PASSIVE DISPLACEMENT VENTILATION
TODAY'S AIR CONDITIONING SYSTEM
WHAT IT IS
Passive Displacement Ventilation (PDV) is an innovative fan-less air distribution system which makes use of a natural phenomena;
​
“hot air rises, cold air sinks"
WHY PDV
PDV System is a lean and clean system.
With PDV System, occupants can do away with the false ceiling and enjoy a voluminous space.
​
No ducts, no diffusers to hideaway.
Since there is no fan nor a motor, the PDV System is perfectly silent.
Without any draught, the occupants
experience a new level of thermal comfort and an acoustic standard unmatched by the conventional system.

HOW WE CAN HELP YOU
In tropical climates, the air distribution system consumes about 15% of total building’s energy use.
​
With the PDV system, buildings do not need any recirculation fans to distribute cooled air; i.e no AHUs, no FCUs, and thus save 15% of total energy bills.
