Nocchi CPS Frequency Changer
Nocchi CPS energy saving control system keeps constant delivery when pressure variations occur. CPS frequency converter intergrated into the pump which adjusts motor speed so as to constantly provide users with the same pressure, even when demand for water changes. The main applications for CPS offers elevated comfort and benifits are: home pressurisation, irrigation, greenhouses, light industry, fountians and creative water displays.
Operation
The system consists of an electric pump operated by an electronic control system (speed variator) that enables the delivery of constant pressure by reducing or increasing the flow rate based on water demand. In the case of an excessive system pressure decrease, CPS starts the pump and and regulates its speed until the operating pressure is re-establised. The pump's speed depends water demand. If water consumption increases, the control system raises the speed of the pump up to maximum set valve. If water consumption decreases, the speed of the pump is reduced down to its minimum. If there is no further water demand the pump stops.
