VSD installation goes swimmingly!
05 August 2021
INSTALLING A variable speed drive (VSD) to the creature habitats’ water aeration system at SEA LIFE Weymouth has allowed the resident sea animals to enjoy a quieter, cleaner and greener environment. The centre will also benefit from lower operating costs and a reduction in energy usage.
The ABB drive was one of two previously deployed on a sea pump application. It was subsequently determined that only one drive was needed, freeing up the second to be used elsewhere. With the help of ABB Value Provider, IDS, the park identified an aeration system's blower used to oxygenate water within the habitats housing the attraction's thousands of aquatic residents, as a candidate for repurposing the VSD.
Following the retrofit, the VSD enabled a 10% reduction of the blower's motor speed, resulting in an energy saving of £839 per year. By finely controlling the valves on the air lines running to each tank, the park's staff can adjust the pressure depending on a display’s occupants. The blower now runs quieter than before, helping to create a more pleasant environment for guests viewing the animals.
