Heat stress is a major risk in O&G facilities, but standard cooling is a safety violation. DUBICOOL engineers Explosion-Proof cooling solutions—from adiabatic chillers to spot misting—fully certified for Zone 1 and Zone 2 environments
The Challenge: Heat vs. Safety
The Thermal Risk in Volatile Zones.
In refineries and chemical plants, ambient temperatures often exceed 50°C. This creates a dual threat:
-
⚠️ Equipment Derating: Gas turbines, compressors, and transformers lose efficiency and trip in high heat.
-
👷 Worker Safety: Personnel wearing heavy fire-retardant (FR) PPE face life-threatening heat stress, reducing focus and safety compliance.
-
🚫 The Barrier: You cannot simply use a standard fan or AC. One spark from a non-rated motor could cause a catastrophic event.
The Solution: Certified “Ex” Cooling
Engineered to Suppress Heat, Not Ignite It.
DUBICOOL provides a complete range of hazardous area cooling equipment. Every component in the “Hot Zone” is strictly tested and certified to prevent ignition sources (sparks, hot surfaces, or static).
Technology A: ATEX Misting Fans & Ventilation
-
The Tech: Heavy-duty portable and fixed fans with spark-proof aluminum blades and Ex-d (flameproof) motors.
-
The Application: Spot cooling for maintenance crews during turnarounds or shutdowns on the rig floor.
-
Safety Spec: Zones 1 & 2 (Gas Group IIB/IIC), T3/T4 Temperature Class.
-
Mechanically driven pumps (if required) to remove electrical risks entirely.
Technology B: Adiabatic Pre-Cooling (Safe Area or Ex)
-
The Tech: Retrofitting air-cooled heat exchangers (ACHE) with adiabatic misting to lower process temperatures.
-
The Application: Cooling process gas or oil lines without increasing the footprint.
-
Safety Spec: Anti-static membranes and pneumatically driven pumps (if required) to remove electrical risks entirely.

Technical Trust Signals (The “Ex” Badge)
Compliance You Can Audit.
-
Global Standards: All equipment comes with ATEX (EU) or IECEx (International) certificates traceable to the manufacturer.
-
Spark-Free Materials: We utilize anti-static polymers, 316L Stainless Steel, and Marine Grade Aluminum to prevent friction sparks.
-
Temperature Class (T-Rating): Equipment is rated T3 or T4, ensuring surface temperatures never exceed the auto-ignition point of your specific gas hazard.
Safety is Non-Negotiable. Neither is Cooling.
