Steel workshops face extreme summer heat – often 10°C+ hotter than outside. Traditional AC is expensive, while roof insulation alone is ineffective. Here are proven ventilation & cooling methods:
1. Natural Ventilation (Lowest Cost)
- Roof Turbine Vents:
- Uses heat convection to expel hot air
- No electricity | Low install cost ($50-150/unit)
- Best for heat/smoke removal in high-bay areas
- Cross Ventilation:
- Install openable windows/roll-up doors on opposite walls
- Creates airflow (wind tunnel effect)
- Tip: Stagger window heights for better stack effect
✅ Pros: Zero energy cost, low maintenance
❌ Cons: Weather-dependent, limited in humid climates
2. Forced Ventilation (Moderate Budget)
- Exhaust Fans (Negative Pressure):
- Wall-mounted fans pull out hot air
- Creates air exchange rate 30-50x/hour
- Use corrosion-resistant models (IP54+)
- Evaporative Coolers:
- Cools air by 4-12°C using water evaporation
- Consumes 80% less power vs. AC
- Ideal for dry climates
✅ Pros: Fast heat removal, improves air quality
❌ Cons: Localized cooling, moderate humidity increase
3. Hybrid Systems (Best Cooling ROI)
- Evaporative Coolers + Exhaust Fans:
- Fans expel heat → Coolers supply fresh 17-27°C air
- Covers 80-150㎡ per unit
- Evaporative Coolers + HVLS Fans:
- Coolers supply chilled air → 3m HVLS fans circulate evenly
- 30% energy savings vs. ducted AC
- Eliminates hot spots
✅ Pros: 5-15°C temp drop, scalable for large workshops
Key Installation Notes
- Place turbine vents ≤6m apart for full coverage
- Install exhaust fans ≥4m height facing prevailing winds
- Use corrosion-resistant hardware (stainless steel bolts)
- Steel building cooling solutions
- Warehouse ventilation cost
- Industrial exhaust fan system
- Factory heat reduction
- Evaporative cooling ROI
- HVLS fan benefits
- Workshop temperature control
- Low-cost plant cooling
