Danfoss drives keep Espoo water flowing
|
|
|
|
Espoo is Finland’s second largest city, with over 200,000 inhabitants, and relies largely on Danfoss drives for its water supply. Espoo Water has 140 Danfoss drives, including VLT®5000, VLT®6000 and VLT®8000 AQUA models, located in three potable water plants, one waste-water plant and numerous booster stations.

Danfoss VLT® 8000 improves reliability at power station
|
|
|
Cockenzie, a 1200 MW coal-fired power station, employs slurry pumps to convey the coal ash and fly ash. The hydraulic drive units and gearboxes were a problem due to high maintenance cost.
The easiest answer, frequency converter driven motor, directly coupled to the slurry pump.
The system runs for up to 16 hours per day, also with a 38% reduction in energy costs.

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.

VLT® Aqua Drive reduces energy consumption to more than 50%
|
|
|
When the engineers of Laguna Water District were designing the control system of new pumping stations, they decided to use VLT® drives.
After this first initial installation and after the savings in energy cost was confirmed, three more Danfoss VLT 8000 were installed: at the Lamot II Pump Station, Maahas Pump Station and most recently, at the VEGA Pump Station.

VLT® drives 20 irrigators and supplies irrigation water for 100 farms
|
|
|
|
Danfoss secured this order, which includes four 200 kW VLT® 8000 Aqua drives for regulating the pressure and three VLT® Softstarters of 220 kW for the pumps in cascade. The main reason for this was the confidence Danfoss has gained over the years with the company OUVRARD, especially because of the service proximity (before and after sale) and the quality of the drives.
