Sediment separator; a protective device that separates rust, lime, welding slag, and other particles involved in the circuit of heating, cooling, and process water installations, collecting them in the lower part of its body. As the flow passes through the straining element inside the body, large and medium-sized particles are captured, sediment accumulates in the sludge lower chamber and can be discharged without stopping the system with the drain valve. This significantly reduces the risk of clogging and wear in valves, pumps, heat exchangers, and control elements.
