Hand Dryer Case Study (Large office complex) - One Station Square, Cambridge

The challenge

Paper towels were the original hand drying method of choice. The tenants decided that hand dryers would be more cost effective and more eco- friendly. This would also match the eco credentials of the building.

 “The service provided by Intelligent Facility Solutions Ltd, especially Andrew Cameron was excellent, I can't recommend them highly enough. The hand dryers themselves are exactly what we required and have received excellent feedback.”
