CoatTech Modular Explosion-Proof Wet Grinding Solution for Middle East Combustible Metal Finishing Lines
Client Profile: Industrial Metal Fabrication & Surface Finishing Sector (Middle East / GCC Region)
Equipment Provided: CoatTech Heavy-Duty Explosion-Proof Wet Downdraft Grinding Workstations (1.0M / 1.5M / 2.0M Series)
Application: High-safety deburring, grinding, and polishing of aluminum alloys, stainless steel, and light metal components
Primary Goal: Complete suppression of combustible metal dust explosion risks with high-efficiency wet extraction
1. Project Background & Safety Challenge
In modern metal processing facilities—particularly across the GCC region—grinding and polishing aluminum, titanium, and magnesium produces fine, combustible dust particles. When mixed with air in dry environments, these particles pose extreme fire and explosion hazards.
To meet stringent international industrial safety standards and local environmental regulations, a major Middle Eastern manufacturing facility partnered with CoatTech Intelligent Equipment Co., Ltd. to deploy an integrated, explosion-proof wet dust collection system.
CoatTech designed a flexible, modular wet grinding table solution available in 1.0-meter, 1.5-meter, and 2.0-meter workstation configurations, allowing the facility to optimize workshop space while maintaining 100% dust suppression safety.

3. Key Engineering Highlights & Safety Features
🛡️ 100% Explosion-Proof & Spark Suppression Architecture
1.Hydro-Filtration Scrubbing: Grinding sparks and heavy metal particles are instantly trapped in a continuous water curtain before reaching the exhaust fan, completely eliminating airborne dust concentration and thermal ignition risks.
2.Cast-Iron Ex-Fans & PP Pumps: Industrial-grade cast iron centrifugal fans prevent static electricity buildup, while anti-corrosive PP immersion pumps ensure continuous, low-maintenance water circulation.
🏭 Flexible Modular Design for Any Workshop Footprint
1.Compact 1.0M Unit: Ideal for specialized single-operator repair bays or precision tool grinding.
2.Mid-Size 1.5M Unit: Perfect balance of dual-fan airflow performance and floor space efficiency.
3.Heavy-Duty 2.0M Unit: Dual 3kW high-pressure fan configuration designed for continuous, multi-operator production lines with large workpiece processing requirements.
☀️ Tropicalized Build for Harsh Gulf Environments
Built with 1.2mm reinforced stainless steel frames and heavy-duty electrical control cabinets rated to operate smoothly under high ambient temperatures and heavy dust loads common in the Middle East.
