VSDs were installed on 3 main pool pumps and 2 learner pool pumps by Gibbons Engineering. The VSDs came with a 2 year on-site warranty and the project cost £15k. Due to pool design and water at deck level, the installation initially had an impact on the levels of the pool and balance tank. It took a couple of adjustments to optimise the setup but have managed to reduce the pool pump speeds to 40hz day and night (a 20% reduction in speed).
