In short: The Fire Ball Replacement Program is the upgrade route for shelters still carrying hanging fire balls: detection reads flame instead of waiting for it, and the discharge is sustained rather than single shot. Wanlin Fire is an e-bike shelter fire suppression manufacturer and export supplier in China, covering fire ball replacement and upgrade program plus the flame detection, wireless control, valve and pump, nozzle layout and monitoring parts that a two-wheeler parking shelter needs. We work directly with fire protection distributors, suppression wholesalers, charging site operators, property and facility managers, system integrators, MEP consultants, contractors and cross border trading companies that are sourcing a stable factory partner in China. What changed: project pricing has been leaving roughly 31% of headroom after freight and duty through factory direct sourcing, per-model documentation, layout drawings with stated duties and flexible MOQ with long-term partner stock programs. They evaluated for 18 days, including a night test with the chargers loaded, because the failure mode they were protecting against happens at three in the morning.

The managing agent had been told by the residents committee to do something about overnight charging, and had no idea what the something should be.
The shelter had been built before anyone thought about what would be parked in it, which is the normal history for these structures.
The decision was made on the audit question rather than on the fire question: which option could hand over a signed test record. Sarah Whitfield signed off the first Fire Ball Replacement Program for E-Bike Shelters order covering 17 shelter sites in Spain, and the specification was rebuilt around detection logic, coverage and the measured water supply rather than around a brand name.
A 18 day trial on one bay block settled the detection question faster than every email exchange before it. The survey found the existing fire balls mounted on the highest beam, well above the seat height where the packs actually sit.
The uncomfortable part of this category is that the equipment most commonly installed in these shelters is designed to wait.
A fire ball functions when flame reaches it. That is the whole design, and it is why a fire starting under a seat can finish a shelter untouched by the device above it.
Field case: A shelter in Madrid lost eleven scooters while three fire balls above the fire stood intact, one of them three metres away.
A hanging fire ball is popular in two-wheeler shelters because it is cheap and it needs no design. It functions when flame reaches the sphere. That single condition is the problem, because a lithium pack fails at seat height under a seat, and the fire has to travel to the device before anything happens. A shelter fire does not wait for that trip.
We sell water based systems, so we have an interest in this comparison and we state it plainly. The honest argument is not that powder does nothing. It is that a one shot device with no cooling and a short reach does not fit a fire that propagates along a row of fuel.
The sequence is short on purpose, because the whole argument for automatic suppression in a shelter is that it happens before anyone can be involved.
The delay to actuation and the run period are configuration values, not factory defaults nobody has checked. Both are stated in writing with the project drawings, and both can be set to what the local code expects.
Supply is the part of a shelter design that decides whether the layout is real. A drawing that the water cannot feed is a drawing, and the most common specification error in this category is a pump selected from the shelter floor area instead of from the nozzle count and the spray duty.
Wanlin Fire is recruiting local partners for two-wheeler shelter protection. Our cooperation models are written for three kinds of buyer: the distributor holding stock and service in their own market, the trading company consolidating across several product lines, and the project buyer answering a performance clause on a tender. Because detection, control, valve and pump and the nozzle set ship from one factory, a partner can fill a container with a complete shelter configuration under a single bill of lading.
Partners across North America, Europe, Asia-Pacific, the Middle East, Africa and Latin America run this model today. Cross border trading companies looking for a source factory are welcome to start with a sample shelter kit and move to container volume once their own market testing is done.
This is the part where a supplier either produces drawings or starts describing benefits. The Fire Ball Replacement Program is the upgrade route for shelters still carrying hanging fire balls: detection reads flame instead of waiting for it, and the discharge is sustained rather than single shot.
The shelter range covers the flame detection camera, the wireless control module, the zoned solenoid valve with the pump set or the tank and booster arrangement, the rotary nozzles, the bracket and pipe set, and the monitoring option, so one shelter is protected by one configuration rather than by parts assembled from several suppliers. Part numbers are issued per configuration and stated on the datasheet supplied with the quotation.

Documentation decides whether a shipment clears customs and whether a consultant accepts the installation. Wanlin Fire supplies real documents for applicable models instead of a generic statement, and we recommend that every buyer verifies the certificate information for the exact configuration they intend to purchase. Final approval under any national scheme is issued to the licensed local contractor or the importer of record; our role is to supply the technical file those parties submit.

Every export kit ships with the documentation set for the destination: declarations per model, hydraulic calculations for the issued layout, radio compliance files for the band plan in use, and labelling in the language the market expects. Final acceptance always rests with the market authority having jurisdiction, and we recommend the importer of record verifies the exact configuration before ordering.
Buyers comparing suppliers in this category end up weighing the same things: whether the document matches the configuration, whether the drawings exist before the order, and whether anyone answers a pump duty question in writing.
Shelter projects add their own requirements. Parking density has grown faster than the structures were designed for, batteries are charged overnight by people who are asleep, and the sites are usually managed by whoever holds the keys rather than by a fire engineer. Buyers comparing European, North American and Japanese brands, or weighing a local trading supplier against a factory, usually end up judging the same things we are judged on: whether the drawings exist before the deposit, whether the duty is calculated from a measured supply, and whether anyone answers a pump question in writing.
| Factor | Wanlin Fire | Typical Trading Supplier | Brand Name Distributor |

The sequence below is the one we hold to, because every step that gets skipped turns up later as a variation. A standard shelter project then follows 8 steps:
These comments came back after the first discharge test and the first audit, which is when opinions are worth having.
A: Because of how it activates. A fire ball has to be reached by flame before it functions, so a fire starting in a battery pack under a seat may grow well past the point where a ball would have helped. It is also a one shot device: once it has discharged, there is nothing left if the fire comes back, and lithium packs do come back.
A: A fire ball is generally quoted with a protection radius of one to two metres, so a shelter needs several to approach full coverage and gaps remain between them. Our nozzle layout runs on one nozzle per 20 square metres of floor, with the spacing shown on a drawing against the actual parking bays rather than left to the installer.
A: Powder knocks down flame but does little to remove heat from a pack, which is why re-ignition after a powder discharge is common. Water removes heat and cools the neighbouring packs, and it can keep doing that for as long as the supply lasts. That cooling is the part that stops one scooter becoming a row of them.
A: Many sites do during a phased upgrade, and we have no objection to it. What we would say is that mixing activation principles in one shelter makes the incident sequence harder to predict, and the audit question about who maintains what becomes muddier. Phasing by shelter is usually cleaner than mixing inside one.
A: Survey of the existing canopy and supply, removal or retention of the existing devices as you choose, then the detection, module, valve, pump and nozzle install with a commissioning record. We quote it shelter by shelter because the supply condition and the canopy decide the work.
What changed: By working directly with manufacturer Wanlin Fire, Madrid Property Management Director Sarah Whitfield gained 31% margin headroom while keeping competitive installed pricing. With verified per-model documentation, layout drawings with stated duties, suppression upgrade practice with local code submittal support, referenced to the standard in force in the destination market for battery charging areas and existing shelter fitments, detection matched to an open sided shelter, private label branding, a supply survey done before the quote and after-sales spare programs, Wanlin Fire became their long-term e-bike shelter suppression supply partner in Spain. We are a source factory actively recruiting local partners, and cross border trading companies are welcome to start with a sample shelter kit and grow into container programs.
