Deaerators (DAs) are recommended when the steam system requires significant volumes of make-up water that must be treated to remove free oxygen and carbon dioxide from boiler feedwater. Precision Boilers’ Model TR-DA tray deaerators are the best choice for large stream flows where limited condensate return creates a large demand for makeup water. Investing in a Tray DA dramatically reduces the consumption of the costly oxygen-scavenging chemicals typically required to prevent corrosion and premature steam system failure.

Features & Benefits

• Deaerator and storage vessels are 50 psi design and fabricated to include 1/16-in corrosion allowance.
• Mounted on a structural steel stand above the feedwater pumps that are mounted on the base.
• Pumps, motors and controls are pre-piped and pre-wired prior to shipment (pump NPSH requirement determines stand height).
• Float activated make-up water valve adds fresh water to replace condensate lost through the steam loop.
• The DA float assembly is externally mounted, typically sharing the sight-glass water column.
• Control panel mounted on the stand contains fused magnetic starters, switches, lights, alarms, and controls.
• 110-10,000 gallons
