The air destratifier is the most cost-effective equipment for any company with high-ceiling premises (warehouses, gyms, hangars, reception halls). In a building over 4 meters high, thermal physics imposes a simple and costly rule: hot air, being lighter, rises and accumulates under the roof, while cold air stagnates at ground level. This phenomenon, known as thermal stratification, leads to colossal energy waste. At Climatik, we install efficient destratification systems to homogenize temperature, improve employee comfort, and drastically reduce fuel consumption.

Understanding the phenomenon of thermal stratification

To understand the usefulness of an air destratifier, one must examine the temperature gradient. In an unequipped industrial building, a temperature increase of 1°C to 1.5°C per meter of height is generally observed.

The thermal assessment

If you want to maintain a temperature of 18°C on the ground for your operators in an 8-meter high hangar, it will probably be more than 28°C under the ceiling.

• Direct consequence: You are heating an unnecessary volume of air.

• Increased heat loss: The heat accumulated at the top escapes faster through the roof (often the least insulated wall), forcing your hot air generator to run continuously.

1. How does an air destratifier work?

An air destratifier is not just a fan. It is a thermal turbine designed to circulate air vertically and in a controlled manner.

The heat recovery cycle

The device, fixed at the highest point of the building, draws in the hot air accumulated under the roof and gently propels it downwards. This airflow "breaks" the thermal layers and mixes the hot air from the top with the cool air from the bottom.

• Uniformization: The temperature difference between the floor and the ceiling is reduced to only 1 or 2°C.

• Regulation: The thermostats of your heating devices (air heaters, radiant heaters) detect this temperature rise at ground level and switch off much faster.

2. Major benefits for your company

The installation of air destratifiers by Climatik offers an extremely rapid return on investment (ROI), often in less than two heating seasons.

Massive energy savings

By recovering heat lost at the ceiling, you reduce the need for thermal production from your boiler or hot air generators.

The Climatik key figure: Heating savings are estimated to be between 20% and 35% depending on the building's height and insulation.

Increased working comfort (CSR)

No more "cold feet"! By bringing heat down to workstation level, you improve the working conditions of your employees. A stable thermal environment reduces absenteeism and increases productivity. In addition, the destratifier prevents violent drafts by creating a slow and diffuse air movement.

Protection of stock and building

In logistics warehouses, stratification can harm the preservation of certain heat-sensitive products stored at height (pharmaceuticals, food). Furthermore, by homogenizing the air, the destratifier limits the risks of condensation on metal structures and the roof, extending the building's lifespan.

3. Choosing the right type of destratifier with Climatik

There are several technologies of air destratifiers, and the choice depends on the configuration of your premises.

Turbine destratifiers (Ducted fans)

These are compact devices with a casing that channels the airflow into a narrow cone. They are perfect for very high ceilings (up to 20 meters) because they have a significant projection range.

• Usage: High-bay storage warehouses, factories.

HVLS (High Volume Low Speed) destratifiers

These are huge ceiling fans (up to 7 meters in diameter) that rotate slowly. They move a colossal mass of air at very low speed.

• Usage: Shopping centers, gyms, livestock buildings.

• Summer advantage: They are also very effective for cooling in summer by creating a light breeze.

Implementation and sizing

A destratification project does not consist of randomly installing fans. At Climatik, we conduct a flow study to optimize efficiency.

The air circulation rate rule

For effective destratification, the air volume circulated per hour must be approximately 2 to 3 times the total volume of the building.

Dtotal = Vbuilding x 3

Strategic positioning

Destratifiers must be placed:

1. Above main work areas.

2. Away from cold walls or loading dock doors to avoid drawing in cold air.

3. At a height that allows capture of the warmest air layer (approximately 50 cm below the ceiling).

Climatik's expertise: Why trust us?

Air is our business, and we know that each building has its own thermal signature. By choosing Climatik, you benefit from:

• High-quality equipment: Our destratifiers are equipped with low-consumption EC (electronically commutated) motors, which are extremely quiet and robust.

• Intelligent regulation: We install automatic control units equipped with two probes (one high and one low). The system only activates when the temperature difference justifies air circulation, thereby optimizing electricity consumption.

• Turnkey installation: Our technicians ensure safe high-level installation, in compliance with industrial electrical standards.

The little Climatik plus for summer:

Did you know that your destratifiers are useful all year round? In summer, by increasing their rotation speed, they provide an immediate feeling of freshness to occupants thanks to wind chill, without consuming the energy of air conditioning.

Conclusion

The air destratifier is the essential tool for energy transition in industrial buildings. It is a simple, robust, and incredibly effective solution to combat heat waste. At Climatik, we are convinced that the best energy is the energy not consumed. By recovering the calories sleeping at the ceiling, you are doing something for the planet and for your profitability.
