Fire Suppression

Dry sprinkler systems use automatic sprinkler heads that are connected to a piping system containing compressed air or nitrogen instead of water. Why a sprinkler head is fused, it will first unleash the air/nitrogen in the system followed by water directly to heat source.

You will typically find this type of system used in situations like:

• Unheated storage areas
• Coolers
• Loading docks

Additional Information on Dry Systems:

Deluge Systems are similar to pre-action systems in that the fire sprinkler piping is not primed with water and fire detectors are used to first detect a heat source. After detecting a heat source, the deluge valve releases water into the system. All of the sprinkler heads attached to that fire sprinkler system will discharge water. This is because the sprinklers are “open type” and do not use a “fusible element”.

These applications can be found in:

• Transformers
• Cooling tanks
• Operating equipment
• Generators

Fire Pumps are required in buildings where supplied water pressure does not meet the system demand.  They are a specialized piece of equipment that will increase the incoming water pressure.  Pumps are typically Electric Driven or Diesel powered models.

5 Types of Fire Pumps:

• Horizontal Splitcase
• Vertical In-Line
• Booster Pump
• End Suction Pump
• Jockey Pump

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

Two Most Popular Types of Backflows:

• Double Check Valve Assemble (DCV)
• Reduced Pressure Zone Assembly (RPZ)

Additional Information on Backflows

Fire hydrants and water service mains provide critical access to water for firefighters, enabling rapid extinguishment of fires, safeguarding lives and protecting property. Their reliability ensures essential support for emergency response systems, enhancing community safety. Our emergency team is on-call 24/7. Our seasoned team of excavators and sprinkler fitters are experienced in installing cement-lined ductile iron (CLDI), underground PVC pipe and fittings and are pros in hydrant installation, repair and replacement.
