Specifically designed for buildings susceptible to freezing, dry pipe sprinkler systems feature automatic and closed-type sprinkler heads connected to pipes filled with pressurized air or nitrogen. The compressed air holds a remote valve, known as a dry pipe valve, in a closed position to prevent water from entering the pipe. When heat activates one or more sprinklers, the compressed air in the pipe is released, and its pressure decreases, opening the dry pipe valve and allowing water to flow through open sprinklers.
Ideal environments for dry pipe fire sprinkler systems include:
At E & E FIRE PROTECTION, we design, install and repair dry pipe fire suppression systems for a variety of companies, including those operating industrial warehouses, retail parking garages, loading docks and commercial freezers. Our E & E FIRE PROTECTION team is also experienced in combining dry and wet pipe fire sprinkler systems in settings where only a few sections lack heat.
