Cooling Where a Spark is Fatal.
Certified Thermal Management for Zone 1 & Zone 2 Environments.
In the Oil & Gas industry, heat doesn’t just reduce efficiency—it increases risk. DUBICOOL delivers rugged, ATEX and IECEx certified cooling systems designed to withstand the corrosive offshore atmosphere and the explosive hazards of the refinery.
The Challenge: The “Thermal Trap” in Hazardous Zones
When Standard Cooling Isn’t an Option.
You cannot simply install a standard air conditioner or fan in a hazardous zone. Yet, ambient temperatures on a steel rig deck in the Gulf can exceed 55°C. This creates a “Thermal Trap”:
-
🔥 Equipment Derating: Compressors, pumps, and VFDs trip on high temperature, causing costly downtime.
-
👷 Workforce Heat Stress: Personnel working in heavy FR coveralls face dangerous heat exhaustion, leading to safety incidents and slower reaction times.
-
💥 The Spark Risk: Standard cooling equipment is a potential ignition source. You need cooling that is as safe as the rest of your rig.
The Solution: Certified “Ex” Cooling
Built for the Blast Zone.
DUBICOOL provides a complete range of hazardous area cooling solutions. Every component—from the motor to the gland—is certified to meet strict ATEX and IECEx standards.
Product A: Ex-Proof Portable & Wall Fans
The Application: Spot cooling for drill floors, maintenance workshops, and confined spaces. The Tech:
-
Ex-d Flameproof Motors: Contain any internal explosion without igniting the external atmosphere.
-
Anti-Static Blades: Carbon-fiber or antistatic polymer blades prevent static charge build-up.
-
Spark-Proof Guards: Stainless steel construction eliminates spark risks from impact.
Product B: Hazardous Area Spot Coolers (HVAC)
The Application: Temporary cooling for control rooms, switchgear modules, and accommodation containers. The Tech: Fully pressurized, explosion-proof portable AC units designed for Zone 1 deployment.
Product C: Mist Cooling for Safe Areas
The Application: Outdoor cooling for welfare areas, smoking shelters, and queue lines (Zone 2 or Safe Zone). The Tech: Flash-evaporation misting that cools the air without wetting the steel deck (preventing slip hazards).
Technical Compliance & Safety
Certified for Your Peace of Mind.
We understand that documentation is as important as the equipment itself. DUBICOOL provides full traceability and certification packages.
-
Zone Certification: Equipment rated for Zone 1 (Gas likely to exist) and Zone 2 (Gas unlikely to exist).
-
Gas Groups: Certified for IIA, IIB, and IIC (Hydrogen) environments.
-
T-Ratings: Temperature classes from T3 to T6 to ensure surface temperatures never reach the auto-ignition point of your specific gas hazards.
-
Ingress Protection: Minimum IP55 / IP66 ratings to withstand saltwater spray and sandstorms.
