TECHNICAL DATA SHEET
ALPHA1L is the new and only universal circulator capable of replacing 95% of Grundfos circulators currently installed in heating systems and boilers.
Thanks to its compact design, easy connection to signal cables (PWM), and high temperature tolerance, the ALPHA1 L fits seamlessly into most heating systems equipped with Grundfos circulators.
This means you can easily replace broken or energy-inefficient circulators without having to carry excess spare parts around with you, saving space, time and money.
Grundfos Alpha1 L 15-60/130 High Energy Efficiency Circulator
The new ALPHA1 L universal circulator is suitable for multiple applications:
Boilers
Underfloor heating systems
Mixing unit and boiler kit
Domestic hot water recirculation systems
Biomass heating
