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


Hamilton, OH - October 5, 2009 --Kaivac, Inc. and Tennant Company (NYSE: TNC) today announced a joint development to incorporate Tennant's patent-pending ec-H2O (electrically converted water) 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 heavily soiled restrooms without the use of potentially dangerous chemicals. This approach is not only safer but also cost-effective.

"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.

"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 has proven to be an outstanding partner. Incorporating ec-H2O into their market leading systems and equipment builds upon our mission to clean more of our customers' environments in more environmentally friendly ways."

A Component of Rapid Restroom Sanitizing Program

Eliminating the need for chemical injection makes the ec-H2O system 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 the 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.
