When it comes to industrial and commercial heating, energy efficiency is a top priority, especially in the ongoing cost of living crisis. One often overlooked factor in maintaining an optimal indoor climate is temperature stratification—the tendency of warm air to rise and collect near the ceiling while cooler air remains at ground level. This temperature imbalance can lead to increased energy costs and uneven heating. The solution? Destratification.
What is Destratification?
Destratification is the process of mixing the layers of air within a space to create a more uniform temperature from floor to ceiling. By redistributing warm air that naturally rises, destratification helps reduce heat loss, improve energy efficiency, and enhance occupant comfort.
Why Does Stratification Occur?
Stratification happens due to the natural properties of air movement. In large buildings, especially those with high ceilings—such as warehouses, manufacturing facilities, and retail stores—warm air produced by heating systems, machinery, and even people rises to the top, leaving cooler air at ground level. This imbalance forces heating systems to work harder to compensate for the heat loss, driving up energy consumption and costs.
Destratification fans are specialised air circulation devices designed to push trapped warm air back down to the occupied space. Unlike conventional ceiling fans, destratification fans operate strategically to maintain a consistent temperature throughout the facility. These fans can be installed in various locations depending on ceiling height and building layout.
How Destratification Fans Work
With any conventional air heating system warm air will rise to roof level by natural convection. In high buildings such as factories, warehouses and sports centres, this can result in high temperature gradients and consequently increased energy usage. Our destratification fans reverse the natural convection process, re-circulating warm air back to working level providing a permanent reduction in roof space temperature and uniform temperature distribution.

Key Benefits of Destratification
- Energy Savings – By reducing the need for excessive heating, destratification can lower energy bills by up to 30%.
- Improved Comfort – Even temperature distribution ensures a more comfortable working environment for employees and visitors.
- Reduced Carbon Footprint – Lower energy consumption means fewer carbon emissions, helping businesses meet sustainability goals.
- Heating System Efficiency – Less strain on heating systems can extend their lifespan and reduce maintenance costs.
- Prevention of Condensation and Dampness – Improved airflow can minimise condensation issues, which are common in large industrial buildings.
Where is Destratification Most Effective?
Destratification is ideal for any commercial or industrial space with high ceilings, including:
- Warehouses & Distribution Centers
- Factories & Manufacturing Plants
- Retail Stores & Shopping Centers
- Sports Halls & Gymnasiums
- Airports & Transport Hubs
How to Implement Destratification in Your Facility
To optimise destratification in your space, consider:
- Conducting an Airflow Assessment: Identifying areas where temperature stratification is most severe.
- Choosing the Right Fans: Selecting destratification fans based on ceiling height and floor area.
- Proper Fan Placement: Ensuring fans are positioned effectively to maximise air circulation.
- Regular Maintenance: Keeping fans in good working condition to sustain efficiency.
