Fire Suppression for Heavy Equipment

Heavy Equipment Fire Suppression Systems

Protect Uptime. Protect Operators. Protect Your Bottom Line.

Heavy plant machinery operates under constant stress- high temperatures, flammable fluids, and harsh environments create a persistent and unavoidable fire risk.

The question is not if a fire will occur, but when- and how prepared you are when it does.

Ardent delivers market-leading heavy equipment fire suppression systems, integrated with intelligent telematics, to reduce risk, minimise downtime, and protect critical assets across your operation.

The True Cost of a Machine Fire

A fire event goes far beyond equipment damage. It impacts every part of your business:

• Immediate loss or severe damage to high-value machinery
• Operational downtime and missed production targets
• Disruption across the supply chain
• Risk to operator safety and site personnel
• Regulatory exposure and compliance failures
• Long-term reputational impact

For many operators, a single incident can halt operations entirely.

Engineered for High-Risk Environments

Heavy plant operates in conditions where fire risk is built in:

• Diesel, hydraulic oil, and grease under pressure
• High heat from engines, turbochargers, and exhaust systems
• Dust, debris, and combustible material accumulation
• Continuous operation with limited cooling cycles

Without a dedicated, correctly specified suppression system, these risks escalate rapidly.

The Ardent Approach: Suppression is Only the Start

Many systems in the market react to fire. We work to put the right systems in place to help prevent it, control it, and give you visibility across your fleet.

Rapid Detection and Suppression

Ardent systems are engineered to detect fire at the earliest stage and deploy your chosen agent/s automatically, protecting the machine before fire spreads to critical components.

Application-Specific Design

Every system is specified based on the specific machine type, duty cycle, and operating environment. This ensures effective coverage where fires actually start- not a generic, one-size-fits-all installation.

Installation and Compliance

Ardent systems are installed to meet stringent safety and regulatory standards, supporting compliance across sectors including construction, waste, and heavy industry.

Why Operators Choose Ardent

• Proven performance in demanding, high-risk environments
• Integrated telematics not available with traditional systems
• Application-led engineering, not off-the-shelf solutions
• Strong focus on doing the right thing to ensure uptime, not just compliance

Ardent is not a component supplier, we are a risk reduction partner.

End-to-end heavy equipment fire suppression servicing

As specialists in heavy mobile plant fire suppression systems, we have more than 30 years of proven experience in helping businesses to protect their people and equipment against the risk of fire. 

Coupled with the highest installation standards and fleet of fully trained and highly experienced field engineers, our reliable heavy equipment fire suppression systems are proven to protect operators and vehicles while increasing machine availability and minimising downtime.

After carrying out a thorough fire hazard analysis, our teams specify and design systems tailored to each machine type, characteristics and operating environment - from forklift trucks to 1,000 tonne excavators. Our field engineers install and service these systems to the highest standards, with a level of care and attention to detail to every vehicle that makes us different.

Our large mobile plant fire suppression systems are recognised and approved by most of the UK's major insurance providers, which can help businesses lower insurance premiums.

How our heavy mobile plant fire suppression systems work

1. Detects high temperatures, fast

Our heavy equipment fire suppression systems use a Linear Heat Detection (LHD) cable routed around the identified fire hazards to rapidly detect a fire or high temperature condition. As the LHD cable does not require pressure to operate, it does not suffer from false discharges which can arise due to loss of pressure in pneumatic systems, making the electronic systems a safer and more reliable option for mobile plant.

2. Activates the system

Once the LHD cable detects a fire, it sends a message to the Ardent Control Module to initiate the discharge of the suppression agent within a matter of seconds. A time delay can be set up if required, and the operator can also manually delay the discharge so they’re always in control of the machine.

3. Distributes the agent

Distribution nozzles are critically located to target all identified fire hazard areas in the machine, both inside and outside the engine compartment. A network of distribution hoses connects the tanks storing the suppression agent to the nozzles. On system activation, the suppression agent travels through the distribution network and discharges through the nozzles for effective heavy equipment fire suppression.
