T.A.S.C. VIII Automatic Rectifier

C$ C$

The Corrpro® T.A.S.C. Series rectifier is designed to provide accurate and economical corrosion control for the submerged surfaces of steel water storage tanks and water/wastewater treatment units. The T.A.S.C. VIII is designed by NACE accredited cathodic protection engineers for optimum performance in accordance with ANSI/AWWA D104, Type A, IR Drop Free control standards.

The T.A.S.C. rectifier automatically monitors and adjusts the DC output required for optimum corrosion control. It is equipped with an automatic potential limit which is adjusted to maintain AWWA D104-97 and NACE criteria for optimum cathodic protection corrosion control while preventing over or under protection of the coated surface. Superior design, engineering and operation provide owner/operators with long life, low maintenance performance.

The standard digital display meters facilitate ease of monitoring with performance indicator lights on the front cabinet available as an optional extra feature. Each T.A.S.C. rectifier is factory tested to ensure quality workmanship and performance.
