I too am an industry professional. In my 19 years in the industry I have worked on everything from custom made aquarium chillers to 100 ton blast freezers and refrigerated warehouses. At one point in my career I was installing custom refrigeration systems for the local Hunter dealer, as well as maintaining and installing refrigeration systems for a couple of charter companies. I have experience with dual voltage systems as well as engine drive systems. I have made custom heat exchangers and holding plates, and even made my own condensers. I have repaired dozens of systems, and converted plenty of them from 12 to 134a.
These days I mainly work on commercial and industrial refrigeration and HVAC systems, but I still do the occasional boat system for fellow club members.
So, I think I am qualified to speak on the subject....
