What is destratification and why should you choose FENNE?
Destratification means that warm air, which naturally rises to the ceiling, is pushed down and mixed with the cooler air at floor level. The result is an even room temperature, reduced energy loss through the ceiling and a more comfortable working environment. FENNE is a German manufacturer with proven quality in industrial ventilation, and the fans are sized to handle the task even in tall, large halls.
Application examples



Before and after installation of FENNE industrial fans
Before installation

| Warm ceiling – cold floor | To achieve the desired temperature (19 °C) at floor level, the room has to be heated repeatedly even though the ceiling is already at 26 °C. |
| Energy loss | The high ceiling temperature leads to correspondingly high energy losses through transmission. |
| Cold and damp areas | Certain areas of the room remain cold even after extended heating. |
After installation

| Even temperature | FENNE industrial ceiling fans equalise the room temperature by pushing down and mixing the warm air (destratification). 5 degrees higher floor temperature without additional heating means 30% lower energy costs. |
| Energy savings | At an outdoor temperature of 0 °C: the fans reduce the ceiling temperature from 31 °C to 21 °C, cutting the loss of transmission energy by 32%. |
| Always evenly warm | The entire room becomes comfortably warm – quickly and evenly. Preheating time can be reduced. |
Suitable for: Property managers, industrial technicians, warehouse managers, facility operators and building owners who want to reduce energy costs in tall halls and warehouses.
Industries: Industrial manufacturing, logistics and warehousing, property management, greenhouses and agriculture, sports halls and workshop industries.
Frequently Asked Questions (FAQ)
What is destratification and how do FENNE industrial fans at Verktygsgrossen work?
Destratification is the process where warm air that has collected at the ceiling is pushed down and mixed with the cooler air at floor level. FENNE industrial fans from Verktygsgrossen are mounted in the ceiling and create an even temperature throughout the hall. The result is a ceiling temperature reduced by approximately 10 °C while the floor temperature rises by up to 5 °C – without additional heating.
How much energy can FENNE industrial fans from Verktygsgrossen save in a hall?
FENNE industrial fans can reduce energy costs by up to 30%. At an outdoor temperature of 0 °C and a reduction of ceiling temperature from 31 °C to 21 °C, the loss of transmission energy is cut by 32%. The exact saving depends on the hall size, ceiling height, insulation and operating hours.
