We are very pleased
with the installation. During
the winter half of the year,
the ceiling fans raise the
temperature close to the
floor by 2 - 3 ºC.
Mindaugas Martišius
Managing Director, Systemair LT.
Warm air is lighter than cold air and therefore rises. Consequently, in
premises with high ceilings a cushion of warm air easily forms up under the
ceiling. This overheated air results in large and unnecessary energy losses.
In Systemair’s plant in Lithuania, the installation of ceiling fans has ensured
that energy costs are kept down while creating a comfortable working envi-
ronment for the employees.

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.
Without ceiling fans:
Temperature gradient: 2.5 °C/m
Total energy requirement: 1,246
MWh/year
Annual cost: SEK 1,246,000
With ceiling fans:
0.25 °C/m
1,029 MWh/year
*(including ceiling fans)
SEK1,029,000
Savings: > SEK 200,000/year
Payback period less than 1 year
