This Indian customer applied the rectifiers to brass plating tanks and cyanide copper plating processes. Customer feedback indicates that our rectifiers feature advanced automatic sensing capabilities: when the plating rack is removed from the tank, the equipment automatically cuts off the current output; and when the rack is reinserted, the current reading immediately resumes and normal operation begins. This intelligent design effectively improves operational safety and avoids process risks caused by misoperation.

“The rectifiers are amazing,” the customer stated in a communication, “Your machine seems better than what type of IGBT made locally.”

In the future, we will continue to uphold the philosophy of “technological leadership and superior quality,” providing global customers with more efficient and intelligent electroplating power supply solutions.

Currently, the rectifiers used in the factory are SCR-type. These units lack a water circuit system, which presents challenges given Dubai’s extreme summer temperatures, reaching up to 55°C. However, there is a working room equipped with air conditioning to maintain the rectifier environment temperature below 40°C, ensuring stable operation.

Considering the specific requirements for zinc plating, our engineers recommended a 12V 2000A air-cooled IGBT rectifier as the ideal solution. The advanced IGBT rectifier is not only energy-efficient but also highly reliable for the demanding conditions of the surface treatment industry.

In January 2024, our team visited the factory in Dubai to discuss further cooperation. The proposed plan involves replacing six outdated SCR-type rectifiers with cutting-edge IGBT rectifiers and building a comprehensive water circuit system. This upgrade will significantly enhance the efficiency and reliability of the electroplating process, particularly for zinc plating applications.

This project serves as a representative case in the surface treatment industry, demonstrating how modern IGBT technology can optimize electroplating operations while meeting the demands of challenging environments.
