Grundfos ALPHA2 15-50N (130) Hot Water Service Circulator - No fittings

The next generation of A-labelled small circulators. ALPHA2 is the latest and most innovative member of the Grundfos family of high-quality circulators. With ALPHA2, you can stop worrying about complicated pump settings. Simply install the pump and leave it in the factory setting, AUTOADAPT. ALPHA2 will automatically analyse the heating system, find the optimum setting and continue to adjust its operation to changes in demand. The result is optimum comfort and minimum energy consumption. In addition, ALPHA2 is extremely flexible, reliable, and much more compact than any other A-labelled circulator pump on the market.

AUTOADAPT -The factory setting AUTOADAPT, analyses the heating system and automatically adjusts the pump setting to meet the heating demand. AUTOADAPT can be used in 80 % of all heating systems.

Compact design - The innovative design makes ALPHA2 the most compact Grundfos circulator available. With the electronics integrated in the pump housing, installation in very confined spaces is now possible.

A-label -The frequency converter, permanent-magnet technology, and compact stator place ALPHA2 highest on the energy label scheme. ALPHA2 will use up to 80 % less electrical energy than D-labelled circulators.

ALPHA plug - The much appreciated and very popular ALPHA plug is the only plug in the market that offers extremely simple cable connection.

One-touch operation - Intuitive one-touch operation enables simple setting.

LED Display - The easy-to-read LED display always shows the actual power consumption.

Automatic Night SetBack - The night setback function reduces power consumption to a minimum in boilers with power-saving features.

Stainless-steel pump housing - The stainless-steel version, ALPHA2 N, is the reliable choice for domestic hot-water systems and demanding heating systems.
