Ordering Information Electroless Copper/Nickel Controllers WNI41 Dual Input voltage WebMasterONE is the most advanced online cooling tower and boiler controller in the water treatment industry. The flexible multi-I/O platform allows you to control multiple cooling towers, boilers, closed loops, and condensate lines with just one controller. An extensive assortment of integrated communications and data handling features are included that enable water treatment professional to provide more effective water management services to their customers. WCU/WNI400 Series Walchem’s WCU410 Copper Controller and WNI Nickel Controller are optoelectronic on-line analyzers that measure the actual concentration of copper or nickel in solution. They are used in a variety of applications including electroless plating baths and microetch baths (including oxide-replacement types). Metering Pumps The E-Class is the most innovative and comprehensive metering pump product line in the world. Over 50 years of pump experience and a commitment to superior mechanical design has led to development of many industry firsts, including 360 stroke-perminute technology, IP67 waterproof construction, and the world’s highest capacity solenoid metering pumps. DUAL INPUT 0 = None 1 = pH input* VOLTAGE 1 = 120 VAC, prewired 5 = Hardwired, cable glands WIND WebMaster® Industrial Water Controllers Walchem’s WebMaster Industrial (WIND) Controller sets a new standard for Industrial Water Treatment Controllers. WIND has a flexible multi-I/O platform, a wide range of analytical sensor measurement capabilities, and an extensive assortment of integrated communications and data handling features. OUTPUT N = No 4-20 mA data output 2 = Two isolated 4-20 mA outputs (WNI411 only) 4 = Single Isolated 4-20 mA output SENSOR N = No sensor 1 = Flow through sensor 2 = Immersible sensor (WCU only) WebAlert® Remote Monitor 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. USB FEATURES U = Integrated datalogging, event/reset logging, and configuration file import/export *WNI: For easy installation, order sensor option “N” plus a 190921 (120VAC) or 190922 (240VAC) sample system when ordering the pH option. The WCU410 may be switched from electroless copper to microetch via the menu, eliminating the need for a second controller. It reduces the need for manual titration, improves yield, and in microetch applications improves productivity by reducing the frequency of bath change-outs. The WNI410 is available as nickel-only, or with a pH control option which may be added in the field. Two separate pump outputs for nickel and reducer and another for pH are used, each of which is capable of totalizing either pump on-time, volume pumped, or metal turnovers. 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 copper or nickel measurements, and relay status. Download logs from the USB stick to a PC at your convenience. It couldn’t be easier! Summary of Key Benefits Concentration Read in Units Selectable between grams per liter (g/L) or ounces per gallon (oz/gal). Backlit digital display also acts as a bar graph for a continuous “visual summary” of measurement versus set point. 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 Operator Adjustable Concentration set point, alarm set points (high and low), dead band and pump on time are all easily adjustable. An interlock feature allows external devices (such as a flow switch ) to interlock control relays. Simple, Integrated Data Collection Download stored data from the controller to a USB stick. Use the data to simply and easily validate system performance. The data and event logs show copper or nickel values, as well as accumulated chemical feed and relay activation times. Four Separate Control Relays & Outputs (WCU) May be used to add copper, caustic, formaldehyde or chelator/stabilizer chemistries. Each output has a replenishment totalizer which may be set in units of time or volume. Walchem, Iwaki America Inc.
