At HVAC&R Vietnam 2026 the company showcased explosion-proof fans and FRP (fibre-reinforced plastic) corrosion-resistant units, supporting expansion into Southeast Asian markets where humidity, chemicals, and hazardous areas shape equipment choices more than in temperate climates.
Why These Two Product Types Suit the Region
Southeast Asia's climate is hot and humid, and many industrial sites, from petrochemical plants to wastewater treatment, combine that moisture with corrosive or flammable atmospheres. A standard painted steel fan may corrode or, worse, become an ignition source in a hazardous area. The two product families on show answer those two problems directly, which is why they drew attention in a regional market with exactly those conditions.
Explosion-proof fans are built so their operation cannot ignite a surrounding flammable gas or dust: the motor and switches sit in protected enclosures, surface temperatures are limited, and the construction meets the relevant hazard classification. They are specified wherever vapour, gas, or combustible dust is present, such as storage, coating, and process areas, and the region's growing industry means more of those areas every year.
FRP units use a corrosion-resistant composite casing and impeller that shrug off the chemicals and salt air that eat steel. For coastal or chemical plants this extends service life sharply and keeps the fan efficient as the surfaces stay smooth, which matters because roughened blades lose performance over time and a corroded casing leaks.
The two families also suit different buyers at the same show: a paint plant needs the explosion-proof fan, a seafood processor needs the FRP unit, and a fertiliser site may need both. Showing both together is how a supplier shows it covers the region's real mix rather than one niche.
Product Parameters on Show
The table sets out the two families and their envelope, the figures a Southeast Asian specifier will weigh against the site condition.
| Item | Type | Note |
|---|---|---|
| Explosion-proof fan | protected motor, limited temp | hazardous areas |
| FRP unit | corrosion-resistant composite | chemical and coastal |
| Airflow | up to 50,000 m3/h | by model |
| Pressure | up to 2,000 Pa | process ducts |
| Market | Southeast Asia | humid, corrosive |
Showing both together lets a visitor see how one supplier can cover a plant's safe-area and hazardous-area ventilation, which simplifies specification and spare-parts planning, because the buyer deals with one engineering contact rather than two.
The FRP option also matters for hygiene: in food and pharmaceutical sites a smooth, non-corroding surface is easier to keep clean, which is a separate benefit from the corrosion resistance that first motivates the choice.
Checklist for Southeast Asian Buyers
Engineers specifying for the region should confirm these points, because the environment will expose any weak choice quickly.
- Classify the area: set the explosion-protection level from a proper hazard study.
- Pick the material: choose FRP where chemicals or salt will attack steel.
- Confirm the cert: match the protection to the applicable standard for the site.
- Plan spares: agree which blades and seals are stocked locally.
- Check the duty: size to real humidity and temperature, not a temperate default.
Why the Showcase Matters
Regional trade fairs are where Southeast Asian buyers compare who can actually support corrosive and hazardous duties locally. Showing working, certified units builds the case that the equipment will survive the environment it is sold for, which is the doubt a distant catalogue cannot answer.
For the manufacturer, local presence through such events shortens the path from a coastal plant's enquiry to a delivered, serviceable fan, and it signals a commitment to the region beyond a single shipment.
The showcase also gathers the feedback that shapes the next model, because a regional show is where the real site conditions are described by the people who live with them daily.
For FRP units in the region, buyers should also check ultraviolet stability if the casing sees sun, because some composites degrade under long tropical exposure and a unit outdoors or on a roof ages differently from one indoors. The supplier should state the resin grade and any UV inhibitor, and the buyer should match it to the mounting, since a corroded steel fan and a chalked FRP fan both fail, just differently. The explosion-proof fan, meanwhile, should carry the zone and temperature class on the nameplate so the site can confirm the fit without opening the standard. These two checks, often skipped in the rush of a regional order, are what keep the equipment alive through the climate it was bought for, which is the real test of the showcase claim. A unit that survives the climate is the proof the show implied, and the buyer who checks the resin and the nameplate is the one who gets that survival rather than a polite photograph from the booth.
