- Stern Engineering – McDonald’s High-Traffic Washrooms (August 2024)
McDonald’s worked with Stern Engineering, Ltd. to install their SWAR sanitary cabinets in the busy washrooms of restaurant establishments. Each unit would feature touch-free faucets, automatic soap dispensers, hand dryers, and a thermostatic mixer-all assembled together for a hygienic and efficient experience. Results:
Less dripping and shorter queues
Reduced maintenance time and soap use
Improved user experience through intuitive LED guides
Better cost control and cross-contamination prevention
