In this issue, we bring you a mix of content you can enjoy when you’re short on time or have a block of time to focus.
In our “Thanks for the Tip” section, video recaps offer practical tips and takeaways on topics such as centrifugal fans, combustion controls, refrigeration system operation, convection dryers, premelter design and cooling tower gearbox tips. Should you want to take a deeper dive after watching any of our 14 videos, you can click to review a related article.
Speaking of reading, technical articles are a great way to gain in-depth insights on a topic. In this issue, we have several articles to help you expand your process cooling and heating knowledge base.
In our cover feature, Andrew Pansulla of Chemours writes about “Designing Your Refrigerant-Management Plan.” He notes that “while regulations such as the Kigali Amendment and the AIM Act have not achieved a total phase-out of HFCs, the need for lower-GWP solutions is evident.” Pansulla offers advice on how to develop a refrigerant-management plan. He also joined me for an interesting podcast interview on the same topic. (Access that via the Listen and Learn page in this issue, or visit process-cooling.com/podcasts any time.)
Also in this issue, Susan Hammock of Alfa Laval Inc. explores how plate heat exchangers can help some companies improve their process efficiency. Benefits such as minimized downtime and less heat transfer loss due to fouling are possible, as she explains in “Efficiency Matters.”
How to use an offset to correct for steady-state errors such as conduction and thermal radiation is the focus of an article by Bill Bergquist of Burns Engineering Inc. Both instrument and installation errors can be present in temperature measurement applications, he notes. An offset is not always the right answer: Simply “using an offset to correct for sensor errors without knowing if the sensor is good can mask a serious problem,” he writes. After an appropriate evaluation of the sensor and installation, however, an offset can help address steady-state errors, and he offers a technique to try.
Boiler cleaning is the focus of an article from the engineering team at Goodway Technologies. Like most process equipment, routine maintenance is the path to a boiler that operates at its highest efficiency. The boiler type as well as the level and type of fouling influence the type of cleaning equipment chosen.
Finally, we have two webinars in October that you can attend online and have your questions answered live. On October 6, Dale Smith of Honeywell will talk about using digital tools to capture process data for better process management, and how digitization can drive sustainability. Register to hear Dale's presentation at process-heating.com/webinars.
On October 19, Chris Pawlak of Alfa Laval Niagara will explain how by switching cooling modes to match the natural temperature cycles of the ambient air, a hybrid air cooler takes advantage of the cooling possibilities offered by nature on any given day. Register at process-cooling.com/webinars.
