The amount of moisture in the air of your shop depends on the dewpoint, see http://www.protimeter-usa.com/Support/supdpair.htm , and http://veggie.org/run/humidity.shtml Your metal is colder? Sounds like an ideal condenser. The most economical method, assuming your shop is enclosed, would be to use a passive (chemical) method of keeping the air dry. Of course, if the shop is open, no amount of dehumidification will work. Depending upon the type of machinery and its prime function it could also help to warm the metal, but I suspect that would interfere with whatever function it is that causes the metal to be colder in the first place. If it doesn’t bother the piece of equipment, it may be simpler to just allow for drainage of the condensate. I am certain there is a formula that exists to describe the relationship between the metal temperature, the air temperature, and the rate of condensation; but, the ones I know are used in advanced heat transfer calculations of drop-wise and film-wise condensation. I am not aware of any simpler tables or formulae for the relationship between the temperatures of the metal and air, and the rate of condensation.
