Better Performance Saves Money and Energy

VLT® drives replace on-off operation – with the associated wear and tear and high energy consumption – with a smoother and more precise electronic speed control, allowing plant optimisation and energy saving within HVAC, water and wastewater and automation applications.

Frequency Converters Danfoss Drives frequency converters range from 0.18 kW to 1.2 MW, comes in all enclosure classes and covers the full low voltage range up to 690 V.

VLT® Low Harmonic Drive

The new Danfoss Low Harmonic drives continuously regulate the network and load conditions without affecting the connected motor

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.
