DAB Evosta 3 is an electronic circulator with a “wet” rotor, designed for water recirculation in heating and air conditioning systems in domestic and residential installations.
This is the first circulator with an IPX5 protection rating. Equipped with a synchronous motor with permanent magnets and frequency-controlled electronics that automatically adapts performance to the needs of the system, ensuring energy savings and protection against water hammer.
Easy to set up: a sequential button allows you to switch between nine operating modes - three proportional pressure modes, three constant pressure modes and three constant characteristic modes.
Included - thermal insulation covers. Pump body made of cast iron with cataphoretic coating, motor body made of stainless steel.
Evosta 3 is equipped with a display that shows: head (in meters) of the selected characteristic, current power consumption (W), instantaneous head and current flow rate.
The included descaling cartridge keeps the motor shaft in perfect condition, preventing the formation of limescale deposits that can occur inside the circulator in the presence of air bubbles during initial start-up.
