no, dry systems are used for exposure to cold climates. be it out side or in freezers. some places that have a lot invested in computers use whats called a pre-action system, where 2 things have to happen in order to set the valve off (smoke detector, "magic" wire, fusing a head, or they have a "huffer" system connected to it). huffers can "smell" a wire going bad and arm the valve.
dry systems are worse for corrosion. they have to be trip tested once a year then drained, but some water always stays in the pipe and that mixed with the air will rust it faster. anyways now im rambling.
