Grundfos circulator alpha2 25-60 180 mm
ALPHA2 is able to withstand the tough conditions in a heating system, and with four newly added features, it just got even tougher:Robust start-up:Shakes free any impurities before the pump starts at the beginning of the heating season.Summer mode:Adjustment of the pump’s performance in the summer to the warmer temperature outside – giving customers extra energy efficiency.Magnetite resistance:Ensures that no small pieces of metal get stuck in the pump’s vital parts when they are magnetised.Dry-running protection:Makes sure the pump never runs without liquid in the system - add to that unrivalled energy efficiency, easy installation and the fact that ALPHA2 covers both your heating demands and up to 90 % of your air-conditioning and cooling demands.The GRUNDFOS ALPHA2 is suitable for:• Systems with constant or varying flow• One pipe systems• Two pipe systems• Underfloor-heating• Domestic hot-water recirculation• Systems where night setback is required.Features and benefits• Better performance with market leading efficiency (EEI0.15) in a more compact design• New flow meter for trouble-shooting and balancing• AUTOADAPT selects best performance curve for efficiency and comfort• Innovative plug simplifies pump connection• Insulation shells included.
