Circulator pump EVOSTA2 75/180, modulated output, PWM control 31091

High-performance circulation pump for NIBE heating systems

The EVOSTA2 75/180 circulation pump is an advanced solution for heating installations, equipped with modulating performance and PWM control. Thanks to intelligent rotational speed regulation, the device automatically adjusts its operation to the current needs of the system, ensuring optimal circulation of the heating medium with minimal energy consumption.

Advanced PWM modulation technology

PWM (Pulse Width Modulation) control enables precise control of the pump's rotational speed through modulation of the power pulse width. This technology allows for smooth performance regulation across a wide range without the characteristic jumps typical of traditional fixed-speed pumps. Modulating performance eliminates the problem of system overload during periods of reduced heat demand, resulting in significant energy savings.

The intelligent control system automatically detects changes in the installation's hydraulic resistance and appropriately modulates the pump's power. This ensures the device always operates at the optimal efficiency point, minimizing electrical energy consumption while maintaining full heating system functionality.

Compatibility with NIBE systems

The EVOSTA2 75/180 pump has been specifically designed for cooperation with F2040-16 series, AMS 10-16, and F2120-16 and -20 equipped with SMO (System Management Option) or HBS (Heat Booster System) modules. This precise compatibility guarantees seamless integration with existing NIBE installations and full functionality of management systems.

Cooperation with the SMO module enables centralized control of the pump's operation within a comprehensive heating system, allowing synchronization of its action with other installation components. Integration with the HBS system ensures optimal working conditions for pumps supporting the heating medium reheating processes.

User and operational benefits

Modulating performance brings tangible economic benefits through significant reduction in electrical energy consumption compared to fixed-speed pumps. The system automatically adjusts power to the actual needs of the installation, eliminating unnecessary energy losses resulting from excessive medium circulation.

PWM technology also ensures quieter operation of the device thanks to smooth rotational speed regulation and reduction of mechanical vibrations characteristic of traditional solutions. Reduced mechanical loads translate into extended pump lifespan and decreased maintenance requirements.

The compact design with a 75 mm connection diameter and 180 mm mounting height facilitates installation in various system configurations while maintaining full functionality and reliable operation even in demanding conditions.
