High temperatures in a factory are not just uncomfortable; they pose a direct threat to worker health, machinery lifespan, and product quality. This article will compile the most comprehensive factory cooling solutions, helping businesses choose the optimal option for their budget and operational conditions.
Why is it crucial to control factory temperature?
A workplace that is too hot can lead to serious consequences:
- Worker health & safety decline: High temperatures cause dehydration, heatstroke, and exhaustion, reducing concentration and increasing the risk of accidents.
- Impact on machine performance: Industrial equipment operating in excessive heat will have a shorter lifespan, experience more frequent breakdowns, and may operate inaccurately.
- Reduced product quality: Many industries such as food, pharmaceuticals, electronics, and textiles require stable temperature environments to ensure output quality.
- Skyrocketing energy costs: The continuous need for cooling equipment leads to higher electricity bills, affecting profitability.
Effective factory cooling solutions
Group 1: Low-cost & natural solutions
These are fundamental, easy-to-implement methods focused on blocking external heat sources.
- Planting trees for shade: Plant greenery, especially trees with wide canopies, in directions that receive a lot of sun (west, south) to create natural shade, reducing direct heat radiation onto the factory walls and roof.
- Reorganizing the production space: Position large, heat-generating machinery near windows, vents, or exhaust fans to allow heat to escape easily. Ensure that pathways and the space around equipment are always clear.
- Regularly cleaning the roof and walls: A clean, light-colored roof reflects sunlight better than a dirty, dark-colored one.
Group 2: Heat-proofing, insulation, and ventilation solutions
These solutions require an initial investment but provide long-term, sustainable heat-proofing benefits.
- Insulating paint for heat reduction: Use specialized paints for metal roofs and exterior walls. This paint layer can reflect 80-90% of sunlight, helping to reduce surface temperatures by 10-20°C, thereby significantly cooling the space inside.
- Using insulation jackets for machinery and hot pipes: For large heat-generating equipment (boilers, compressors, hot steam pipes), using insulation materials (removable insulation jackets, fiberglass) to cover them will prevent heat from radiating into the surrounding environment, lowering the overall temperature of the work area.
- Optimizing natural ventilation:
- Installing louvers and windows: Arrange them strategically at opposite positions to create cross-ventilation, pushing hot air out and drawing cool air in.
- Using roof ventilation turbines: Installed on the roof, these turbines operate on the principles of convection and natural wind to extract hot air trapped under the roof 24/7 without consuming electricity.
- Installing industrial ventilation fans:
- Wall-mounted exhaust fans: Extract and expel hot air, dust, and odors from a specific area.
- Roof exhaust fans: More powerful than ventilation turbines, they help quickly extract large amounts of stagnant hot air from high up.
Group 3: Investing in specialized cooling systems
When the above solutions are insufficient, investing in a specialized system will provide rapid, large-scale cooling.
- Positive pressure cooling system (Evaporative Cooling):
- This is currently the most effective and energy-efficient solution. The system uses industrial air coolers to blow a stream of cool, clean air (filtered and cooled via a cooling pad) into the factory.
- This airflow creates positive pressure, continuously pushing hot, polluted air out through openings. This solution provides 100% fresh, oxygen-rich air, which is very beneficial for workers’ health.
- Misting cooling systems:
- These systems use nozzles to create ultra-fine mist particles that evaporate quickly in the air, absorbing heat and helping to reduce the ambient temperature by 5-7°C.
- This solution is particularly suitable for open or semi-open spaces, helping to suppress dust and create an immediate sense of comfort.
- Using insulated roofing panels: Replace or install insulated panels (like PU, EPS panels) that offer superior heat and noise resistance, providing sustainable cooling for the factory structure.
Conclusion
No single solution is perfect. A smart factory cooling strategy often involves a combination of methods: start with good insulation and ventilation (Groups 1 & 2), then consider investing in a specialized cooling system (Group 3) that fits the scale and type of production. This not only creates a safe and productive working environment but is also a smart investment that helps save energy costs in the long run.

How can I reduce factory temperature at the lowest cost?
You can start by planting trees for shade, cleaning the roof to make it lighter in color, and reorganizing machinery to optimize natural airflow.
Is heat-insulating paint for metal roofs really effective?
Very effective. High-quality insulating paint can reflect a large portion of solar radiation, helping to reduce the roof surface temperature by 10-20°C, making the space inside significantly cooler.
Should I choose ventilation fans or a positive pressure cooling system?
Ventilation fans mainly help circulate air and exhaust hot air. A positive pressure cooling system not only ventilates but also actively cools the air and supplies fresh air, providing a more comprehensive cooling effect.
What is the best solution for a factory with a metal roof?
Combining heat-insulating paint for the metal roof, installing roof ventilation turbines or exhaust fans, and using a positive pressure cooling system is the most comprehensive and effective solution for a factory with a metal roof.
What is the standard temperature in a production factory?
According to regulations from Vietnam’s Ministry of Health, the workplace temperature must be maintained not to exceed 32°C. However, the ideal temperature range to ensure health and productivity is around 26-28°C.
Does using insulation jackets for machinery help cool the factory?
Yes. Using removable insulation jackets prevents heat from machinery and pipes from radiating into the surrounding environment, which reduces localized temperatures and contributes to lowering the factory’s overall temperature.
