BoilerAid 385

Protect steam boilers from oxygen corrosion and scale buildup. Boiler Aid 385 is a 90% active, ultra-concentrated liquid treatment that combines tannin-based oxygen scavengers, reducing agents, and polymeric dispersants. It prevents oxygen pitting and corrosion in boiler feedwater systems while controlling hardness and scale formation. Its non-sulfite chemistry does not increase dissolved solids or conductivity, making it ideal for high-efficiency and food-grade applications.  Key Benefits  Prevents oxygen pitting and metal corrosion in boilers  Controls calcium, phosphate, and iron oxide scale deposits  Reduces dissolved oxygen without contributing to TDS or conductivity  Replaces sulfite-based treatments for safer handling and cleaner operation  Includes volatile neutralizing amines to protect steam and condensate lines  FDA-acceptable for use in food, drug, and cosmetic plant applications  Where to Use  Steam boilers and boiler feedwater systems  Deaerators and condensate return systems  Product Details  Type: Oxygen scavenger and corrosion inhibitor  Form: Liquid  Color / Appearance: Brown liquid  pH Range: 12.0+ (1% solution)  Dosing & Application  Feed Location: Add to the deaerator storage section or directly to the boiler feedwater tank below the water line.  Initial Treatment: Apply 30 ppm per 1,000 gallons of makeup water (≈1 lb per 4,000 gallons) to achieve 300 ppm in the boiler.  Control Testing: Maintain 75–150 ppm tannin/reducing agent using a 987L drop count test kit (1 drop = 10 ppm tannin).  Boiler Alkalinity Control: Maintain P-alkalinity ≥300 ppm and free hydroxide (OH) ≥200 ppm in the boiler water.  Condensate Return pH: Maintain between 7.5–9.0 for optimal system protection.  Packaging Options  Available in 1-gallon jugs, 5-gallon pails, 15-gallon drums, 30-gallon drums Bulk delivery available upon request
