 content in boiler water, Seller’s pressurized deaerators can reduce the level of these dissolved gases below 0.005 cc’s per liter. When compared to Seller’s Pressurized Series of deaerators, the Atmospheric Series is ideal for applications where there the end user anticipates a high percentage of make-up water or gravity returns.

Oxygen Rating: .005 cc/liter; 227°F
Certifications: ASME UL
Warranty: 1.5 Or 15-Year (Shell) / 1.5-Year (Parts)

What Is A Boiler Feed System?

Boiler Feed Systems

A boiler feed system is an assembly that collects condensation and pumps feed water into a boiler. Seller’s boiler feed systems help prolong the life of boilers and maintain peak efficiency. Additionally, they provide more economical options to deaerators.
