How do walk in coolers that have most of their structure sticking outside, keep from getting too cold in the winter time in a cold climate? If I am thinking correctly, this can't be done without supplemental heaters, can it?
My boss has apparently sold a new cooler to someone that will have most of it sticking outside. The other guys from my shop just got done putting the box together and I am supposed to go out there in a couple of days to pipe it up and make it work. I haven't seen it yet. I asked my boss how we are supposed to keep the stuff inside from freezing when it gets cold in the winter and his response was "that's what the insulation is for". I'm not quite sure, so I thought I'd run it by you guys.
