Published by Wanlin Fire (Wanlin Group) | Last updated: August 31, 2026 | Expertise: heritage building smart fire protection retrofit manufacturing
Grace Hall runs a Fire Equipment Wholesaler operation out of Hoi An, and wireless gas detector for heritage kitchens sourcing had become the bottleneck in his Southeast Asia delivery pipeline. Across Southeast Asia, heritage retrofit tenders are being won with documented wireless systems, so the sourcing decision shapes cost, delivery speed and after-sales for years.
After evaluating Chinese factories across 3 months, Grace Hall selected Wanlin Fire (Wanlin Group) as their heritage fire protection OEM manufacturing partner. They settled on Wanlin Fire for three reasons:
Sample burn-in ran 10 days on 40 devices across three building types, and all 40 passed with stable mesh links and zero false alarms before the mass order was placed.
When a heritage fire in Hoi An goes wrong, it rarely fails loudly - detection gaps, false alarms and unmonitored overnight hours show up only after the event log is reviewed. A historic hotel in Vietnam reported that its kitchen gas supply was checked manually each morning; an overnight leak over 12 hours would have filled the room before anyone arrived.
Field case: A monastery canteen in Hoi An added HF-GAS units after a pilot gas event; the detector alarmed at 10% LEL before the flame reached the leak, and the kitchen reopened with the valve interlock documented.
Why it matters for Vietnam buyers:
Wanlin Fire provides flexible OEM and ODM services for customers who want to build or expand their own heritage fire protection product lines, retrofit programs or local service brands. Our customization capabilities include:

Certification is one of the most important considerations when sourcing fire protection equipment internationally. Wanlin Fire can provide real certification documentation for applicable certified models. Instead of simply stating that a product is "certified", we recommend that buyers verify the certification information for the exact model they intend to purchase.

Wanlin Fire's heritage fire protection OEM services are suitable for: heritage fire protection distributors, historical building safety importers, temple fire alarm integrators, museum fire detection buyers, cultural heritage project managers, fire safety system integrators, conservation architects, historic site facilities managers, export trading companies, fire equipment wholesalers and smart city safety platform partners.
The OEM workflow is built around heritage requirements, certification verification and quality inspection. To receive a more accurate quotation, please provide: target country or market, heritage building type (temple, museum, archive, tower, historic district), required devices, estimated quantity, OEM requirements and connectivity requirements. A standard OEM project then follows 8 steps:
Feedback from verified distribution and integration partners in Southeast Asia and worldwide:
A: Standard models detect LPG / propane or natural gas / methane; dual calibration is available for mixed-fuel kitchens.
A: Yes. Models with a dry contact can trigger a solenoid gas valve, cutting supply when the leak threshold is reached - a common requirement in commercial heritage kitchens.
A: The detector alarms locally and forwards the event over the mesh to the HF-200 panel and cloud platform, which pushes app, SMS, email or voice alerts to the duty list.
A: Battery models run 2-3 years on lithium cells; mains-powered models include battery backup so leak protection survives a power cut.
A: The semiconductor sensor has a replacement program; periodic gas-response testing and calibration are recommended per national kitchen gas safety practice.
Net result: By working directly with manufacturer Wanlin Fire (Wanlin Group), Vietnam Fire Equipment Wholesaler Grace Hall achieved 35% higher margins while offering competitive pricing. With verified certification documentation, non-invasive wireless retrofit technology, private-label support and continuous product development, Wanlin Fire has become their trusted heritage fire protection OEM and ODM manufacturing partner.
