Product Description
The Model OH-DPD is an extension to the Model OH nozzles. The Model OH-DPD allows for the installation of Model OH nozzles in areas exposed to freezing temperatures or otherwise hazardous areas, without compromising the connected wet-pipe system.
The Model OH-DPD extension acts as a unit between the dry Model OH nozzle and the wet-pipe system. Once the automatic nozzle actuates, the Model OH-DPD opens for the supply of water from the wet-pipe system to the nozzle.
