Tennant Company and its dedicated
chemical-free technology
development arm, ORBIO
Technologies Group, have announced
the results of an independent thirdparty
study by Elliott Affiliates, a
leading innovator in janitorial
performance evaluation, on the
effectiveness of Tennant’s ec-H2O
technology. ec-H2O converts plain
tap water into a powerful cleaning
agent without any added chemicals.

Study results show that the
technology outperformed the
scrubber dryer using traditional
chemicals by reducing the presence of
ATP by an average of 90.1% versus
84.2%, and reducing the presence of
aerobic bacteria by an average of
95.1% versus 89.7%.
