Minwen Fire · foam suppression
Concentrate, bladder tanks, proportioners, chambers, makers, monitors, nozzles and foam-water deluge — eight component types from one facility. Before any of it is quotable, one question has to be settled: whether the concentrate your design names is still permitted where the system will be installed.
Component range
A foam package is assembled, not bought off a shelf. Which components you need follows from the hazard and the application method; the sizes follow from the flow the design calls for.
Best for Class B hydrocarbon and polar solvent fires. AFFF and FFFP at 1%, 3% or 6% depending on the application, in 200 to 1,000 L drums. PFAS notice: AFFF concentrates contain per- and polyfluoroalkyl substances, and regulatory restrictions apply in the EU, the US and other markets. Verify local acceptance before ordering — we can advise on fluorine-free alternatives where they are required.

Best for self-contained proportioning where no separate concentrate pump is wanted. A pressure-rated tank with an internal bladder keeps foam separate from water until discharge. 100 to 2,000 L, 1.0 to 1.6 MPa, carbon steel.

Best for getting the mix ratio right before the foam-making equipment sees it. Inline inductors, around-the-pump and balanced-pressure types, 200 to 5,000 L/min, at 1%, 3% or 6%. Brass or steel.

Best for fixed-roof storage tanks, delivering foam onto the liquid surface. Sub-surface and top-surface application per EN and NFPA 11. Capacity follows the system design; 0.35 to 0.7 MPa, carbon steel.

Best for three-dimensional flooding of enclosed spaces — warehouses, hangars, cable tunnels, basement car parks. Medium and high expansion from 20:1 to over 200:1, at 500 to 5,000 L/min. Aluminium or steel.

Best for long-range delivery across large open industrial areas. Fixed or portable oscillating monitors, remote-controlled or manual, 500 to 8,000 L/min with a 30 to 80 m range. Stainless steel or aluminium.

Best for first-responder and fixed-installation application. Hand-operated and fixed types, aspirating and non-aspirating, 60 to 480 L/min. Brass or aluminium. Also used on foam hose reel systems and in brigade field response.

Best for fixed-area flooding in hangars, transformer bays, spray booths and flammable liquid processing. An integrated deluge valve and foam injection assembly delivering a foam-water blanket on actuation. 0.35 to 1.2 MPa, carbon steel.

Capacity or flow, working pressure, material, minimum order and lead time. On a mixed BOQ these are quoted per line, because the components do not run on one schedule.
| Component | Capacity / flow | Working pressure | Material | MOQ |
|---|---|---|---|---|
| Foam concentrate (AFFF / FFFP) | 200–1,000 L drums | — | Steel drum | 200 L |
| Bladder tank | 100–2,000 L | 1.0–1.6 MPa | Carbon steel | 200 pcs |
| Proportioner | 200–5,000 L/min | 0.35–1.2 MPa | Brass / steel | 200 pcs |
| Foam chamber | Per system design | 0.35–0.7 MPa | Carbon steel | 200 pcs |
| Foam maker | 500–5,000 L/min, 20:1–200:1 | Per design | Aluminium / steel | 200 pcs |
| Foam monitor | 500–8,000 L/min, 30–80 m | Per design | SS / aluminium | 200 pcs |
| Foam nozzle | 60–480 L/min | Per design | Brass / aluminium | 200 pcs |
| Foam-water deluge | Per system design | 0.35–1.2 MPa | Carbon steel | 200 pcs |
| Lead time | Bulk 35–60 days from order confirmation across all components; sample review 15–20 days. Trade terms EXW, FOB Xiamen or CIF; payment T/T, 30% deposit and 70% before shipment. | |||
By application
A tank farm, a hangar, a warehouse and a loading gantry take different packages from the same eight components. Start from the situation.
Why here
Most contractors source foam components from four or five manufacturers, each with its own lead time, documentation and minimum order. All eight types are made in the Quanzhou facility, with no subcontracting on core components.
PFAS-aware sourcing. We flag the regulatory restrictions on AFFF rather than leaving you to discover them, and can advise on fluorine-free alternatives for markets where PFAS-containing foam is restricted — the EU, Australia and several US states. What we will not do is tell you your market permits something; that confirmation is yours to obtain.
Common questions
Eight core types: AFFF and FFFP concentrate, bladder tanks, proportioners, chambers, makers in medium and high expansion, monitors, nozzles, and foam-water deluge systems. Individually or as a complete package against a BOQ.
That is yours to confirm, and it is the first question on this page for a reason. AFFF contains PFAS, and restrictions or phase-outs apply in the EU, the United States, Australia and elsewhere. Check with your environmental regulator or fire protection engineer, tell us the outcome, and we will quote to match — including fluorine-free alternatives where those are what your market accepts.
All the components, yes. Send the tank schedule with roof types: fixed-roof takes chambers, floating-roof takes makers, and quoting without that distinction produces a bill of materials that cannot be installed. We do not design the system or certify it — that is your fire protection engineer’s work.
1%, 3% and 6%. The route has to match the proportioner and the discharge device, so it is settled early rather than adjusted later. Drums run 200 to 1,000 L with a 200 L minimum.
Bladder tank capacities, monitor flow rates and nozzle fittings can be built to project specification, with a pre-production sample before the full run. Send the drawing or the specification sheet rather than a description.
Bulk 35–60 days from order confirmation, sample review 15–20 days. On a repeat component order with stable specifications a rolling supply schedule can be agreed to fit a project programme.
Test reports, material specifications, production records and the ISO 9001 certificate, as a package for tender submission. Third-party pre-shipment inspection is supported, including SGS, Bureau Veritas and Intertek.
The hardware does not. Foam concentrate is shipped in steel drums and its classification depends on the formulation and the destination’s rules, so confirm the concentrate’s status for your route at inquiry rather than at booking.
Yes. Concentrate drums, tanks and hardware can travel with extinguishers, sprinklers, hydrants and cabinets on one purchase order, with high-cube packing coordinated for the mixed cargo.
Line by line, with lead time against each line rather than one figure for the order — concentrate and a motor-driven monitor do not run on the same schedule. Response on a BOQ is typically two business days, since the technical review happens before the reply.
BOQ review
Hazard and fuel, application area, the flow the design requires, and the destination market. We come back with a line-by-line component quotation, the certifications that apply, and a production timeline — and we will say plainly if the concentrate you have specified is a problem where it is going.
