Art.-Nr. 99371950/GR - Circulator pump ALPHA3 15-60 130 - GRUNDFOS OEM : 99371950

High efficiency circulator pump with wet rotor designed for circulating liquids in heating installations. With a much lower energy efficiency Index (EEI) than the ErP reference, it can provide significant energy savings. The ALPHA3 has a built-in Bluetooth connection and is fully controlled by a smart device through the Grundfos GO Remote application. It provides step-by-step support for the configuration, maintenance and commissioning of the circulator pump. The ALPHA3 communicates with the Grundfos GO Balance application directly, which allows installers to perform quick and easy hydraulic balancing. The AUTOADAPT function integrated in radiator and floor heating mode continuously adapts the circulator pump's performances to match real heat requirements, in other words to the size of the installation and the change in demand over the year. The AUTOADAPT function will find the setting that gives optimum comfort with minimum energy consumption. Commissioning is fast, safe and easy. CHARACTERISTICS: Radiator mode with AUTOADAPT: the simple choice for twin-tube heating installations. Floor heating mode with AUTOADAPT: the simple choice for floor heating installations Combined radiator and floor heating modes for combined installations In planning mode and summer mode, a real-time clock allows you to select the moment at which the circulator pump should operate without saving energy. User-friendly interface - the circulator pump is fully controlled from the Grundfos GO Remote application Low maintenance due to the wet rotor design and the use of quality components The ALPHA connector makes the electrical installation fast and easy Insulation shells are supplied with the circulator pumps to minimise heat losses in heating installations Furthermore, the circulator pump has three control modes with incremental adjustment of the set-point, which allows the circulator pump to be adjusted to a given set point: Proportional pressure regulation Constant pressure regulation Constant curve mode The display shows the actual electrical consumption in Watts or the actual flow in m3/h. The LEDs indicate the real operating status. The design of the circulator pump and the materials chosen contribute to its long life. The circulator pump self-bleeds through the installation, making start up easier. The compact design, including a circulator pump head with integrated control box, is suitable for most installations. The circulator pump and the motor form a complete unit without mechanical packing. The bearings are lubricated by the pumped fluid. These characteristics assure maintenance-free operation. The circulator pump can operate in three control modes with incremental adjustment of the set point. The circulator pump body is made of cast iron. The circulator pump body and head have an electroplated coating to improve corrosion resistance. The circulator pump is equipped with a synchronous permanent magnet motor characterized by high efficiency. The speed of the circulator pump is controlled by a frequency converter built into the control box. Liquid temperature range: 2?110°C Ambient temperature range: 0...40°C Automatic changeover to night conditions
