ANSUL A-101/LVS Twin Agent

ANSUL A-101/LVS Fire suppression systems can be used for heavy earth-moving and mining equipment such as large excavators/shovels, drag lines, haul trucks, and other machines that work around the clock, in rugged, hazardous environments and can become superheated. The system can also protect underground mining equipment and speciality vehicles such as slag pot and/or slab carriers and tunnel boring machines.

Mining and heavy earth-moving equipment
Twin-agent combination is designed to protect large speciality vehicles. Such as mining and heavy earth-moving equipment.

The combined performance of the ANSUL A-101/LVS Twin-Agent Fire Suppression System provides the ultimate protection. While FORAY dry chemical knocks down flames, the LVS agent cools surrounding areas and hard to reach areas, minimising the possibility of reflash.

ANSUL A-101/LVS Twin Agent Agents


A multi-purpose dry chemical agent is used to combat fires in combustible materials including wood, paper and plastics (Class A). Also, other fires include flammable liquids, gases and greases (Class B), and fires involving energized electrical equipment (Class C).


A wet chemical agent that is a blend of organic and inorganic salts, coupled with surface-active ingredients. As a result, the blend provides a strong measure of freeze protection along with the foaming properties associated with conventional Class B liquid agents. The agent flows into areas where flammable liquids settle, furthermore providing both suppression and cooling of superheated surfaces. Most noteworthy is that the agent, to blanketing the fuel, cuts off oxygen to help prevent any reflash.

The ANSUL A-101/LVS Twin Agent combination has been proven effective in applications where superheated equipment, like a turbocharger, is used. The ANSUL A-101/LVS is also FM approved.

Why invest in a Vehicle Suppression System?

Protecting mobile equipment of all shapes and sizes presents a unique set of challenges, often requiring multiple solutions. With ANSUL A-101/LVS Vehicle Fire Suppression Systems, protection is assured, 24-hours-a-day, 365 days-per-year. Investing in an ANSUL fire suppression system can minimise repairs and replacement materials. Furthermore, a fire suppression system can also keep insurance cost down, most of all reduce downtime and prevent operator injury. Torvac can design, install and service a system that offers the ultimate fire protection for a specific vehicle.

The ANSUL A-101/LVS fire suppression system agent provides both fire suppression and superior cooling of super-heated surfaces, while blanketing the fuel and cutting off oxygen to help prevent reflash. It flows readily into hard-to-reach areas along the same path flammable liquids may have flowed. The wet chemical agent provides a strong measure of freeze protection along with the foaming properties associated with conventional Class B liquid agents.
