    I told this story here before, but we once installed a new walk-in cooler at a BBQ joint. We had a few call backs because the cooler temperature was running too cold. First guy checked it out,...

    Could you could set it up so that the condensate squirts onto the hot rocks every once in a while? I think we might be onto something here. :grin2:

    Yeah, and air conditioner evaps are around 30. Doesn't seem like that big of a difference to me.
