Cooling Industrial Halls: How Evaporative Air Coolers Cut Temperatures and Costs

Heat Stress in Industry – an Underestimated Problem

High temperatures in production and storage halls are no longer just a matter of comfort. When the thermometer climbs above 30 °C, it is not only productivity that suffers, but also the health of employees. Studies show that performance already declines from 26 °C, while concentration and error rates get worse.

Conventional air conditioning is often impractical in large industrial halls – it consumes enormous amounts of energy, requires complex installation and causes high running costs. Evaporative air coolers offer a flexible, cost-effective and sustainable alternative.

Why Conventional Air Conditioning Is Often Unsuitable for Halls

• High energy consumption: Air conditioners have to cool huge volumes of air, which causes enormous electricity costs.
• Complex installation: Piping, exhaust air systems, structural adaptations – expensive and time-consuming.
• Long payback period: Investments often only pay off after many years.
• Low flexibility: Once installed, systems can hardly be moved or extended.

How Evaporative Air Coolers Work

The principle of air cooling is remarkably simple:

1. Water is distributed over cooling pads.
2. A fan draws in warm air and passes it through the moistened pads.
3. The water evaporates and extracts heat from the air – the air that comes out feels noticeably cooler, up to 15 °C cooler by perceived temperature.

This process is not only energy-efficient but also environmentally friendly, as no chemical refrigerants are needed.

5 Advantages of Evaporative Air Coolers for Industrial Halls

1. Significant temperature reduction

Depending on the unit and the size of the hall, the air feels noticeably cooler – by 5–15 °C perceived temperature – often enough to meet the statutory recommendations for workplace temperatures.

2. Huge energy savings

An evaporative air cooler uses up to 80% less electricity than a conventional air conditioner. This has a direct impact on running costs.

3. Flexibility & mobility

The units can be set up without any conversion work, repositioned at any time or added to as needed. Perfect for dynamic production environments.

4. Health & occupational safety

Less heat stress means fewer accidents and errors, fewer sick days, higher employee satisfaction and productivity.

5. Fast payback

Thanks to the low investment and low running costs, an evaporative air cooler often pays for itself in the very first season.

Areas of Application in Industry

• Production halls: Machines and employees alike benefit from cooler air.
• Logistics centres: Prevents sensitive goods from overheating.
• Workshops: A pleasant climate ensures greater precision in manual work.
• Assembly & packaging areas: More safety and less downtime.

FAQ: Common Questions from Industrial Companies

Is a single air cooler enough for my hall?
That depends on the size. It often makes sense to place several units strategically to achieve even cooling.

What happens at very high humidity?
The cooling performance decreases somewhat but remains noticeable. In Central Europe, humidity is rarely so high that the effect would be insufficient.

Can I maintain the units myself?
Yes, maintenance can be handled by your own staff – no expensive service contracts needed.

Conclusion: Smart Cooling for Industry

Evaporative air coolers are the efficient solution for keeping industrial halls, workshops and storage areas pleasantly cool – without high energy costs and without complex conversion work. They not only boost productivity but also contribute to a healthy, safe working environment – while protecting both the environment and your budget.
