VLT® frequency drives for high quality pet food

The reliability of Danfoss drives plays an important role for Nestlé Purina.
“We have only one production line.” says Maarten Wolde.

Nestlé has used Danfoss Drives for many years. Danfoss drives have a very long service life. The old Danfoss Drives installed many years ago were still going strong. Only because of the need for Profibus communication, Purina was forced to replace these old drives for newer Danfoss models.
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.
