ABB Drives Cuts Hospital Heating Costs The Problem The heating system in a Welsh Hospital was not working efficiently. The Health Authority was looking to save money on the running costs of the hospital. APDS's Solution The APDS team identified pumps which would benefit from variable speed drive control and estimated the potential savings. APDS offered to install the equipment for a trial period to demonstrate the savings and control offered by the proposed solution. The trial showed that each pump fitted with the APDS recommended equipment could save £4500 per year The Full Story The variable speed drives enabled the APDS engineers to slow the flow, and then set a constant speed. Outside working hours the speed (and consumption) was reduced further to increase energy savings without co
