It isn't necessary for the air temperature to be below the dew point. All that is required is for the equipment to be below the dew point. It is not uncommon for equipment out at night to cool below the air temperature by radiation into the nearly absolute zero emptyness of space. When the equipment cools down below the dew point then frost forms on the equipment.
I've tried making that point, good luck. The equipment need not be "warm" to the touch, just warmer than the dew point.
