GREEN DRIVE intervention in the industrial sector

Chemical plant in northern Italy, operating in the production of “chemicals” used in the aluminium industry. The pump fleet is obsolete and inefficient, given that it operates in a continuous cycle throughout the year.

Situation prior to intervention
There were 6 pumps operating at set points with throttling and recirculation valves. The annual energy expenditure for pump operation was €130,000 per year.

The proposed intervention and post-intervention situation
Following a detailed audit on each machine, Whitenergy took detailed on-site measurements of prevalence, flow rate and electrical consumption. The ideal solution was then identified, consisting of the replacement of existing pumps with new pumps, with reduced power compared to the previous ones. The pumps are equipped with an IE3 electric motor and an inverter.
The results of the operation are:

- savings on electricity to power the new pumps
- improved system management, through an automatic audit and performance monitoring system.

The investment wasmadein full by Whitenergy. The customer benefits fromtotal shared savings of € 60,000 per year and is no longer required to maintain the pumps.
