When Every Second Matters: Wellav Public Address Solution for Sinopec Oil Depot Safety

Close your eyes and picture a calm, clear voice cutting through roaring machinery—telling you exactly what to do when it matters most.

That’s the power Wellav put in place at a Sinopec oil storage hub in Jiangsu, China, with our explosion-proof IP public address system. This oil depot serves as the province’s central storage hub and ranks among the largest petrochemical warehouses in the Yangtze River region. Beyond organizing refined-oil supplies to meet market demand, this flagship depot also pilots green, low-carbon initiatives in support of the Yangtze River Protection campaign.

Wellav designed and deployed a full suite of high-performance IP public address products tailored to the depot’s sprawling footprint and unique operational environment. 

Here is how it goes:

Rock-solid gear built for harsh conditions

our explosion-proof horn speakers are certified Ex db IIB T3 Gb, meaning they can operate safely amid common volatile gases in oil depots like ethylene and gasoline. From multi-channel power sequencers to IP65-rated column speakers, every device laughs off dust, moisture, and magnetic interference.

Instant, pinpoint paging

5 networked stations let local teams zone in on specific areas, page individuals by name, or trigger facility-wide alarms with a single click—because when seconds count, you can’t afford hesitations.

Clear, loud alerts

In an emergency, these speakers instantly broadcast alarms to guide personnel evacuation, while also handling daily announcements, voice paging, and background music—even above the ambient noise of heavy machinery.

Always-on redundancy

Surge protectors and automatic main-to-standby switchers keep the system hot-standby ready, so even a primary failure won’t stop your message.

We’re proud to have helped this oil depot set a new benchmark in operational safety—and given every person on site a clearer, quicker line of communication when it matters most.
