Dry Pipe Fire Sprinkler Systems

All of our automatic fire suppression systems are engineered to meet the standards of NFPA 13 and other loss prevention councils, and they comply with the requirements of governmental codes, ordinances and standards where applicable.

Dry pipe fire suppression systems are installed in buildings where the temperature is cold and the water in a wet pipe system could freeze, thus making a system useless. These systems are mostly found in unheated buildings like parking garages, warehouse storage facilities, and refrigerated coolers.

Here in our warmer Texas climate, dry pipe systems are far less prevalent than wet pipe equipment.

With dry pipe systems, there is no water present in any of the system’s piping until the system is triggered to operate. When activated, the piping is filled with air below the water supply pressure, and water is then routed to the outlets with a higher level of pressure compared to wet pipe systems. Although the components of dry pipe sprinkler systems are relatively simple, these systems can be relatively challenging to design, install, test and maintain properly. Dry systems are intended to be installed within areas that are subject to freezing temperatures and are therefore subject to much harsher environmental conditions than the typical wet pipe sprinkler system. The dry valve, trim, system piping, fittings and sprinklers have a tough existence when compared to other sprinkler systems. Additionally, some of the installation and acceptance test requirements of NFPA 13 can increase the complexity of these systems. One of the challenging requirements of the standard is the 60-second water delivery requirement to inspection test connection.

On a lighter note in considering systems, we have heard comments from building owners who say they prefer dry pipe systems because they convey a “green” appearance. This being that because water is supplied only on demand, the dry pipe systems are viewed as being more environmentally sensitive with water conservation.
