For a recent upgrade to its La Rosière desalination plant, Jersey Water chose VLT® AQUA Drives from Danfoss
Danfoss states that the principal reasons behind Jersey Water choosing its drives were harmonic performance, high efficiency, compact construction, proven reliability and excellent value for money coupled with the availability of versions for operation from 690V supplies.
Located in the South West corner of the island, the current desalination plant is the second on the La Rosière site and was opened in 1999 as a replacement for an earlier distillation plant which had reached the end of its life. After the new plant had been in service for almost two decades, growing demand for water on the islan led to the decision to undertake a major upgrade. This would increase the plant’s capacity from 6 Ml/day to 10.8 Ml/day, which is sufficient to meet around half of the island’s daily demand for water.
The upgrade involved the installation of a large number of new pumps, almost all of which would need to be controlled by AC variable speed drives. After investigating the available options and going through a competitive tendering process, Jersey Water decided that the Danfoss VLT® AQUA Drives were the most suitable choice on both technical and commercial grounds. Accordingly, the drives were specified for all applications related to the upgrade project.
