This job involved PressBoost replacing an existing U/S variable speed control panel on a three pump boosted water unit supplying a hotel, with a new panel fitted with ABB inverters. In conjunction with ABB we have developed a range of variable speed control panels that can be retrofitted to all makes of existing fixed and variable speed booster units, irrespective of the number of pumps. The existing panel was completely U/S, as such, the unit was running fixed speed 100{546ee268ce7713d2b6d4f6ff974fadd45b4c551b6f43a7e80340ad9a7da26c27} of the time, this had been the case for some considerable time and was in urgent need of replacement. It proved cost effective to only replace the panel and change the inverters because the pumps and pipework were in perfect condition. By reinstating the pumps to variable speed again the site will see a considerable energy saving. This will also improve the operation and increase the longevity of the unit, as the previous mode of operation was placing a lot of strain and wear on the pumps. When converting from fixed to variable speed there is a significant energy saving (between 30-50{546ee268ce7713d2b6d4f6ff974fadd45b4c551b6f43a7e80340ad9a7da26c27} annually) which means that the cost of modification can be recovered fairly quickly and future energy savings means that it is extremely cost effective.
