By slowly rotating at low rpm, our fans create an air flow whose dimensions, depending also on the
layout it encounters, can reach about 4 times their diameter, in all directions.
This ventilation system is used in large spaces such as production plants, logistics centers, sports
halls, department stores, where air conditioning systems are very expensive both as an initial
investment and in subsequent operating costs
The best option in these cases is Evel's HVLS ventilation system, with which the perceived
temperature is reduced from 2 °to 6 °C in the summer season, while in winter the mixing with
the warmer air in the ceiling increases by 4°to 6°C the temperature on the ground with a
consequent energy saving of about 30%. This improvement can be observed as indicated in the
chart "Thermal Comfort Diagram" (https://comfort.cbe.berkeley.edu/EN) created by the executive
for health and safety of the Berkeleyʼs University. The HVLS fan, working in destratification mode,
is ideal for large structures not equipped with the HVAC system, which reach high temperatures in
summer, cold temperature in winter with a high percentage of relative humidity (specially in
summer).
