Grundfos Alpha3 – Building length 180mm 

Energy efficient circulation pump for heating systems.

Permanent magnet motor (ECM technology) and AUTOADAPT function, which automatically analyzes the heating system, find the optimum setting and continuously adjust the operation to changes in demand.

– Real-time data on pump performance can be transferred to ALPHA Reader, which can use ALPHA3 for balancing radiator and floor heating systems. 
– The AUTOADAPT function automatically finds the optimum set point and thus reduces the energy consumption and setup time. 
– Insulation shells are supplied with the pumps to minimize the energy heat loss in heating and cooling systems. 
– The current power consumption in watts or the current flow in m³ / h is shown on the pump for control purposes. 
– The best energy efficiency index (EEI) on the market provides the largest energy savings per year

– Automatic night immersion function that further reduces energy consumption if the boiler supports this function. 
– Easy selection between three constant pressure curves, three proportional pressure curves or three fixed speeds using only one button. Easy and quick setup. 
– Manual summer operation mode. Saves energy in the summer – consumption <0.8 w – and is always easy to start when the heating season starts.
