circulation pump dab EVOSTA3
dab EVOSTA3 circulatorDAB's Evosta 3 electronic wet rotor circulators are designed for water circulation in domestic heating and air conditioning systems.
This is the first circulator with IPX5 protection class.
Synchronous motor with permanent magnets and electronic unit with frequency converter, which automatically adjusts the characteristics to the requirements of the system, providing energy savings and protecting the system from hydraulic shocks.
The project provides simple setup. With one button you can sequentially select from nine operating modes: three with proportional differential pressure, three with constant differential pressure and three with constant speed. All models are equipped with an air bleed plug, an automatic degassing function and allow you to manually unlock the motor shaft. Suction and pressure pipes with threads. Impeller made of technopolymer. There is a heat-insulating casing. Pump housing – cast iron with cataphoretic coating, motor housing –stainless steel.
Evosta 3 is equipped with a display to display information about the height in meters of the selected curve, about the power consumption in at the moment in vat-tah, about the pressure at a given moment and the flow rate at a given moment. Thanks to the quick-release cable connector included in the delivery set, Evosta 3 can be connected to the existing electrical network without changing it.
