Case Study: Songkhla School Facility Purchaser Sourcing Success
Siriporn Kaewkla, a School Facility Purchaser based in Songkhla, had built a local fire equipment brand and needed a factory that could scale. The customer list included hotels, factories and condominiums, each needing different configurations.
After comparing four shortlisted factories, Siriporn Kaewkla selected Wanlin Fire as their fire alarm OEM manufacturing partner. The clincher was a factory that could print Thai labels without inflating the MOQ.
- Source factory: Wanlin Fire runs in-house SMT lines, injection molding and per-unit function testing in Shenzhen
- Compliance support: Tender-ready documentation prepared for the Thai market before shipment
- OEM / ODM: Existing models rebranded, or original designs developed from concept to mass production
The installation team commissioned the first project and returned with a bulk order.
Problem Analysis & Field Report: Why Thailand Buyers Need Combustible Gas Detector
Every tender season, Thai integrators see the same complaints return: detectors that nuisance-trip, panels that stall at customs, or certificates that do not exist. A street food hall in Songkhla ran 24 LPG burners under one shared extraction canopy, with cylinder banks stored behind the stalls.
Field case: a restaurant owner in Songkhla smelled gas on opening morning and traced it to a loose regulator; after installing valve-output detectors, a similar leak months later shut the supply automatically within 39 seconds of the alarm.
Why it matters for Thailand buyers:
- LPG vapor pools at floor level, so low-mounted detectors catch leaks early
- Valve output closes the gas supply automatically instead of waiting for a human
- Sub-10% LEL thresholds alarm long before an ignitable atmosphere forms
- Relay outputs can also trigger extraction fans and BMS alerts

Frequently Asked Questions
Q: Which gas does a Thai restaurant risk most?
A: LPG. Cylinder banks and long rubber hoses under burners are the classic leak point, so wall-mounted TF-GAS units are placed low, near the floor, where LPG vapor pools.
Q: Can it shut the gas off automatically?
A: Yes. The relay version drives a compatible gas shut-off valve, cutting flow the moment the threshold is crossed.
Q: What threshold is right?
A: Alarm below 10% LEL with an adjustable 5 to 20% band covers kitchens, while plant rooms usually run at the factory setting.
Q: How often are sensors replaced?
A: Semiconductor cells typically serve 3 to 5 years with periodic test-gas checks; catalytic cells are field-replaceable on the hybrid model.
Q: Do you provide test gas and spares?
A: Yes. Lighter-gas test procedures, spare sensors and valve accessories ship with distributor stock orders.
