PRODUCT OVERVIEW
Foam solution.
Air. Controlled discharge.
The Frozenfire MX 450 is a portable medium expansion foam branch for Class B hydrocarbon liquid fire applications. A matching 450 LPM inline foam inductor proportions concentrate into the water before the solution enters the branch.
Atmospheric air is drawn through the induction ports and combined with foam solution across the stainless-steel mesh. The resulting foam blanket is intended for fuel-surface coverage, vapour suppression and protection against re-ignition, subject to the selected concentrate and system design.
The MX 450 catalogue lists aluminium alloy / stainless-steel construction, a carrying handle, pressure-gauge provision and a powder-coated finish for industrial environments.
Portable assembly
A carrying handle, corrosion-resistant components and powder-coated finish support handling and deployment.
Pressure monitoring
The MX configuration is shown with a pressure gauge. Confirm the specified glycerin-filled gauge and supply scope when ordering.
Matched proportioning
A matching inline inductor supplies foam solution at the branch’s rated flow and the selected 3% or 6% concentration.

OPERATION
Prepare the system.
Establish the foam discharge.
Catalogue guidance used with the approved fire-protection system procedures and selected foam concentrate.
- 01
Inspect before use
Inspect the branch, mesh, gauge, inductor, suction hose, seals and couplings. Verify concentrate suitability and secure all connections.
- 02
Connect the matched system
Connect the fire-pump hose to the inductor inlet and the inductor outlet to the branch. Place the pickup tube in the concentrate and check the flow-direction arrow.
- 03
Establish the operating pressure
Open the water supply gradually and establish the catalogue duty of 7 kg/cm². Check continuous concentrate induction at the selected 3% or 6% setting.
- 04
Generate & apply foam
Atmospheric air mixes with the solution across the stainless-steel mesh. Hold the branch securely and apply foam using the approved roll-on, bank-down or rain-down technique for the hazard. Avoid disturbing the fuel surface.
- 05
Flush, drain & inspect
Flush the branch, inductor, mesh, pickup hose and strainer with clean water. Drain, dry and inspect the assembly before storage.
CONFIGURATION & ENQUIRIES
Specify the complete
operating arrangement.
Confirm the generator, proportioning, connections and installation together.
Foam & duty
Specify the concentrate, required 3% or 6% proportion, available water supply and protected hazard.
Matching inline inductor
Select the 450 LPM inductor with pickup hose, dip tube and metering arrangement suitable for the concentrate. Confirm whether the inductor is included in the supply.
Inlet & materials
Specify the 2½-inch instantaneous mating connection, body material and pressure-gauge requirement.
Discuss a configuration

INSPECTION & MAINTENANCE
Keep the air path clear.
Maintain the assembly.
Inspection, maintenance and storage guidance from the matching MX branch catalogue. Follow the approved procedures for the complete foam system.
01After every use
- Flush the foam branch and inline inductor with clean water to remove concentrate residue.
- Clean the stainless-steel mesh, suction hose and strainer.
- Drain and dry the equipment; inspect the pressure gauge and couplings.
02Monthly inspection
- Check the mesh for blockage or damage and verify gauge operation.
- Verify inductor performance and inspect seals, O-rings and couplings.
- Check the suction hose for cracks or leaks and tighten fasteners.
03Annual service
- Conduct a full flow and foam-performance test and verify the 3% or 6% induction percentage.
- Inspect internal corrosion; replace worn seals, O-rings and damaged components.
- Recalibrate or replace the gauge as required and service the complete assembly.
04Storage
- Store fully drained and dry in a clean, well-ventilated location.
- Protect from direct sunlight, corrosive conditions and dust.
- Keep the suction hose and strainer clean and cover the unit during long-term storage.
