Fixed fire suppression systems

Fixed fire suppression systems for static equipment

Fixed fire suppression systems provide reliable, cost-effective fire protection for static equipment such as electrical panels, transformer cabinets and enclosed control systems. While fixed equipment is not exposed to the same harsh operating conditions as mobile plant, fire risks remain, particularly in small electrical enclosures where overheating, electrical faults or component failure can quickly lead to ignition.

For compact, well-sealed spaces, a pneumatic fixed fire suppression system offers a highly effective and low-maintenance solution. These systems are designed to detect and suppress fires at the source, helping to protect essential equipment, reduce downtime and minimise the risk of fire spreading to surrounding assets.

Our fixed fire suppression systems are ideal for small-volume applications where targeted protection is required. When activated, the system can rapidly flood the protected area, typically covering a volume within approximately a 0.5-metre radius from the tubing burst point. This makes it particularly suitable for protecting small voids, electrical cabinets and other enclosed static equipment.

With a simple design, reliable performance and minimal servicing requirements, our fixed fire suppression systems for static equipment provide practical, fit-for-purpose fire protection where space, cost and efficiency are key considerations.

Why install a fixed fire suppression system?

A fixed fire suppression system provides reliable protection for electrical panels, transformer cabinets and static equipment. By detecting and suppressing fires early, these systems help reduce downtime, production losses and equipment damage, while protecting valuable assets and your premises.

For businesses, fixed fire suppression systems offer a cost-effective, low-maintenance fire protection solution that supports site safety, operational resilience and business continuity.

How our fixed fire suppression systems work

1. High temperatures are detected, fast Ardent pneumatic fixed fire suppression systems operate using pneumatic tubing, which is pressurised with nitrogen and routed around the fire hazards. The pressurised tubing ruptures locally when exposed to the heat generated by a fire, resulting in a loss of pressure and allowing the suppression agent within the tank to be released.

2. Suppression agents are distributed The loss of pressure in the detection tubing initiates agent discharge. With Ardent direct fixed fire suppression systems, the pressurised tubing both for fire detection and agent delivery. The suppression agent is released directly to the point of ignition to provide rapid and effective suppression of the fire in small spaces.

For larger, well-sealed spaces, our pneumatic indirect fixed fire suppression systems are composed of a distribution network of hoses and nozzles. Following a loss of pressure in the detection tubing, the agent is discharged through the distribution network to cover the hazard area. The nozzles are strategically located to offer optimal coverage of the protected area, suppressing fires in seconds to minimise damage.

Choosing suppression agents for a fixed fire protection system

Fixed fire suppression systems cover a variety of hazards, which may require different suppression agents to provide the best protection for each specific fire risk:

• Clean agent. Our clean agent suppresses fires by removing heat to break the chemical reaction chain. This suppression agent leaves no residue, evaporating cleanly and removing the need for post-discharge clean up. Non-corrosive and non-conductive, it’s the ideal solution for the protection of electrical applications such as electrical panels, data centres, and transformer cabinets.
• Dry chemical agent. For applications where the use of a clean suppression agent isn't appropriate, our dry chemical suppression agent can be fitted. This agent offers excellent fire knock-down capabilities and is able to disperse widely and cover even the hardest-to-reach areas in the hazard area.
