Tennant Company in Joint Development with Kaivac Utilizing ec-H2O Technology in No-Touch Cleaning® Systems

CHICAGO--(Business Wire)--
Tennant Company (NYSE: TNC) and Kaivac, Inc., today announced they are in joint
development to incorporate Tennant`s patent-pending ec-H2O (electrically
converted water) technology into spray-and-vac, or No-Touch Cleaning, systems
for restrooms. Since ec-H2O is a technology that transforms water into a
powerful cleaner, the new system will enable customers to sanitize even heavily
soiled restrooms without the use of potentially dangerous chemicals. This
approach is not only safer but also cost-effective.

"This extension of ec-H2O into No-Touch Cleaning is consistent with our vision
to continue to expand this successful technology into its many potential
applications," said Tennant Company President and CEO Chris Killingstad. "Kaivac
is an outstanding partner. Incorporating ec-H2O into their market-leading
systems and equipment builds upon our mission to clean more of our customer`s
environments in more environmentally friendly ways."

"Tennant is a world leader with a reputation for innovation, and we are excited
to partner with them on this important project. With this announcement, we`re
working together to expand the reach of this innovative technology while making
restroom cleaning more effective, productive, safer and environmentally
friendly. Everybody wins; especially the customer," said Bob Robinson, founder
and CEO of Kaivac, Inc.

A Component of Rapid Restroom Sanitizing Program

Eliminating the need for chemical injection makes ec-H2O technology a key
component of Kaivac`s patent-pending Rapid Restroom Sanitizing program, which
not only accelerates but also greatly simplifies machine operation and training.
In fact, time studies show that the already fast No-Touch Cleaning times can now
be reduced by an additional 40-50 percent while delivering outstanding cleaning
results.

"We`ve done the science and we`re convinced that ec-H2O technology will enable
excellent results in rapid restroom sanitizing mode. The productivity gains
coupled with significant chemical savings result in a compelling ROI," added
Robinson.
