WTP H430


WTP H430 is a halogen and oxidizer resistant corrosion inhibitor designed for soft to medium hardness waters that have corrosion potential.

WTP H430 contains background scale inhibitors to protect against hardness slippage or over-concentration of system water. WTP H430 also contains a synergistic blend of phosphonocarboxylate and sodium molybdate to provide excellent corrosion inhibition.


WTP H430 is dosed to maintain a system reserve of 100ppm to 150 ppm.

A Molybdate test is available to determine reserves in the system (WTPTK105).

Molybdate as MoO4 X 12.5 = Reserve as product
