Water foam fire tenders, also named as water foam fire truck, water foam firefighting truck. They are specialized firefighting vehicles designed to combat flammable liquid fires using foam-water mixtures. Water Foam Fire Tender is special fire rescue apparatus engineered to combat flammable liquid and structural fires through integrated water-foam delivery systems. The central component is a corrosion-resistant water tank (5,000–15,000 L capacity) constructed from reinforced polyethylene or stainless steel, coupled with a foam concentrate reservoir (500–2,000 L) equipped with an automated proportioning mixer to regulate foam-to-water ratios (1–6%).
A high-pressure centrifugal pump system, typically rated at 3,000–10,000 L/min with 8–15 bar output, powers dual discharge networks. The primary network feeds a roof-mounted, articulating foam/water monitor cannon with 360° rotation and 70° elevation, capable of projecting foam streams up to 90 meters.
Capacity-Based Foam Tenders
These are classified by their foam and water storage capacity. Compact units (1,000–3,000 liters) suit urban firefighting, while large-scale tenders (8,000+ liters) serve industrial zones. Mid-sized variants (3,000–8,000 liters) balance mobility and capacity for suburban areas.
Foam Delivery Mechanism
Tenders vary by discharge systems. High-pressure monitors project foam over long distances, ideal for oil refinery fires. Low-pressure systems with adjustable nozzles target localized flames, minimizing water damage.
Specialized Application Units
Airport crash tenders feature rapid acceleration and roof-mounted turrets for aviation fuel fires. Petrochemical variants include heat-resistant coatings and remote-controlled cannons for hazardous environments.
Water Foam Fire Tender comprises five primary structural systems. The chassis forms the operational base, typically a heavy-duty 4×4 or 6×6 all-terrain vehicle platform engineered for rapid response. Mounted atop is a corrosion-resistant stainless steel water tank (2,000-10,000L capacity) with internal baffles to stabilize liquid movement during transit.
Primary Applications of Water Foam Fire Tenders
Industrial and Chemical Facility Protection
Water Foam Fire Tenders (WFFTs) are critical in safeguarding industrial complexes, chemical plants, and storage units handling flammable liquids or gases. Their dual-suppression system combines water to cool surfaces and foam to smother flames, effectively tackling fires involving hydrocarbons, solvents, or volatile chemicals.
Airport and Aviation Emergency Response
Airports deploy WFFTs as frontline defense against aircraft-related fires. These vehicles rapidly discharge specialized aqueous film-forming foam (AFFF) to suppress fuel-driven blazes during takeoff, landing, or maintenance mishaps.
Urban Firefighting in Confined Spaces
In densely built urban areas, WFFTs address fires in underground parking lots, tunnels, or high-rise buildings. The foam’s high-expansion capability fills enclosed spaces, suffocating flames without excessive water damage
