Cooling Tower, Boiler AND General Industrial Applications
The WebMaster 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. It 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.
Now the WebMaster-GI brings the same capability to any pH, ORP or Conductivity application. WebMaster-GI offers the flexibility of SCR Mapping (Sensor-Control-Relay), which allows you to select the Sensor (pH, ORP, conductivity or any analytical analog input), the Control method (ON/OFF, Time Proportional, Flow Based or Timer) and assign them to any Relay. With up to 21 user-defined inputs, the WebMaster-GI can be programmed to control and monitor an array of different input combinations. Each sensor input (either direct sensor or 4-20mA input) can be assigned to a powered relay for control. WebMaster-GI has the ability to bring in 8 analog inputs, 9 digital inputs and is equipped with 8 powered relay outputs. Sensor inputs can also be assigned to any one of the four 4-20mA outputs.
WebMaster-GI is ideal in the following applications –
- Water Treatment
- Wastewater Treatment
- Metal Finishing – Pretreatment
- Generic pH, ORP or Conductivity
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.
The WMB series WebMaster can be configured for your specific boiler application. With 4 conductivity inputs, up to 4 boilers may be controlled using either continuous sampling, or intermittent (timed) sampling. In intermittent sampling, the sample is checked with the valve closed, eliminating flashing to ensure that the conductivity reading is correct. Blowdown based upon that sample may be for a set amount of time, or a for a time that varies depending upon how far from the
set point the reading is. Two-stage intermittent sampling is also available, allowing the user to test the boiler less frequently during times of the day when loading is not as high.
Eight relays provide blowdown, plus either chemical feed or alarm capability. 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 steam load, phosphate concentration, etc.
NEMA 4X packaging and UL/CSA/CE approvals ensure that the WebMaster can withstand the toughest industrial environment.
