Introduction

In scorching climates where temperatures routinely exceed 40°C (104°F), effective cooling isn't just about comfort—it's about safety and productivity. This guide breaks down how to select industrial-grade cooling solutions that combat extreme heat efficiently.

The High-Temperature Challenge: Key Considerations

1. Climate Profile

• Dry Heat (e.g., deserts): Prioritize evaporative cooling (works best<60% humidity)

• Humid Heat (e.g., tropics): Opt for HVLS fans + ventilation systems

• Intense Solar Radiation:  Roof-mounted units with UV-resistant housings

2. Space Requirements

3. Heat Sources

• Machinery-heavy sites: Add 20% extra cooling capacity

• High-occupancy areas: Prioritize air exchange rates (≥40 changes/hour)

Sizing Your System: A Data-Driven Approach

(Based on Siboly's Model Selection Guide)

Step 1: Calculate Air Changes Needed

Air Changes/Hour (N) = Total Airflow (CMH) ÷ Room Volume (m³)

Reference Chart:

Step 2: Determine Total Airflow

Total Airflow (CMH) = Room Length × Width × Height × N

Example:20m × 30m × 10m workshop needing 40 changes/hour

= 6,000m³ × 40 = 240,000 CMH

Step 3: Select Equipment

• 240,000 CMH requirement = 12 × Siboly 20,000 CMH roof-mounted coolers

• Add HVLS fans for 5-8°C perceived temperature reduction

Equipment Recommendations for Extreme Heat

1. Evaporative Coolers

• Best for: Dry regions (≤50% humidity)

• Top Picks:

• Roof-Mount Units (1.5KW-3KW) for large spaces

• Portable 20K+ CMH models with 100L+ tanks

• Key Features:

• Corrosion-resistant pads (5090 cellulose)

• Auto-refill systems for 24/7 operation

• HVLS Fans (7.3m diameter) + exhaust systems

• Desiccant dehumidifiers + spot-cooling units

• HEPA/Dust Filters (for sandy/dusty areas)

• Solar-powered options (reduce grid dependency)

• Remote monitoring (track humidity/temp via app)

Cost-Saving Strategies

• Energy Efficiency:  Evaporative coolers use 90% less power than AC

• Zoned Cooling: Target only occupied areas

• Preventive Maintenance:  Clean pads monthly → 30% efficiency boost

Real-World Case: Saudi auto plant reduced cooling costs by 62% using roof-mounted evaporative systems + HVLS fans.

Common Mistakes to Avoid

1. Under sizing equipment for heat-intensive processes

2. Neglecting humidity control in tropical zones

3. Using residential-grade units in industrial settings
