VLT® drives pay back in 9 months on boiler fans

Following the installation of a VLT® drive on an 11 kW boiler forced draft fan, Dairy Crest has achieved energy savings of over 47,000 kWh per annum,  reduced associated carbon emissions by 5.52 tonnes per year and achieved a payback on the investment in only nine months.

“In addition to saving us money, the drive has made my life a little easier through reduced maintenance requirements on the boiler." - Craig Pepworth, Dairy Crest.
Danfoss VLT drives energy saving ECplus

Increase Efficiency - Save Energy

A key factor for energy savings in building services is the use of variable speed drives for compressors, pumps and fans.

There are two decisive factors here: the efficiency of the motor (and the machine) and the energy efficiency of the application control.

Because of their high efficiency, the use of motors with permanent-magnet rotors is increasing. Motors with this technolocy are know as 'EC motors' in the HVAC sector.

To allow the users to benefit from the high motor efficiency of EC technology in all areas, Danfoss has refined its tried and tested VVC+ algorithm - as used in the VLT frequency drives - and optimised it for operating PM motors.
