Rust-Bloc - Corrosion and Scale Inhibitor
Corrosion and scale inhibitor containing a copper specific inhibitor. Compatible with non-oxidising biocides.
Rust-Bloc is an effective corrosion and scale inhibitor for open recirculating cooling water systems. Rust-Bloc also gives excellent corrosion protection in closed condenser loop, chilled and low temperature heating hot water circuit systems.
Directions for Use
Open cooling water systems
Initial dose: 500mL of Rust-Bloc per 1000L of water. Maintenance dose: 300mL of Rust-Bloc per 1000L of water.
Closed circuit systems
Maintain between 1500mL to 2500mL of Rust-Bloc per 1000L of system water.
Monitor Rust-Bloc by testing the level of Sodium Nitrite and multiple by two. Consult a HydroChem representative for specific recommendations for your application.
Water treatment of small cooling tower systems should include a secondary biocide and inhibitor program. The use of Bio-Bloc is recommended. Refer to product bulletin instructions.
