MINNEAPOLIS -- (Business Wire)
Tennant Company (NYSE: TNC), a world leader in designing, manufacturing
and marketing solutions that help create a cleaner, safer, healthier
world said today that it will likely appeal a recent German court
decision in Kärcher’s lawsuit regarding advertisements of Tennant
Company’s proprietary ec-H2O™ technology, a chemical-free cleaning
solution based on the established science of electrolysis.
“Although we have not seen the final written decision of the court we
believe it is, respectfully, based on incomplete and inaccurate
information. The two laboratory bench tests performed by the court
appointed advisor had no or too little correlation to cleaning with a
scrubber-dryer using Tennant’s ec-H2O chemical-free technology,” said
Chris Killingstad, President and CEO of Tennant Company.
Tennant Company continues to stand behind its advertisements of the
ec-H2O technology based on extensive internal and external tests and the
experiences of customers who have years of experience cleaning with
ec-H2O, according to Killingstad.
Tennant maintains that the two laboratory bench tests performed by the
court appointed advisor were seriously flawed. The first test had no
applicability to Tennant’s ec-H2O chemical-free technology as the test
is typically used to measure properties in traditional chemical
cleaners. The second bench test--even if properly performed--has little
correlation to cleaning with a scrubber-dryer, regardless of the
cleaning solution, including ec-H2O.
In addition, the soil sample – comprised of 90% fat and 10% insoluble
pigment - could not be cleaned by a scrubber-dryer even if using a
concentrated degreasing agent. “A laboratory test or bench test in
isolation of real-world conditions cannot in and of itself accurately
reflect the variability present in a customer’s real-world environment,”
Killingstad said.
Killingstad continued, “Tennant ec-H2O customers include many of the
world’s largest and most successful professional cleaning and facility
service providers. Real world operation remains the test that truly
matters and our customers are the true judges of performance.”
Tennant Company introduced its proprietary ec-H2O technology in 2008.
ec-H2O is based on the established science of electrolysis. The U.S.
Patent office has issued more than 800 patents for water electrolysis,
several of which belong to Tennant Company. With scientific testing done
by five laboratories on two continents, ec-H2O has been shown to clean
better than tap water and as well as a general purpose cleaner in many
applications. ec-H2O customers include many of the world’s largest and
most successful professional cleaning and facility service providers. As
of the end of 2012, Tennant had more than 3,500 ec-H2O customers across
the globe, 40,000 ec-H2O scrubbers in the marketplace and $444 million
(USD) cumulative ec-H2O sales. For more information, please go to www.ec-h2ofacts.com.
