GREEN DRIVE intervention in the services sector

Telecommunications and Internet company in central Italy, equipped with a data processing centre and a large server farm, with a high demand for cooling energy. The cold-water distribution system is implemented through poorly efficient pumping systems which fall below current standards. The system works in a continuous cycle throughout the year.

Situation before intervention
There were 8 pumps working at set points with throttling and recirculation valves. The energy expenditure for pump operation is €150,000 per year.

The proposed intervention and post-intervention situation
Whitenergy carried out a detailed analysis on each machine, through on-site collection of prevalence, flow rate and electricity consumption data. The solution identified comprises replacing the existing pumps with new pumps, with reduced power compared to the previous ones. The new pumps are equipped with an IE4 electric motor and inverter.
The results of the intervention are:

- savings on electricity for the new pumps, corresponding to €90,000 per year
- improved system management, through an automatic audit and performance monitoring system.

The investment was made in full by Whitenergy. The customer benefits from shared annual savings and is no longer required to maintain the pumps, as this service is carried out by Whitenergy.
