Grundfos circulator Alpha 2 32-80 180 cod. 99411263
Grundfos Variable speed circulator ALPHA2 32-80 180 code 99411263 ALPHA2 32-80 180 Product code 99411263 Useful to Heating in commercial buildings Home heating Industrial heating The Grundfos ALPHA2 series consists of highly efficient circulation pumps, designed for heating and air conditioning systems. It is equipped with the AUTOADAPT function which automatically adjusts the pump according to the needs of the system for optimal comfort and lower energy consumption, as well as simple commissioning. ALPHA2 32-80 180 High efficiency fixed rotor circulator, designed for the circulation of liquids in heating systems. With a world-class energy efficiency index (EEI) well below the ErP benchmark, it guarantees significant energy savings. Features AUTOADAPT which provides the highest levels of comfort with the lowest possible energy consumption and makes commissioning easy and safe Night function that saves energy The manual summer mode saves energy during the summer and ensures a safe start into the heating season Intuitive one-button operation makes it easy to select any control mode No external motor protection needed to reduce installation time High torque starting improves starting in difficult conditions Maintenance-free thanks to the encapsulated rotor design and the use of robust components The ALPHA plug makes electrical installation quick and easy Insulating shells are supplied with the pumps to minimize heat loss in heating systems Hydronic balancing through temporary use of ALPHA Reader and the Grundfos GO Balance app allows the installer to perform a quick and easy hydronic balancing When using ALPHA2 with two other components, ALPHA Reader and the Grundfos GO Balance app, it allows installers to perform quick and easy hydronic balancing, without compromising reliability, efficiency and ease of installation. The AUTOADAPT function continuously adapts the pump performance to the actual heat demand, i.e. the size of the system and the change in heat demand over the year. The function will find the setting that provides optimal comfort with minimum energy consumption. It contributes to quick, safe and easy commissioning. In addition, the pump also has three control modes, each with three settings proportional pressure control constant pressure control constant curve mode The display shows actual energy consumption in Watts or actual flow in m3 / h, as well as alarms and warnings. The LEDs indicate the actual operating status. The night setback function, when enabled, automatically reduces the motor speed to save energy. The changeover depends on a change in the flow pipe temperature. Manual summer mode; once enabled, the pump will automatically start frequently at low speed to avoid blocking of the rotor. At the same time, it saves energy. The pump is of the encapsulated rotor type, which means that the pump and motor form an integral unit. The bearings are lubricated by the pumped liquid ensuring maintenance-free operation. The pump is equipped with dry-running protection. The pump has a ceramic shaft and radial bearings, carbon thrust bearing, stainless steel rotor, bearing plate and rotor liner, composite impeller, which contribute to a long service life. The pump automatically bleeds through the system, which contributes to easy commissioning. The compact design featuring the pump head with integrated control box and control panel fits the most common installations. The pump housing is made of cast iron and electro coated to improve corrosion resistance. The motor is a compact permanent magnet / stator synchronous motor featuring high efficiency. The pump speed is controlled by an integrated frequency converter built into the control box.
