RML’s Compressed Air Suppression Technology (CAST) integrates finely controlled compressed air with water delivery to produce a high-performance suppression medium. This medium is optimised for managing fires in lithium-ion battery systems, mixed-material waste stockpiles and complex chemical storage where conventional sprinkler or foam systems may underperform.
Key performance features include:
• Rapid heat reduction, interruption of thermal-runaway events and prevention of re-ignition.
• Creation of a dense, aerated blanket that isolates the fire zone, limits oxygen ingress and suppresses flame spread.
• Significant reductions in water-run-off, contaminated effluent and post-incident remediation costs. Critical for environmentally sensitive sites.
-
• Ideal for battery-storage, recycling and waste-management applications: engineered for Class A, B and lithium-ion fire scenarios.
• Modular integration: fixed installation, skid-mounted units or mobile rapid-response systems.
• reduced clean-up burden: minimal residue, less effluent and simpler site remediation.
• Efficiency and sustainability aligns with ISO 14001 environmental management frameworks and circular-economy principles.
• Cost-efficient: designed to reduce asset damage, personnel downtime and disposal or containment costs following a fire event."

RML’s eco-suppression solutions are purpose-built to reflect the principles of circular economy and resource-efficient operations. By reducing water consumption, chemical impact, and contaminated waste streams, our systems deliver a true operational advantage for recycling and waste sites committed to sustainable performance. These solutions move well beyond traditional foam-based approaches, offering a cleaner, safer, and future-ready fire-control capability.
-
RML Fire foam suppression systems help prevent and mitigate fires in waste and recycling facilities, reducing the risks associated with combustible materials.
Our reliable foam suppression system ensures rapid response to potential fire incidents, minimizing damage to facilities and equipment. Also giving operators a longer throw to target.
Our fire suppression reduces the frequency and severity of fire-related disruptions, enabling smoother operations and less downtime.
-
By suppressing fires quickly, these systems can limit the release of toxic smoke and pollutants, contributing to a cleaner environment and adhering to regulatory compliance.
All RML AU systems use up to 85% less water. By minimising chemical residue and water contamination, our systems support your facility’s compliance with environmental-management obligations and corporate ESG commitments.
-
RML systems have proved a reduction in traditional infrastructure costs of 33%.
Facilities equipped with fire foam suppression systems may benefit from reduced insurance costs due to lower risk profiles.
Controlling fire risks minimizes potential losses that could arise from property damage and operational interruptions.
-
By ensuring safer operations, fire foam suppression aligns with the principles of the circular economy, which emphasises reusing and recycling materials.
-
RML systems comply with ESG governance in the following ways.
Environment – Less water use, lower carbon emissions, less toxic runoff water.
Social – Safer for staff, public and firefighters.
Governance – Aligned with ISO 14001, EPA and BCA compliance
-
Safety measures can enhance the reputation of waste and recycling facilities, fostering trust among consumers and stakeholders, which is vital for encouraging recycling behaviour.
-
We comply to the many regulatory frameworks in Australia which are mandated within each industry we work in.
-
RML AU live test data and up to date literature indicates that CAF offers superior performance through rapid extinguishment, deep cooling, and reduced re-ignition risk, representing a sustainable and effective approach for LIB fire control.
Thermal runaway is characterised by the development from smoke to open fire within seconds.
Accompanied by a spread of jet fires and long burning times without any possible intervention.
These situations deliver extremely high temperatures, dangerous gas emissions and the risk of explosions.
-
Our engineers have extensive knowledge and design experience in this space.
Compressed Air Foam Systems (CAFS) offer industry numerous operational and economic advantages.
Recognising these benefits, the National Fire Protection Association (NFPA) included an entire chapter on CAFS in the NFPA 11: Standard on Low, Medium and High-Expansion Foam (2010 edition).
According to NFPA 11, the minimum application rate is 1.63 L/min/m² for hydrocarbons and 2.3 L/min/m² for polar solvents, approximately one-quarter of the rate recommended for conventional low-expansion foam systems.
This reduction is directly attributed to CAFS’s enhanced foam structure and superior extinguishing characteristics.
-
The use of RML AU CAFS significant lower water consumption due to our lower application rate and alternating operation of sectors.
Much larger protected area is available with similar power consumption.
Significant smaller water reservoirs with infrastructure costs 33% less.
Very low load on structures due to the lower weight of compressed-air-foam instead of water.
-
In summary, RML AU fire foam suppression systems not only enhance safety and operational efficiency in Australia but also contribute to environmental protection, cost savings, regulatory compliance, and the overall framework of the circular economy. By integrating these systems, the industry can ensure more sustainable operations and a continued commitment to better management of resources.
Simply extinguishing the open flame is not an indication that the fire has been extinguished as the residual temperature of the battery is so high it causes re-ignition.
