SCREEN FILTRATION TECHNOLOGY

Filtration
The B-Series Screen Filtration models utilizes a fine screen that purifies the flow by separating smaller particles from the water. The E, SE, and H-Series models untilize a combination of a course screen and a fine screen for the removal of particles.

As more water flows through, impurities build up on the screen. As impurities on the screen accumulate, a pressure imbalance is built up between the internal section of the screen and its external section resulting in an initiation of the cleaning process.

Cleaning Process
When the difference in pressure reaches the preset value on the electronic control unit, a series of events is triggered while water continues to flow to the system units. The flushing valve opens, pressure is released from the hydraulic piston, and water flows outside. Pressure in the hydraulic motor chamber and the dirt collector is significantly lowered, and the dirt collector nozzles begin a suction process. The water flows through the hydraulic motor which rotates the dirt collector around its axis. The pressure rlease from the piston and the high pressure inside the filter causes linear movement of the dirt collector. The combination of the linear movement and rotation efficiently cleans the entire internal screen surface. The flushing cycle takes 5 seconds. The flushing valve closes at the end of the cycle and the increased water pressure returns the system to its initial position. The filter is now ready for the next cycle, with clean and filtered water flowing through the 'Outlet'.

General Description of the Electronic Control System
The electrical system controls the cleaning process through the differential pressure indicator, that closes a circuit and triggers the electronic control unit controlling the opening and the closing of the flushing valves via the solenoid valve. The flushing cycle, which takes a total of 5 seconds, resumes its operation whenever the difference in pressure reaches the preset pressure value set on the differential pressure indicator. If the difference in pressure remains unchanged after one cycle, another cycle will start after a delay of 25 seconds.
