Understanding the Value of Arc Flash Management and Mitigation for Large Electric Process Heaters
When medium-voltage equipment is used for industrial applications, it carries with it certain risks. Arc flash is an example of a well-known electrical risk that requires certain best practices to be ...
Tackling Thermal System Complexity: The Promise of ATS™
The benefits of precise thermal control also come with an engineering challenge: Keeping the complexity of the system in check while addressing issues of thermal uniformity and system responsiveness. ...
Reducing Heater Fouling in a Bisphenol A (BPA) Application Using HELIMAX™
By using HELIMX™ circulation heaters in its BPA processing, a manufacturer was able to widen its maintenance window by two to three times what it traditionally has been, saving both time and money. Re...
What is Heater Bakeout and Why is it Important?
The process of “baking out” a heater can be a costly and, failure to perform this critical step prior to applying full power to a heater could have catastrophic effects if moisture is present. Watlow ...
Examples of Equipment Refurbishment Opportunities to Control Costs in Semiconductor Fabrication
Many parts critical to front-end semiconductor fabrication (such as electrostatic chucks,wafer pedestals, ceramic heaters and implant wheels) experience wear-and- tear over time. This can cause parts ...
An Essential Guide to Power Controllers
The power controller is a discrete output device that regulates your system with guidance from the temperature controller. There are three common power controllers: electromechanical relays, solid-sta...
Why it is Time to Replace Mercury Relays
Mercury relays have been a primary power switching solution for nearly 90 years. Switching to solid state relays has many advantages to better monitor your systems. A proactive approach to replacing m...
How Watt Density Specifications May Be Holding Back Optimal Electric Heat Exchanger Design
Typical customer specifications for a direct electric heat exchanger (DEHE) in forced convection gas applications aim for efficiency and safety given the technology principles that have been in place ...
For the Best User Experience, the Interface is Everything: Introducing PM PLUS™
According to the best available research, improvements in the user interface in a piece of technology can yield improved efficiency of up to 700%, factoring in ease of use, ease of training and reduct...
Better Predicting Terminal Enclosure Temperature to Improve Heater Reliability
One of the most common failures in electric process heaters used in various industrial applications involves electrical terminations and not the heating elements. Engineers at Watlow® believe designer...
What is a Control Loop and How do I Set it Up?
A temperature control loop is one of the most common examples of a control loop. Control loops work to maintain the temperatures in our homes and offices. They are used for a range of immersion and in...
Meeting Nadcap Requirements with Modern Data Logging Methods
Modern process controllers not only help suppliers in the aerospace industry to comply more easily with Nadcap requirements and speed up audits—they also help guarantee quality. A great example of suc...
