Walchem’s WebAlert is the first stand alone remote monitoring
device that can web enable your installed equipment without
having to replace or upgrade it.

Designed to be flexible and versatile, the WDIS Series controller is
the ideal solution for disinfection applications in cooling towers, food &
beverage, drinking water, wastewater and swimming pools.
Integrated datalogging is available to validate system performance. A
USB memory stick is all that’s needed to extract data and event logs
that include disinfection sensor measurements and relay status.

Summary of Key Benefits
Versatility for a Broad Range of Applications
Choose from four standard industrial grade sensors in one controller (chlorine/bromine, chlorine dioxide,
ozone, peracetic acid) or configure the controller to use a variety of other disinfection sensors. Relays
can be configured for Hi Alarm, Low Alarm, Out-of-Range Alarm, In-Range Output or Probe Wash, providing
unmatched flexibility.

ABOUT US
Walchem integrates its advanced sensing, instrumentation, fluid
pumping and communications technologies to deliver reliable and
innovative solutions to the global water treatment market.
Our in-house engineering is driven by quality, technology and
innovation. For more information on the entire Walchem
product line, visit: www.walchem.com

Note: For EN61000-4-6 & EN61000-4-3 the
controller met performance criteria B.

Economical and Simple to Use
WDIS controllers are economically priced and do not require any costly reagents. The rugged NEMA 4X
enclosure and panel mounted flow assembly has only two process connections for quick and easy installation.
Built-in Safety Features
Programmable output limit timers prevent run-away chemical addition. Digital Interlock Input may be used
from a flow switch or level input to prevent chemical addition based on a stagnant sample, or control of an
empty batch tank. The alarm relay notifies plant personnel of alarm conditions as soon as they occur.
Simple, Integrated Data Collection
Download stored data from the controller to a USB stick. Use the data to simply
and easily validate system performance, document compliance and reduce liability.
The data and event logs show disinfection levels, as well as accumulated chemical
feed and relay activation times.

*Class A equipment: Equipment suitable for use in
establishments other than domestic, and those
directly connected to a low voltage (100-240 VAC)
power supply network which supplies buildings used
for domestic purposes.

with sensor option “N” then order the appropriate
sensor separately.

Walchem’s WDIS Series controller will reliably and economically
control your water treatment disinfection process. The controller
includes four standard sensor input options (free chlorine/bromine,
chlorine dioxide, ozone, peracetic acid) or can be configured to use
a variety of other types or ranges of Walchem disinfection sensors,
such as hydrogen peroxide or total chlorine.
