Tennant Co. (TNC) said Monday 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 noted that it 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.
Tennant maintained 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.
