In summer, heat protection is a serious challenge at chemical plants — especially during inspection and maintenance in explosion-proof areas and around outdoor equipment. But conventional fan-equipped cooling wear runs on fans and batteries, so in explosion-proof areas — where electrical devices are restricted — its use must first be cleared, and explosion-proof models are costly. This case study shows how a chemical plant adopted the battery-free, evaporative "AT601 Aqua Water Vest" to solve heat protection, work mobility and cost in explosion-proof areas.
Key Takeaways
- Battery- and fan-free evaporative cooling (just add water), so it is easy to consider even in explosion-proof areas where electrical devices are restricted
- No battery charging or spare-battery management; it doesn't balloon, so workers stay mobile during crouching work and inspections around pipes and valves
- Lower adoption cost than explosion-proof battery-powered cooling wear, making it easy to roll out to the workers who need it

Background: Summer Heat Protection in Explosion-Proof and Outdoor Areas
At this chemical plant, heat protection for workers was a challenge during summer inspection and maintenance in explosion-proof areas and around outdoor equipment.
Conventional fan-equipped cooling wear runs on fans and batteries, so in explosion-proof areas its use has to be cleared first. Explosion-proof battery-powered cooling wear also tends to be expensive, making plant-wide adoption a heavy cost burden.
On top of that, battery-powered cooling wear is noticeably heavy, and the fans make the garment balloon, getting in the way during crouching work and inspections in tight spaces. Especially around pipes, valves and tanks — work done while constantly changing posture — this reduced productivity.
Challenges: Why Ordinary Cooling Wear Is Hard to Use in Explosion-Proof Areas
The plant wanted heat protection, but explosion-proof areas restrict bringing in electrical devices, making ordinary cooling wear hard to use as-is.
There was also operational overhead: forgotten charging, managing spare batteries, battery degradation, and dealing with failures. Adopting explosion-proof cooling wear was an option, but the high price made it hard to equip everyone who needed it.
What the site needed was heat-protection gear that is:
- Easy to use even in explosion-proof areas
- Free of battery management
- Less likely to get in the way during crouching work
- Easy to keep adoption cost down
Solution: the Battery-Free Evaporative Cooling Vest "AT601"
The answer we proposed was the battery-free "AT601 Aqua Water Vest". The AT601 is an evaporative cooling vest you use by filling it with water.
Because it uses no battery or fan, it is easy to consider even where electrical devices are restricted, with no charge management or spare batteries to prepare.
- No battery or fan — easy to consider even where electrical devices are restricted; no charge management or spare batteries needed.
- Doesn't balloon — unlike fan-equipped cooling wear, it doesn't puff up, so it stays out of the way during crouching, tight-space work and inspections around pipes and valves.
- Just add water — the recommended fill is about 400 ml; just add water before work, and because it uses water, running cost stays low.
| Comparison | Fan-equipped / explosion-proof battery cooling wear |
AT601 Aqua Water Vest |
|---|---|---|
| Use in explosion-proof areas | Electrical device — use must be cleared first | No battery or fan — easy to consider where devices are restricted |
| Operational overhead | Forgotten charging, spare-battery management, degradation, failures | No charging or spare-battery management |
| Crouching / tight-space work | Fans make it balloon and get in the way | Doesn't balloon — easy to move around pipes and valves |
| Adoption cost | Explosion-proof models are costly and hard to equip everyone | Uses water — low running cost, easy to roll out |
Results: Heat Protection in Explosion-Proof Areas, with Less Battery Hassle
Before work, the team filled the AT601 with water and wore it during inspection and maintenance in explosion-proof areas and around outdoor equipment.
- No battery to attach — unlike fan-equipped cooling wear, there is no pre-work charge check or spare-battery prep.
- Easy to move during crouching work — because it doesn't balloon, workers move easily while operating valves crouched or inspecting under pipes and around equipment, reducing strain.
- Rolled out at lower cost — even compared with explosion-proof battery-powered cooling wear, adoption cost is lower, so it is easy to deploy to the workers who need it.
As a result, the chemical plant achieved heat protection in explosion-proof areas, less battery-management hassle, and better mobility during crouching work.
