APDS Saves BMW Thousands by Implementing a Motor Management Policy The Problem An automotive factory ran a high tech spray booth with staff and product passing through on a continuous basis. The spray heads had paint pumped to them regardless of whether it was required which wasted energy when no paint was called for. The end goal was to be able to keep the pressure and production process consistent, whilst reducing energy costs. The solution needed to be efficient and practical. APDS's Solution APDS installed ABB inverters on the supply and exhaust fan monitor the pressure and using PID controllers they maintain a fixed air pressure according to atmospheric and site conditions. The spray pumps ramp up to speed when a paint is called for, saving energy without allowing the production to su
