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 SP-DA spray deaerator relies on internal spray valves, a vent condenser, and fresh steam to allow the make-up water to release the O2 and CO2 naturally. This eliminates the need to rely on costly oxygen-scavenging chemicals to prevent corrosion leading 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 with pumps mounted on the base
• 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
• 140-6,000 gallons
