Description

With the new ALPHA2, you no longer need to worry about complex settings for the circulator. Simply install the circulator and leave it on the factory setting, AUTOADAPT. The new ALPHA2 will automatically analyze the heating system, find the optimal setting, and continue to adjust its operation when parameters change.

Features and benefits:

  • Better performance with top market efficiency (EEI≤0.15) in a more compact design.
  • Flow indication for troubleshooting and balancing.
  • AUTOADAPT selects the best performance curve for efficiency and ease.
  • Innovative terminal box facilitates access and simplifies the connection of the circulator.
  • Equipped with an insulating shell.

Usage:

GRUNDFOS has made new and very significant design changes that now allow you to use the new ALPHA2 in cooling applications with a minimum temperature of the circulating liquid at +2 °C.

    This review is about maximum pressure head (m): 8 m, connection diameter: 32 mm

    I have been using this circulator for about three months. However, I have the same one in another application in my house for 10 years.
    It is the best circulator available, depending on the use it will be installed for.
    What makes it a valuable product is that this specific circulator can bypass obstacles in a circuit, such as very small pipes with a diameter of 8mm or many angles or small connections.
    I used it in solar panels with copper pipes with a diameter of 8mm and hot water supply up to the heating collector. You can see it on YouTube, solar heating.
