Ansul Vehicle Fire Suppression Systems
Talk to a safety specialist
Off‑road and heavy industrial equipment operate in some of the most demanding environments imaginable. High temperatures, hydraulic fluids, fuel, electrical components, and combustible debris can all combine to create serious fire risks. Ansul vehicle fire suppression systems are designed to detect and suppress fires quickly—helping protect operators, equipment, and operations from costly damage and downtime.
Levitt‑Safety is proud to be Ansul’s first and largest Canadian distributor, and a Triple Diamond Distributor and Service Centre for vehicle fire suppression systems. With decades of experience supporting industries such as mining, forestry, construction, and waste management, we help customers select, install, and maintain fire protection solutions built for real‑world conditions.
Why vehicle fire suppression matters for heavy equipment
Fires on mobile equipment can escalate rapidly. A minor hydraulic leak or electrical fault can quickly turn into a major incident, putting lives, assets, and productivity at risk. A properly designed vehicle fire suppression system:
- Detects fires early
- Automatically activates suppression
- Alerts operators
- Helps reduce equipment damage
- Minimizes downtime and operational disruption
Ansul systems are purpose‑built for heavy equipment operating in extreme heat, cold, vibration, and debris‑filled environments.
A Legacy of Innovation in Vehicle Fire Suppression
In response to the mining industry’s growing fire risks, the first Ansul vehicle fire suppression system was introduced in the 1960s. As equipment increased in size and complexity, Ansul continued to evolve its technology—developing systems that meet modern fire hazards while supporting operational efficiency and environmental responsibility.
Today, the ANSUL® brand includes a comprehensive line of special hazard fire protection products, developed and tested at the ANSUL Fire Technology Center and supported by a global network of trained distributors.

Ansul vehicle fire suppression system options
LT-A-101 Dry Chemical System
The Ansul LT‑A‑101 cartridge‑operated dry chemical system is one of the most widely installed vehicle fire suppression systems on heavy equipment worldwide.
Key features:
- Designed for harsh, hostile environments
- Operates in extreme temperatures from ‑65°F to 210°F (‑54°C to 99°C)
- Corrosion‑resistant components
- Available in 20, 30, 50, 125, and 250 lb agent capacities
- Expellant gas cartridges tested to detect ultra‑low leak rates
The A‑101 system can be installed as a standalone solution or paired with an Ansul LVS system to create a twin‑agent fire suppression system.
LVS™ NF 40 liquid agent system
The Ansul LVS NF‑40 fire suppression system uses a standalone liquid agent designed to suppress fires in heavy industrial and off‑road mobile equipment across industries such as mining, forestry, construction, waste management, power generation, and agribusiness.
Why LVS NF‑40 stands out:
- Strong fire knockdown and cooling performance
- Helps prevent reflash by blanketing fuel and cutting off oxygen
- Non‑fluorinated, biodegradable, and PFAS‑free, making it an environmentally safer option
- Leaves less residue for easier cleanup and faster return to service
The liquid agent flows along the same path as burning fuel, reaching areas that are often difficult for firefighters to access.
System details:
- Agent stored in 5, 10, 15, or 30‑gallon tanks
- Operates in temperatures from ‑40°F to 120°F (‑40°C to 49°C)
Built with corrosion‑resistant components for rugged environments
Why choose LVS NF‑40 over dry chemical?
- Environmentally safer liquid agent
- Improved cooling to reduce reignition risk
- Less residue and faster cleanup
- Excellent performance on Class A and B fires, including fuel and hydraulic oil fires
For many applications, LVS NF‑40 provides both fire suppression and cooling in a single system.
Detection and actuation: CHECKFIRE Systems
For 24‑hour protection, Ansul CHECKFIRE detection and actuation systems provide automatic detection, alarms, equipment shutdown, and fire suppression activation.
CHECKFIRE 110
Designed for smaller vehicles operating in extreme conditions, the CHECKFIRE 110 offers cost‑effective, single‑zone detection and actuation for industries such as forestry, waste management, aviation, and transit.
CHECKFIRE 210 and 210 QIR
The CHECKFIRE 210 system provides supervised input/output circuits and real‑time system status alerts. Upon detecting a fire, it activates the suppression system automatically.
The CHECKFIRE 210 Quad Infrared (QIR) detector delivers faster detection and response, making it well‑suited for the off‑road mining industry where early detection is critical.
Benefits include:
- Faster flame detection
- Reduced severity of vehicle fires
- Improved operator safety
- Minimized equipment damage and downtime
CHECKFIRE SC N and MP N
Although the CHECKFIRE SC‑N has been discontinued by the manufacturer, Levitt‑Safety continues to service and support existing installations and can help customers explore conversion options.
The CHECKFIRE MP‑N system is designed for extreme environments and complies with underground coal mine safety standards. Both systems offer self‑contained battery operation for continuous protection without external power.
