VLT® drives for 12 leading brands of data storage media

Moser Baer is OEM supplier to all the 12 leading storage media brands in the world. Danfoss presented AHF Solution to the customer and had marathon discussions to convince them to go ahead with a trial on 4Nos.

Moser Baer observed the performance of VLTs & AHFs. Convinced with the much superior harmonic performance of VLTs & AHFs and significant average energy saving of over 30% on each AHU, Moser Baer placed another order on Danfoss for supply of 40 VLTs, AHFs and Flow Sensors.
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.
