Wet rotor electronic circulator designed for water recirculation in heating and conditioning systems in residential building service. It is the first circulator with IPX5 protection class. Synchronous permanent magnet and electronic motor with variable frequency drive that automatically adapts the performance to the demands of the system allowing energy savings and protecting from water hammer. It is designed for a simple configuration: a sequential key allows to scroll between the nine operating modes, three with proportional pressure, three with constant pressure, three with constant curve. All models have a brass vent plug, the automatic degassing function and allow the manual deblocking of the motor shaft. Threaded suction and delivery ports. Technopolymer impeller. Insulation shells included. cataphoretic cast iron pump body, stainless steel motor casing. The circulator is equipped with a display to view the height in meters of the selected curve, the instantaneous absorption of power in watts, the instantaneous head and the instantaneous flow rate. Thanks to the new interchangeable power plug the Evosta 3 can be powered by the connectors of other brands without redoing the electrical connections. The included calcium removal cartridge keeps the motor shaft in perfect condition, preventing the normal formation of limescale that it can be generated inside the circulator if some air bubbles are present during the first installation.
