Study Confirms Effectiveness of ec-H2O Technology

May 24, 2010

MINNEAPOLIS, Minn., May 24, 2010-Tennant Company and its dedicated chemical-free technology development arm, Orbio Technologies Group, today announce the results of an independent third-party study by Elliott Affiliates, a leading innovator in janitorial performance evaluation, on the effectiveness of Tennant’s ec-H2O technology. ec-H2O technology converts plain tap water into a powerful cleaning agent without any added chemicals. The third-party study confirms that ec-H2O technology performs exceptionally well even in very challenging environments. This study confirms ec-H2O powerfully cleans as well as or better than automated scrubbing technologies using traditional chemicals in four key categories, including cleanliness, hygienic safety, appearance and sustainability.

“Since we introduced the cleaning industry to chemical-free floor cleaning in 2007, we have been overwhelmed by the exceptionally positive feedback we’ve received from customers and industry experts alike,” said Chris Killingstad, president and CEO of Tennant Company. “It is both gratifying and affirming to receive that same kind of positive feedback in the form of a credible third-party study.”

The Elliott Affiliates study was specifically designed to test ec-H2O’s performance under real-world cleaning conditions. For that reason, testing occurred in a Baltimore-based soft drink bottling plant that is operational 24 hours per day, seven days per week. Floor conditions in the plant included sugary syrup residue; petroleum-based stains and residue; and dirt, oil and other outside debris. Five different test areas within the plant with either unfinished concrete or VCT flooring were identified, including the pallet area, a corridor, a loading dock, a bottling area, and a cafeteria, and, over a period of three days, half of each test area was scrubbed with a Tennant traditional automated scrubber and the other half with a Tennant automated scrubber equipped with ec-H2O technology.

The study focused on four key test categories, including cleanliness, hygienic safety, appearance and sustainability. Cleanliness and hygienic safety were measured by testing for the presence of adenosine triphosphate (ATP), which indicates the presence of contamination, such as food residue, allergens and/or bacteria. Appearance was measured by taking before and after photographs. Sustainability was measured by testing and comparing a list of factors related to the social, economic and environmental impacts of the technologies.

Study results show that ec-H2O technology outperformed the automated scrubber using traditional chemicals by reducing the presence of ATP by an average of 90.1 percent versus 84.2 percent and reducing the presence of aerobic bacteria by an average of 95.1 percent versus 89.7 percent. Results also show that ec-H2O performed as well as or better than the traditional automatic scrubber in removing visible soil and improving overall floor appearance. And, based on the sustainability factors outlined and measured, ec-H2O technology provided superior environmental, economic and social benefits over the automated scrubber using traditional chemicals by using 70 percent less water, releasing no used detergent discharge into water systems, eliminating chemical residue, enhancing worker safety, and eliminating the costs for purchasing and disposing of chemicals.

“At Elliott Affiliates, we pride ourselves on conducting independent and thorough evaluations on the performance of janitorial products and technologies,” said Vince Elliott, founder and CEO of Elliott Affiliates, Ltd. “In this particular study, ec-H2O technology was the clear winner in all categories when tested against commonly used automated scrubber technologies using traditional chemicals.”
