Inverter Z guarantees a remarkable energy saving and reduces the noise produced by the fans during the regulation phase.
This is why it is ideal in environments with very limitating noise level restrictions.It is designed for the regulation of three-phase asynchronous motors mounted on heat exchangers.
Suitable when low sound levels are required.
