Electronic pressure flow switch for direct control of electric pumps and against dry running. Thanks to the built-in sensor the “HYDROMATIC 2HP” provides a constant flow to the user, avoiding pressure fluctuations. The built-in pressure switch, set at a pressure of 1.5 bar (settable), automatically starts the electric pump, keeping the system pressurised. The “HYDROMATIC 2HP” also detects a lack of water on the suction side of the electric pump, preventing it from running dry and indicating the anomaly by means of a red LED (failure). Thanks to the particular air chamber positioned between the hydraulic unit and the board box, “HYDROMATIC 2HP” is immune to the formation of condensation due to the difference between the ambient temperature and that of the water pumped.
