Mechanical Fixed Fire Suppression

In addition to Wet Sprinkler systems, we can also provide Dry Sprinkler systems. Dry sprinklers differ from wet, instead of having pressurised water ready in the pipes, the pipes are filled with pressurised air or nitrogen. In the event of a fire, once the sprinkler activates, the air pressure drops releasing pressurised water into the system.

Pre-action sprinkler system uses the same system as Dry Sprinkler systems. However, water will not flow into the pipes until the fire detection system operates, after activation. The purpose of this delayed water release is that it will potentially save valuable assets from water damage or accidental discharge.

Deluge systems hold back water through an electrically operated deluge valve. The pipework are filled with water, the sprinkler heads opening when the system is activated. When activated, the water is released from all the heads simultaneously. Camerfield provide Deluge systems with a Foam/Water mix, this is an effective deterrent to control a fast-growing fire.

Tailored specifically by our design team, an installation of pipework and pumps create an effective Fire hose reel system. Ready for the correct provision of instant water to tackle a small localised fire.

Water flow is enabled after the system is manually activated and operated. The pressure loss activates a pump, ensuring that the correct water pressure and flow creates a jet to combat fires.

We provide a variation of tailor-made Foam Sprinkler systems;

Form Water spray systems consists of a foam concentrate and water supply equipped with foam-water spray nozzles.

A foam-water sprinkler system is, connected to the water supply through a control valve, this is usually actuated by the operation of automatic electrical detection equipment, or from pneumatically charged sprinkler head detection line.

Medium and High expansion foams provide a unique agent for transporting water to inaccessible places. This includes total flooding of confined spaces and the volumetric displacement of vapour, heat and smoke. They can also be used to cover flammable liquids or volatile substances.

Dry Riser systems are used to pump water up to the higher floors of a building, usually over 18 metres in height, in accordance with set regulations (BS9990 – 2015). A Dry Riser is kept empty until required for use. The Dry riser will then be charged with water. The Fire service will access and use the designated outlets and landing valves to disperse water over the fire. These valves are provided throughout the building.

When a building is higher than 50 metres above fire service level, Wet Risers are the systems that must be installed. Unlike the Dry Riser, the system is always charged with water, ensuring water is immediately available on all floors.

*Floors no higher than 50 metres above fire service access level and have fire mains installed, may have Wet or Dry Riser systems Installed*

A fire hydrant system is a specifically pressurised water that flows throughout a building, installed to a pre-designed connectivity of valves for fire-fighting purposes. To be able to attack a fire from different angles, the system is installed expansively. Due to their strength, these systems are installed accordingly to fight medium to large fires.

We can also provide external systems that are readily available for quick action and are easy to operate. Compared to the Internal system, External Fire Hydrants are installed around the perimeter of the building.
