Boiler Support : Deaerators

Critical equipment for boiler water systems

CRG offers a variety of deaerators sized from 5,000 pph to 250,000 pph. Deaerators are guaranteed to remove oxygen in boiler feedwater to .005cc/liter. Each unit is designed, constructed and stamped in accordance with the ASME Code of Pressure Vessels and inspected and registered with the National Board of Boiler & Pressure Vessels. This unit may be built with single or multiple pump applications using only name brand pumps, primarily Grundfos. (others available upon request)

Advantages of using a deaerator

• removes carbon dioxide as well as oxygen

• eliminates the need of expensive oxygen scavenger chemicals, while improving on boiler room efficiency
