Hong Kong Aero Engine Services Limited (HAESL) is a joint venture company between Rolls-Royce plc and Hong Kong Aircraft Engineering Company Limited (HAECO). The annual throughput have approximately 250 engines. They have overhauled more than 3,700 Rolls-Royce engines since HAESL's establishment.

Most of the engine parts after maintenance require to have a plating process for finishing. Thus the plating process lines are one of the important process control system.

In this project, there is 2 plating process lines require to replace the PLC Control System. We supplied and installed 1 number of Main Control Panel with Siemens PLC & Siemens Touch Panel and number of Local Control Panels for each of the plating process line. All the old temperature controllers are replaced with the new temperature control function using PLC to control. PLC also counting the number of process tanks are being opened and also control the speed of the extraction system.
