Fire Suppression

As the premier provider of fire sprinkler systems in the region, Oliver is able to outfit a solution for any client. Whether it’s new construction, retro-fits or modifications/additions, our expertise lies in knowing the codes, costs and customer’s needs.

WETSprinkler sprinkling

Ideal for factories, warehouses, office buildings, retail stores, and residences, wet systems are the most common types of fire sprinkler systems. Heat from a fire activates the sprinkler head, causing it to discharge water to the heat source.

DRY

Dry sprinkler systems use automatic sprinkler heads that are connected to a piping system containing compressed air or nitrogen instead of water; typically, this type of system is used in situations like unheated storage areas, coolers, loading docks.

DELUGE

Although similar to pre-action systems, when a deluge valve releases water into the system, all sprinkler heads in the system discharge. The sprinkler heads or nozzles used in a deluge system do not use the “fusible element.”

FIRE PUMPS

Oliver’s engineers perform hydraulic calculations using the parameters for the water source and the project to determine if a pump is necessary—which is common in most high rise buildings due to their elevation.

BACKFLOW PREVENTERS

Backflow preventers are used to protect water supplies from contamination that can occur from the reverse flow of water in a piping system.

FIRE HYDRANTS & SERVICE MAINS

On call at all times, our seasoned team of excavators and sprinkler fitters are experienced in installing cement-lined ductile iron (CLDI) and underground PVC pipe and fittings.

SPECIAL HAZARDS

When traditional water-based systems are not viable, Oliver is able to provide solutions such as clean agent systems, low-and-high expansion foam systems, foam-water sprinkler and foam-water spray systems, water mist systems, and carbon dioxide systems.


We service and install systems in Philadelphia, Eastern Pennsylvania, New Jersey and Delaware.
