Wilo-Stratos PARA-C
The most reliable OEM solution for high flow heating applications.
The most reliable OEM solution for high flow heating applications.
The high-efficiency circulator series Wilo-Stratos PARA-C is the high flow OEM solution for heating and solar applications. It offers maximum compatibility thanks to the integration of either internal control modes: Δp-v, Δp-c, n-constant, or external control modes 0-10V, PWM. Its integrated cable and command knob make replacement and commissioning very easy.
