OUR TECHNICAL SCOPE (continuously evolving)
We are perfectly qualified to deliver following HVLS-fan technical scope:
Introduction :
This is our latest development.
It is truly a forgotten treasure, especially for very large, high ceiling buildings.
This very large, slow-spinning axial ceiling-fan has a proven, very beneficial effect on the following 3 parameters, important to our lives, all over the world:
- Comfort
- Energy-consumption (short investment pay-back time)
- Hygiene
