ALPHA2 L, Model A


Catalog excerpts

ALPHA2 L, Model A - 1

The EEI of ALPHA2 L meets and exceeds the requirements of the EuP 2015 legislation. AFFORDABLE ENERGY EFFICIENCY The ALPHA2 L is a cost-efficient yet high-performing circulator. The reliable pump complies with the strict EuP requirements and is the ideal choice in applications where the well-known UPS has been used to fulfil basic circulator needs. TECHNICAL DATA • s based on the field proven ALPHA2 with more than i 3 million units sold Supply voltage: Flow rate, Q max: Liquid temperature: System pressure, Pmax: Power Range: Ambient temperature: EEI: Enclosure class: Insulation class: • uts energy consumption by up to 80% compared to c traditional pumps • ses as little as 81 kWh per year (based on 150 m2 standard u house with 6840 heating hours per year) • s adaptable to any type of heating system – one- or twoi string – with radiators or under floor heating. 1.
