Brine Corrosion Inhibitor

Don’t let corrosion leave you without the cold! Maintain your calcium chloride brine refrigeration system with AQUAGUARD BI3 brine corrosion inhibitor!

AQUAGUARD BI3 is a chromate-free, all organic corrosion inhibitor and dispersant designed for calcium chloride brine refrigeration systems. AQUAGUARD BI3 contains a complex combination of corrosion inhibitors for maximum corrosion protection of both ferrous and non-ferrous metals including yellow metals (copper and copper alloys such as brass).

Brine systems are also prone to high levels of suspended solids which may settle out over time and create loop restrictions or even blockages. AQUAGUARD BI3 prevents restrictions and blockages through the use of dispersants specially selected to keep these solids suspended and prevent them from agglomerating.

AQUAGUARD BI3 will help keep your brine refrigeration system running efficiently with optimal heat transfer while reducing your maintenance costs and extending the lifespan of the equipment.

  • Extends equipment lifespan.
  • Reduces equipment maintenance costs and ensures efficient operation and optimal heat transfer.
