Grundfos Circulator ALPHA2 32-60 N 180 Cod.99411448

ALPHA2 32-60 N 180

Product code 99411448

Grundfos ALPHA2 high-efficiency circulators are designed for the circulation of liquids in heating systems. The stainless steel variant of ALPHA2 is suitable for e.g. domestic hot water systems. With an Energy Efficiency Index (EEI) well below the ErP benchmark, it guarantees significant energy savings.

The AUTOADAPT function continuously adapts the pump performance to the actual heat demand, i.e. the size of the system and the changes in heat demand during the year. The AUTOADAPT function finds the setting that provides optimum comfort with minimum energy consumption and makes commissioning quick, safe and simple. ALPHA2 also offers proportional pressure, constant pressure and constant curve control modes.

With the automatic night setback function, the pump switches automatically from normal to night setback. Switching depends on the flow temperature controlled by the heater. In manual summer mode, the pump does not run but starts automatically at low speed to avoid rotor blockage, sticking valves and non-return valves.

Control modes and functions are selected using the buttons on the display. The LEDs indicate the operating status, the actual energy consumption in watts or the actual flow rate in m³/h as well as warnings and alarms.

Furthermore, ALPHA2 is compatible with the ALPHA Reader and the Grundfos GO Balance app, allowing installers to easily hydronic balance radiator and underfloor heating systems.

The design and selected materials of the pump contribute to the long service life. The pump is self-ventilating throughout the system, which contributes to easy commissioning. The compact design, featuring a pump head with an integrated control box, fits into the most common installations. Pump and motor form an integral unit without mechanical seal. The bearings are lubricated by the pumped liquid. These construction features ensure maintenance-free operation.

The active dry-running protection function protects the pump from running dry during startup and normal operation. In the event of a locked rotor, the pump will continuously try to restart with the maximum possible torque.

The cast iron pump housings are electrically coated to improve corrosion resistance. The motor is a compact stator/permanent magnet synchronous motor with high efficiency. The speed of the pump is controlled by an integrated frequency converter built into the control box.

Insulating shells are supplied with pumps to minimize heat loss in heating systems.
