Herefishy, one of the reasons that the load is higher are the heated frames and glass that the low temperature cases require.
Just for clarity, Dan. The load is not higher. The case is designed for a higher load at the (originally intended) lower case temperature. In the Med. temp app., the load is lower than the load of the low temp application.

I selected a C.U. rated at 12,400btuh+ @110degF ambient for the 10-door (glass) case.
