Tennant Auto
Scrubbers
Uses activated-water technology,
called ec-H2O ™, in a line of
their auto scrubbers. This is the
same technology that is used in
the Activeion products.
Due to the contact or
dwell time requirements
that the surface must
remain wet to achieve
sanitization or
disinfection (2–10
minutes), Tennant has
not pursued registration
of ec-H2O because it is
in contact with the
flooring surface for only
2 to 3 seconds
Aspen Research
Corporation in St. Paul,
Minnesota, performed
third-party testing.
The technology has
also been tested by
NSF International for
use in food, beverage,
and drug processing
locations.
ec-H2O is certified by
Underwriter's
Laboratories (UL).
Tennant Company
developed Activeion’s
activated-water
technology (ec-H2O) and
then licensed Activeion
Cleaning Solutions to
develop the hand
sprayers.
Benefits include reduced
chemical and water
usage, and the elimination
of chemical residue on
floors.
Thermal Accelerated
Nano Crystal Sanitation
(TANCS®) Steam Vapor
System
Developed by Advanced
Vapor Technologies,
LLC
Bauer Energy Design,
Inc. holds the patent on
this technology.
The TANCS Steam Vapor
System technology (see Figure
2) works by facilitating the
redistribution of charges
between the water molecules and
dissolved mineral components
naturally found in tap water,
which results, in part, in the
development of nano crystals.
This enhanced water is then
transformed into super-heated,
low-moisture steam.
Creation of the nano crystals
results in a micromechanical
component in addition to a
Includes claims to
effectively kill a broad
range of microorganisms
within 3 to 5 seconds,
reducing surface-
mediated infection risks.
Classified as a
disinfection device with
a 3- to 5-second dwell
time and is effective
against a broad spectrum
of microbes.
Nelson Laboratories,
Inc. of Utah certified
that a 7-second
exposure to TANCS
steam vapor produced a
5- to 7-log reduction in
microbes, which was
consistently achieved
on all microbes tested.
Test steps:
1. Microbes were
grown in liquid
culture or harvested
from stock
Does not use chemicals,
only tap water.
It can penetrate deeply
and quickly into nooks,
crevices, and microscopic
pores in surfaces.
Although it has a dry
(6%) moisture content,
the manufacturer
recommends that to
reduce risk for mold after
use, all surfaces must be
dried and rooms must be
ventilated and not closed
