	With Shoulder Tap Technology

The Web Master has proven to be the most revolutionary product the Water Treatment market has ever seen. Walchem's Patent-Pending ShoulderTap Server-On-Demand technology provides instant real-time access to the WebMaster controller when you need it without the need to be permanently connected to the Internet.

WebMaster offers the ability to control and monitor cooling tower and boiler systems using a standard web browser from any computer - anywhere in the world. Unlike traditional modem-to-modem communications, ShoulderTap eliminates long distance phone calls, proprietary software and allows simultaneous multi-user access. In addition, the WebMaster delivers a range of new technology capabilities including user-friendly programming, multi-user access and e-mail notifications for datalogs, alarms and system summaries.

The WMT series WebMaster can be configured for your specific cooling tower application. With 4 direct sensor inputs, the WebMaster is capable of monitoring system conductivity, make-up conductivity, pH and ORP. It can also be equipped with eight (8) analog inputs and six (6) digital inputs capable of monitoring tank levels, providing interlocks, feed verification and receiving other plant parameter signals such as corrosion rates, biofilm monitors or phosphate concentrations.

NEMA 4X packaging and UL/CSA/CE approvals ensure that the WebMaster can withstand the toughest industrial environment.

WCT Series

WDT & WCT Cooling Tower Controllers

Walchem offers a variety of on-line controllers for your cooling tower applications. With a choice of two different NEMA 4X models, WDT300/310 (Dual Input Cooling Tower) or WCT300/310 (Single Input Cooling Tower), finding the perfect fit for your cooling tower is simple. The WDT300 Series can control conductivity (bleed and feed) for two independent towers. The WDT310 Series is equipped to control conductivity, pH (or ORP) and programmable dual biocide outputs for a single tower. The WCT300 is a single tower, feed/bleed, conductivity controller and the WCT310 adds a programmable dual biocide output option. All Walchem cooling tower controllers are microprocessor-based with an easy-to-use menu format for programming. UL/CSA/CE certified.

WDT Series

Water Meter Inputs with Flow Totalizer
Optional 4-20 mA output(s)
Conductivity-based biocide prebleeds
Lockout timer after biocide additions
Flow switch manifold assembly (optional)
Four Chemical Feed options:

Feed & bleed simultaneously
Feed after bleed has finished
Feed as a percentage of time elapsed
Feed as a percentage of make-up water

WDB / WBL Boiler Controllers and Condensate Monitors
	Walchem offers four different Boiler Water Controllers and Condensate Monitors. The WBL Series controls conductivity blowdown/chemical feed for one boiler and the WDB Series controls two boilers within 500 feet of each other. Ever worry about those nasty chemicals that you're heating up leaking into the condensate lines and eating up your boiler? Worrying never helped anything, but installation of a condensate monitor will! The WCM Series controller will keep a watchful eye on the conductivity of the condensate and divert the flow away from your boiler if it gets too high. A small price to pay for peace of mind! Our WCM Series control the conductivity of a boiler's condensate and the WDC Series can control the condensate of two boilers (within 500 ft.). All of Walchem's Boiler Water and Condensate Monitors are micro-processor-based with an easy-to-use menu format for programming. UL/SA/CE certified.
