This week I answer a question about trimming impellers on pumps that have VFD's. After reading a little bit I think I have a good response thanks to Norm Hall over at RL Deppmann. It is a rather short episode so listen and share it. Show notes as per usual can be found over at www.hvac360.com/138 . Enjoy! Hosted on Acast. See acast.com/privacy for more information.
