How to Reduce Factory Heat in Malaysia: 5 Proven Solutions
Malaysian factories with metal deck roofs can experience internal temperatures exceeding 45°C during peak hours. This leads to:
- 🥵 Reduced worker productivity and health issues
- 💸 Skyrocketing electricity bills from air conditioning
- ⚠️ Damage to heat-sensitive equipment and inventory
Here are 5 proven solutions to cool your factory, ranked by cost-effectiveness.
1. Hybrid Turbine Ventilators (Best ROI)
What it is: Roof-mounted ventilators that use wind and a solar-powered motor to extract hot air 24/7.
Why it works: Creates a "chimney effect" that pulls hot air out and draws cooler air in naturally.
| Feature | Passive Ventilator | Hybrid (Solar) Ventilator |
|---|---|---|
| Power Source | Wind only | Wind + Solar Motor |
| Airflow (CFM) | 500 - 1,000 | 1,500 - 3,000 |
| Temperature Drop | 1°C - 2°C | 3°C - 5°C |
| Cost per Unit | RM 150 - RM 300 | RM 700 - RM 1,200 |
TTK Recommendation: Install 1 hybrid unit per 150-200 sqm of roof area for optimal cooling.
2. Industrial Exhaust Fans
What it is: Electric-powered fans mounted on walls or roofs.
Pros: High airflow capacity (10,000+ CFM), good for localized heat sources.
Cons: Ongoing electricity costs, maintenance required.
Best for: Kitchens, welding areas, or specific hot zones within a larger facility.
3. Roof Insulation
What it is: Reflective foil or foam insulation installed under the roof.
Why it works: Blocks radiant heat from penetrating through the metal deck.
Cost: RM 5 - RM 15 per sqft depending on material.
TTK Tip: Combine roof insulation with ventilators for the best results.
4. Cool Roof Coatings
What it is: Reflective paint applied to the roof surface.
Why it works: Reflects sunlight, reducing the amount of heat absorbed by the metal.
Lifespan: 5 - 10 years depending on product quality.
5. HVLS Fans (High-Volume Low-Speed)
What it is: Large ceiling fans (up to 7 meters diameter) that circulate air slowly.
Pros: Creates a cooling breeze, works well with ventilation.
Cons: High upfront cost, requires ceiling height.
Conclusion: Start with Ventilators
For most Malaysian factories and warehouses, Hybrid Turbine Ventilators offer the best return on investment:
- ✅ Zero electricity cost
- ✅ Works 24/7, even on calm days (solar motor kicks in)
- ✅ Minimal maintenance (sealed bearings)
- ✅ Quick payback (typically under 12 months)
