DAB Evosta2 electronic circulator for domestic and residential systems
The DAB Evosta2 40-70/130 is a compact and efficient electronic circulator designed for water recirculation in heating and air conditioning systems. Thanks to the synchronous motor with permanent magnets and electronic inverter control, it automatically adjusts performance according to system requirements, ensuring energy optimization, silent operation, and long life.
It is the ideal solution for replacing old three-speed circulators, offering compact dimensions, easy installation, and superior performance.
Energy efficiency and protection against water hammer
The integrated electronics automatically modulate the pump speed, avoiding energy waste and ensuring constant thermal comfort. The system also reduces water hammer, protecting the system and improving overall efficiency.
With optimized consumption and intelligent flow management, Evosta2 significantly contributes to reducing operating costs.
Intuitive control panel with 9 operating modes
The circulator features a control panel with a MODE button that allows you to choose from nine configurations:
- 3 proportional pressure modes
- 3 constant pressure modes
- 3 constant speed modes
The desired configuration is displayed via segment light indicators, offering a clear, simple, and immediate interface.
Robust construction and high-quality materials
Evosta2 combines the solidity of the mechanical circulator with the advantages of advanced electronics. The structure includes:
- cast iron pump body with cataphoresis treatment
- steel motor casing
- technopolymer impeller
- ceramic motor shaft, mounted on ceramic bushings
- stainless steel rotor sleeve, stator sleeve, and flange
- graphite thrust ring
- EPDM sealing rings
- brass air vent plug
The IPX5 protection rating makes the electronics water-resistant, ensuring reliability even in critical environments.
The anti-scale cartridge keeps the shaft in perfect condition over time, preventing blockages due to air or internal deposits.
Anti-blocking system and easy maintenance
The pump is equipped with an automatic anti-blocking function and allows manual shaft unlocking if necessary, a feature highly appreciated during maintenance.
Thanks to the internal motor protection, it does not require external overload protection devices, further reducing installation time and costs.
