This section includes two PowerPoints which Charlie kept on his website. "A Modern Approach to Selecting Capillary Tubes" is a presentation I gave at the HVACR & Mechanical Conference in 2013 while I was Technical Services Manager for Tecumseh Products. I've also included a link to my current capillary tube sizing app.
The other presentation is on the "Sealed Units Parts Co. (Supco) Compressor and Capillary Tube Tester" which Charlie put together. This device was developed by Henry Ehrens of Supco. Very few of these devices made it to the field.
