Tennant Company Further Expands Rider ec-H2O(TM) Technology Product Portfolio


Tennant 7100 industrial scrubber now offers the pure power of water with
ec-H2O chemical-free cleaning technology

MINNEAPOLIS-October 1, 2009-Tennant Company (NYSE: TNC), a world leader in designing, manufacturing and marketing solutions that help create a cleaner, safer world, today announces that its very successful breakthrough ec-H2O(TM) technology is now available on yet another larger battery-powered rider scrubber-the Tennant 7100 Micro-Rider Scrubber. ec-H2O technology converts plain tap water into a powerful cleaning agent without any added chemicals.

Tennant Company's ec-H2O technology was originally introduced in late 2007 on the Tennant T3, T5 and 5680/5700 and Nobles SpeedScrub walk-behind automatic scrubbers. Throughout 2009, Tennant Company has expanded its ec-H2O product line by extending its patent pending technology to the Tennant T7 Micro-Rider, T15 Mid-Sized Scrubber, 7300 Mid-Sized Battery-Powered Scrubber and 8300 Battery-Powered Scrubber-Sweeper and the Nobles Speed Scrub® Rider. As a result, the ec-H2O technology is now available not only to commercial customers in retail, hospitality, education and healthcare but also to light and heavy industrial customers in manufacturing, warehousing, aviation, and food and beverage.

"Creating a cleaner, safer world means ensuring that as many customers in as many market applications as possible have access to the most socially and fiscally responsible cleaning technology available," said Chris Killingstad, president and CEO of Tennant Company.

The ec-H2O technology, developed by Tennant researchers and engineers and named by R&D Magazine as one of the most technologically significant developments in 2008, helps to meet the ever-growing need for sustainable cleaning. ec-H2O technology delivers proven cleaning results without the negative environmental and health concerns associated with producing, packaging, transporting, using and disposing of traditional cleaning chemicals. The technology begins as water and ends as water, so it can be handled and disposed of easily and safely; it uses 70 percent less water than traditional cleaning methods, which increases scrub time up to three times per tank; it leaves behind no slippery detergent residue on the floor; and it releases no used detergent discharge into water systems. Eliminating the need for chemical additives enhances worker safety and reduces costs for purchasing and disposal of chemicals.
