The project was to control two ammonia refrigerators and six boosters to supply the factory with the required amount of water with controlled temperature and pressure after passing many processes like chlorination, sand filtering, carbon filtering, and reverse osmosis and UV sanitation system.

The system was designed using SIEMENS PLC S7-300 and an industrial PC with touch panel ,all the system parameters were easy access for the operators and technicians with security access protected with passwords, the GUI was designed to simplify monitoring of the system data like boosters status ,flow rate , temperatures, tanks level and pressure. The required pressure was achieved by controlling the VFD’s using PID controllers.
