The Air-Cooled Hard Anodizing Rectifier from Gaohui Rectifier delivers 20A at 80V for air-cooled hard anodizing. This Air-Cooled Hard Anodizing Rectifier powers a wide range of oxidation racks with stable DC or pulsed output. Furthermore, the Air-Cooled Hard Anodizing Rectifier uses air cooled IGBT stages that hold tight output stability under full load. Consequently, oxidation shops rely on it for uniform, repeatable coatings. Moreover, surface-finishing facilities select this Air-Cooled Hard Anodizing Rectifier for its air cooled design and 20A 80V capacity that keeps deposition rates predictable. Consequently, production planners factor it into daily schedules without derating concerns.
Cooling: Air cooled | Application: Air-Cooled Hard Anodizing | Ripple: ≤5% | Interface: RS485/PLC
The 20A 80V rectifier is engineered for hard anodizing of aluminum, producing thick wear-resistant anodic films. It serves jigs, hydraulic cylinders and automotive parts requiring 20–100 micron hard coat. For example, a line can anodize piston rods and guide rollers in a single pass. Furthermore, tight current control holds coating thickness steady across racks. Moreover, low ripple promotes a hard, dense film. In addition, the RS485, optional PLC interface ties it to line automation.
Moreover, this rectifier supports timed cycles for repeatable film build. In addition, water-cooled cooling sustains high-volume shifts without derating. Consequently, plants rely on it for hard chrome-free wear coatings. Moreover, maintenance teams value the accessible IGBT modules. Finally, Gaohui tunes the ramp and current limits to each customer's tank.
