Commercial laundry operations are no simple matter. From distinct chemistry dosing to technical programming details, tunnel washers create complex challenges. When one commercial laundry facility was feeling the pain of these challenges, they called Ecolab’s Tunnel Doctors™ for treatment.

The laundry was experiencing high water consumption, diluted chemicals in targeted zones and improper finishing of linens due to inconsistent pH levels, resulting in towels with poor wash quality and rough feel. They desperately needed help improving their results – and their operational efficiency.

We prescribed solutions that dramatically improved quality and efficiency.


With a specialized skill set no one else can offer, our Tunnel Doctors performed a complete plant survey and thorough analysis of all tunnel operations, chemistry and processes. They identified improper settings in the rinse zone, over-dilution of chemistry, leaking valves and excessive temperature settings in the dryer – and then prescribed solutions that decreased water and energy consumption, optimized dosing and pH levels, and vastly improved overall wash quality and feel. With the gains the laundry made in efficiency, they were able to invest in new technologies to grow their business and maximize their profits.

  • By identifying and fixing the inefficiencies, the plant was able to save 303,680 gallons of water a year
  • Overall utility costs were reduced by $45,000 annually
  • Ecolab’s Tunnel Doctors manage more than 70 percent of the tunnel washers in North America
