The new ALPHA2 takes reliability in small domestic circulators to new heights. Even in systems where the operational environment is a challenge, the ALPHA2 will ensure long-lasting trouble-free operation with no risk of blockage. If you want to leave your customers with a completely trouble-free heating solution, the new ALPHA2 is a premium choice. ALPHA2 is versatile and efficient whether you use one of its seven speed, pressure control settings or simply leave it on the factory setting AUTOADAPT™. The ECM motor design reduces energy consumption by 50% and in AUTOADAPT mode, will automatically analyze the heating system, find the optimum setting, continue to adjust its operation to changes in demand and reduce power consumption by up to 85%. This to ensure the lowest possible energy consumption without sacrificing comfort.
