ALPHA3 is a circulator designed for heating systems and is fully controlled via the Grundfos GO Remote app, which allows for easy hydronic balancing of radiator and underfloor heating systems.
Grundfos variable speed circulator ALPHA3 32-60 180 cod.99371964
ALPHA3 32-60 180
Product code 99371964
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 delivers significant energy savings.
The ALPHA3 has a built-in Bluetooth radio and is fully controlled by a smart device via the Grundfos GO Remote app. Provides step-by-step assistance in configuring, maintaining and commissioning the pump.
The ALPHA3 communicates directly with the Grundfos GO Balance app, which allows installers to perform quick and easy hydronic balancing.
The AUTOADAPT function, integrated into the radiator and underfloor mode, continuously adapts the pump performance to the actual heat demand, i.e. the size of the system and the variation in heat demand during the year. The AUTOADAPT function will find the setting that provides optimal comfort with minimal energy consumption. In this, it also makes commissioning fast, safe and easy.
Characteristics
- Radiator mode with AUTOADAPT the simple choice for two-string radiator heating systems
- Underfloor mode with AUTOADAPT the simple choice for underfloor heating systems
- Combined radiator and floor mode for systems with a combination of heating systems
- In scheduling and summer modes, a real-time clock allows you to select when the pump should run and not save energy
- Simple user interface: the pump is fully managed by the Grundfos GO Remote app
- Log alarms and alerts with assistance via Grundfos Go Remote
- No external motor protection needed to reduce installation time
- High torque starter improves starting in difficult conditions
- Protection against dry running during startup and normal operation
- 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
Furthermore, the pump also has three control modes with incremental set point adjustment that allows you to adjust the pump setting to a certain operating point:
- proportional pressure control
- constant pressure control
- constant curve mode
The display shows the actual energy consumption in Watts or the actual flow in m3/h. The LEDs indicate the actual operating status.
The design of the pump and the materials chosen contribute to its long life. The pump automatically vents through the system, which contributes to easy commissioning. The compact design, featuring a pump head with an integrated control box, adapts to the most common installations. The pump and motor form an integral unit without a mechanical seal. The bearings are lubricated by the pumped liquid. These construction features guarantee maintenance-free operation.
The pump body is made of cast iron. The pump housing and head are electrically coated to improve corrosion resistance.
The motor is a permanent magnet synchronous motor characterized by high efficiency. The speed of the pump is controlled by an integrated frequency converter built into the control box.
The benchmark for the most efficient circulators is EEI ≤ 0.20.
