High Power Drives for Vineyard

High Power VLT® AQUA Drives supply the vertical turbine pumps for two main water supply wells at Seven Hills Vineyards in Milton Freewater, Oregon.The two main water supply wells consist of one 250 kW vertical turbine pump and one 630 kW vertical turbine pump. The 250 kW pump can deliver water to the east and middle ponds, while the 630 kW pump can deliver water to all three ponds. Both pumps were supplied with VLT® Aqua Drives.

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.
