6.1 Description of the product
The ENERGY SAVING are a range of innovative wet rotor circulators with an integrated
frequency converter (INVERTER).
ENERGY SAVING circulators combine an advanced hydraulic system, a high efficiency motor,
an intuitive electronic control and an operating software that allow to perfectly adapt to the
various operating conditions and the actual needs of the system.
The motor with electronic control module is mounted on the pump housing by four screws.
The criteria for differential pressure control depend on the set operating mode. In all operating
modes, the circulator adapts to the different loads of the system.
