Large Savings with Industrial Ceiling Fans
Systemair's Plant, Lithuania
In Systemair’s plant in Lithuania, the installation of ceiling fans has ensured that energy costs are kept down while creating a comfortable working environment for the employees. Energy efficiency can seem expensive, but this project shows that it is possible to reduce your heating costs through a relatively small investment cost. Depending on the energy price, the savings can range from €19 900 – €80 000 per year.
Improved working environment
During the winter months, the ceiling fans raise the temperature near the floor by 2–3ºC, improving the work environment for the employees.
Lower energy costs
Thanks to energy-efficient heating combined with ceiling fans, energy costs are lower and the work environment has improved.
Benefits of industrial ceiling fans
The ceiling fans force warm air downwards into the occupied zone, evening out the temperature difference between the ceiling and floor.

Ceiling Fans Can Reduce Costs by up to 30%
As energy prices increase and the climate goals place higher demands on energy efficiency, many companies are reviewing their heating systems. A problem in large premises with high ceilings is that the warm air will rise to the ceiling and cause heat losses. This can result in high temperature gradients and consequently increased energy usage.
With the use of ceiling fans, the hot air can instead be pushed down again and equalize the temperature in the room. In many cases, heating costs can be reduced by up to 30%.

Significantly Reduced Energy Costs and Improved Working Environment
Systemair is a leading ventilation company with operations in 49 countries around the world manufacturing and marketing high-quality ventilation products. The Group's main factory and logistics centre for smaller housing units is located in Ukmerge, Lithuania. The building’s total volume is 15,500 m2, divided into manufacturing, warehouse and offices.
The plant is heated by SWH fan heaters with air curtains installed over all doors to the exterior. To improve the working environment for employees and save energy, 95 ICF ceiling fans were installed. The ceiling fans force warm air downwards into the occupied zone, evening out the temperature difference between the ceiling and floor. Thanks to energy-efficient heating combined with ceiling fans, energy costs are lower and the work environment has improved.
We are very pleased with the installation. During the winter months, the ceiling fans raise the temperature near the floor by 2–3ºC.
