Description Specification Downloads Description The new MCE/C inverters are the latest technological challenge in the DAB inverters universe. They constitute the new generation of inverters for use with circulator pumps and stand out for ease of use, power, and simplicity of installation and management. MCE/C inverters are designed for use with circulator pumps to enable simple control of differential pressure, thereby adapting pump performance to match effective system requirements. The solution of mounting on the motor base greatly simplifi es installation of the pump with MCE/C in minimal times. Ease of programming is guaranteed by the use of an interface similar to DAB Dialogue and a graphic display. MCE/C inverters feature dual microprocessor architecture to guarantee maximum efficiency and reliability. Sturdy and reliable construction is combined with modern and innovative styling to complete the product also in terms of aesthetics. MCE/C inverters protect the pump thanks to integrated safety devices. They are also able to prolong the useful lifetime of

Description Applications and Industries Downloads General Description 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 on 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. MThe GRUNDFOS ALPHA2 is designed for circulating liquids in heating systems. Pumps with stainless steel pump housings can also be used in domestic hot-water systems. The GRUNDFOS ALPHA2 is suitable for: Systems with constant or varying flows where it is desirable to optimise the pump duty point Systems with a varying flow-pipe temperatures Systems where night setback is required. Features and benefits EUP compliant - one of the most energy efficient circulators on the market Compact design, with control box well integrated into the pump head AUTOADAPT control mode as the default setting, suitable for
