ABB Drives Reduce Swimming Pool Energy Bills
ABB drives have helped a UK holiday park operator save GBP77,000 a year on energy bills for its swimming pools. Bourne Leisure, which owns brands such as Haven, Butlins and Warner Leisure hotels, has swimming pools at a number of its properties. ABB Drives Alliance partner APDS was asked to investigate the energy-saving potential for the swimming pools and a trial was conducted on two of the three filtration pumps at Bourne Leisure's Devon Cliffs site. The pump was monitored for a period before a variable speed drive (VSD) was installed. Monitoring with a temporary VSD fitted demonstrated that considerable energy savings could be made. The direct-on-line pumps were working at 50Hz drawing an average of 30A. When the drive was introduced, this figure was reduced to 23A during the day and 15A at night, with no effect on water quality. APDS and ABB recommended fitting VSDs to the pumps feeding the pool filters. The pump filters operate by trapping dirt and debris in the sand filte...
