The Electroil’s inverters range includes a wide types of products designed to control the feedback pressure of centrifugal pumps in systems in which it’s important to keep the constant pressure control and at the same time contain the operating costs and ensure a longer mechanical and electrical longevity of all the components of the
The working of an electrical motor will be optimized thanks to the frequency converter and to a pressure transducer, setting the number of revolutions in a proportional way to the liquid volume taken from the water supply or from the storage tank and at the same time reduces the transient current during start phase. In addition the current absorption during running conditions will be reduced as well as the water hammering will be attenuated in virtue of the progressiveness with which comes to stopping when the desired reference pressure is reached.
Therefore, the pumps driven by an inverter also ensure a comfortable silentness giving a benefifi t to the fifi nal user.
The Electroil’s inverters are devices of easy and simple application since all are equipped with a special selfinstalling software that through the supply motor cable gets and memorize in an automatic way the pumps features, getting information about the electrical quantities from the motor in every position of the hydraulic curve and through the pressure transducer gets all the information about the pressure value, in order to reproduce, on the internal memory, point by point, the exact working curve of the motor pump.
Thanks to the self-installation procedure (to be done only at the fifi rst starting-up) are detected all the electrical and hydraulic data necessary for the pump functioning in all possible working conditions, to assure a precise stopping because of minimum flow at all the pressures up to the maximum pump pressure, adjustable without modifying any parameters from the menu but simply by pressing the + and – buttons during the working.
This allows an efficient protection against dry working as well as current and voltage protection concerning the electrical part of power of the inverter and motor.
