AutomationDirect has added a new line of AC variable frequency (VFD) drives for motor speed control and other industrial control applications.
The WEG CFW300 variable frequency drive is a high-performance VFD for three-phase induction motors. It is ideal for applications on machines or equipment that require precise control with easy setup and operation. The CFW300 features a compact size with contactor-style electrical connections (top in / bottom out). The VFD's performance can be scaled to match the application by selecting WEG vector control (VVW) or scalar control (V/Hz).
The CFW300 includes a built-in keypad and SoftPLC with free WEG Programming Suite (WPS) software for custom tailored control schemes. The integrated WPS tool assists in the creation of automation applications, allowing graphical monitoring, parameter setting and programming in Ladder language (IEC 61131-3).
Built-in I/O capabilities include four configurable (PNP or NPN) digital inputs, one 0.5 A / 250 VAC relay output, and one 0-10 VDC / 4-20 mA analog input. A variety of plug-in option modules for additional I/O and communications protocols can be added to extend capabilities. A remote keypad and flash memory module are also available.
Starting at $138.00, sixteen units are available from 1/4 hp to 5 hp. Single-phase 100-127 VAC, and single or three-phase 200-240 VAC power supply options are available. WEG CFW300 series AC drives are cUL, CE approved and are backed by an 18-month warranty.

Breweries are known for transforming malt, hops, and yeast into beer in gleaming brewing kettles and large fermentation tanks linked by numerous pipes.
Over the centuries, the equipment for mashing, lautering, boiling, and fermenting beer according to carefully guarded recipes has been steadily perfected.
The chiller is the heart of the brewery
One of the most important parts of the brewery, and perhaps the least visible, is the chiller. The fermentation temperature of the beer is crucial, which means that the heat generated by the yeast fermentation must be carefully controlled by the chiller.
If the beer ferments at too high a temperature, the yeast can produce a variety of undesirable aromas that ruin the beer.
According to Justin Thomas, President of G&D Chillers, based in Oregon
"The chiller is the heart of the brewery. Owners invest not only a lot of money in the brewery and brewing equipment, but also a great deal of time in the production of beer. But if the chiller fails, all that goes out the window."
Partnerships to keep pace with growth
Thomas says that growth at G&D Chillers has been exponential over the past 15 years. To continue this rate of success, the company had to look for new ways to meet customer demands for reliable, state-of-the-art chiller options.
For example, G&D Chillers recently teamed up with Siemens and the global distribution and supply chain solutions company WESCO to meet these needs and stay ahead of the competition. "We're still a small manufacturing company, but big enough to produce some technically advanced equipment," says Thomas. "We've always been service-oriented and always stood by our equipment, no matter what the problem. We get the same kind of support and service from Siemens that we give to our own customers."

Convenient Power Infeed and Distribution
The 3RV29 infeed system is based on a basic module complete with a lateral incoming supply unit (three-phase busbar with infeed). Expansion modules (three-phase busbars for system expansion) are available for extending the system.
