Can cold plate refrigeration be changed to cold plate freezer??

[dkratzer1]

Hello,

Can someone help. I purchased a box truck that has cold plate refrigeration..that works great. It holds at about 38 degrees. My problem...the person that I purchased it off of said it would get to freezing. I need to haul frozen foods. I have been reading about the plate system. Can the fluid in the plates be changed, I guess it is salt brine, to make a lower temperature? I noticed that the plates have drains on them to remove the fluid. I can't find anyone in my area that knows anything about these cold plate systems. From what I have been reading the only difference is the solution and the temp at which it freezes. Can someone please Help!

Hi Dkratzer1, it seems to me that you will need significantly more cooling capacity. As the previous owner told you it would get to freeze, that could mean 32f, water will freeze but you need 0 degrees for frozen goods.
