AUTOMATIC SELF CLEANING WATER FILTERS:
It is designed to remove solid and sand particles from the river and seawater used for cooling or industrial purposes. The filter is manufactured with a filtration rating from 1000 to 3000 microns and is specifically indicated for the protection of heat exchangers because it can operate 24 hours a day without local surveillance. The flow rate of the water is guaranteed also when the filter is in back-washing mode. The back-washing is started by means of a DP signal and controlled by a timer.
