Design & Installation

Wet pipe systems keep water permanently charged in the pipework, allowing for immediate discharge when a sprinkler head is activated by heat. This makes them the fastest-responding system available and the preferred choice for most standard-risk buildings.

Suitable for offices, retail units, residential blocks and mixed-use developments, wet pipe systems are straightforward to install and maintain, offering long-term reliability with minimal servicing requirements.

Dry pipe systems use pressurised air or nitrogen within the pipework instead of water. When a sprinkler head activates, the air pressure drops, opening a valve that floods the system and delivers water to the point of fire.

These systems are commonly specified for unheated warehouses, loading bays, car parks and cold storage facilities where freezing conditions would compromise a standard wet pipe installation.

Unlike standard sprinkler systems, deluge systems use open sprinkler heads connected to a valve that releases water simultaneously across the entire protected area. This delivers rapid, high-volume suppression where fire can spread quickly.

Typically installed in power stations, chemical storage facilities, aircraft hangars and transformer rooms, deluge systems are engineered for environments where the consequences of fire are severe and immediate response is critical.

Pre-action systems require two independent triggers before water is released - typically a fire detection signal and the activation of a sprinkler head. This dual-action approach virtually eliminates the risk of accidental water damage.

These systems are widely used in data centres, server rooms, museums, archives and telecommunications facilities where unintended water discharge could cause significant damage to sensitive equipment or irreplaceable assets.

Gas suppression systems extinguish fire by rapidly reducing oxygen levels or interrupting the chemical reaction of combustion, without leaving residue or causing secondary damage. Common agents include FM-200, Novec 1230 and inert gas blends.

Ideal for server rooms, control rooms, switchgear enclosures and archive storage, these systems provide fast, clean suppression that protects both the environment and the critical assets within it.

Water mist systems discharge fine water droplets at high pressure, creating a mist that cools the fire, displaces oxygen and blocks radiant heat. The reduced water volume means less structural water damage and faster recovery after discharge.

These systems are well suited to heritage buildings, hotels, residential towers and marine environments where minimising water damage is as important as effective fire suppression.

Foam systems work by forming a blanket over the surface of burning liquids, cutting off the oxygen supply and suppressing flammable vapours. They are available in low, medium and high expansion configurations depending on the hazard profile.

Commonly installed in fuel storage depots, refineries, aircraft hangars and loading facilities, foam systems are a proven solution for Class B fire risks where water alone would be ineffective.

Wet risers are vertical mains that remain permanently charged with water, providing fire and rescue services with an immediate high-pressure water supply at every floor of a building. They are a requirement in buildings over 50 metres in height.

We design and install wet riser systems in accordance with BS 9990, coordinating with pumps, tanks and inlet connections to ensure reliable performance when it matters most.

Dry risers consist of empty vertical pipework with inlet connections at ground level and outlet valves on each floor. During an emergency, fire services connect their pumping appliance to charge the system with water for firefighting operations.

Required in buildings over 18 metres in height, dry risers are designed and installed to BS 9990 and require regular testing and maintenance to ensure they remain operational and compliant.
