The TrayMaster deaerator is a pressurized, low-maintenance system designed to remove dissolved oxygen in boiler feedwater and eliminate carbon dioxide. This deaerator is offered in vertical and horizontal tray configurations.

  • Product Overview
  • Related Resources
  • Applications
  • Less mechanical movement of deaerator components
  • Two-stage deaeration in a common vessel
  • Exceeds ASME recommendations for oxygen level
  • Integral level control automatically introduces cold water makeup
  • Supplement condensate only when necessary to meet boiler demand
  • On/off or variable speed pumping


The TrayMaster deaerator design is recognized as the most versatile and efficient method of reducing dissolved oxygen content in boiler feedwater to levels less than .005 cc/liter (7 ppb) while also removing carbon dioxide. Built of corrosion-resistant alloys for lifetime service, the deaerator employs advanced principles of gas removal proved to be the most effective and economical to every boiler owner. Vessels are all factory tested, then assembled and broken down for shipment and ease of installation. All of Cleaver-Brooks deaerators can be equipped with a wide range of options from basic manual controls up through full advanced digital operation depending on the needs of the system. Equip your Deaerator with the ADAC control system to provide the most advanced operation of your feed systems.
