200A 12V 3-Phase Pretreatment Rectifier for Electrocleaning and Activation

    The Pretreatment Rectifier from Gaohui Rectifier supports electrocleaning, acid activation, and rinsing stages on plating lines. This Pretreatment Rectifier delivers stable DC for surface preparation. Furthermore, the Pretreatment Rectifier handles continuous duty in aggressive chemical environments. Therefore, line operators count on it daily.

    Cooling: Forced Air | Application: Electrocleaning & Activation | Ripple: ≤3% | Input: 3-Phase

    Applications and Use Cases

    The 200A 12V rectifier powers alkaline electrocleaning tanks of 1000L to 2000L capacity. It removes oils and oxides from steel and zinc parts before plating. Specifically, a typical electrocleaning cycle runs at 5 to 10 A/dm² for 3 to 5 minutes. Furthermore, the rectifier supports both cathodic and anodic cleaning.

    Moreover, this rectifier serves acid activation and reverse-current desmutting stations. Consequently, workpieces arrive at the plating stage fully active. The 3-phase input ensures stable output under heavy workshop loads.

    Furthermore, Gaohui builds pretreatment rectifiers for both manual and automated lines. The 3-phase input provides enough current for 1000L to 2000L cleaning tanks. Consequently, job shops and OEM lines both rely on this model.
