Item description
Version:
Combined station for pressure control and filtration of drinking and process water (neutral) as well as chemical-free cooling water from once-through cooling systems (no circulating water). Protects the pipelines and the system parts connected to them from malfunctions and corrosion damage caused by foreign particles carried in the water, such as rust particles, chips, sand, hemp, etc. The filter element is cleaned by manual backwashing (flushing out the dirt particles) at regular intervals. The rinsed out dirt and the rinsing water can be discharged via a hose or HT pipe.
