Internal Volume

I have a nh3 coil that I am trying to find the Internal Volume on. I have the model# VF4H/3012E and the serial# 347/1 and the make is Lewis Industrial Products made out of Richmond B.C. Canada but they have since gone out of bushiness. Anyone have any information on maybe where to look?

The company that made those coils was Lewis/Cimco. They are now currently known as Cimco Refrigeration. They have offices all across North America. Contact the head office in Toronto and ask to speak to an engineer. They will have the information you require.
