Twenty80 Passive Displacement Ventilation (PDV) System is an innovative air distribution system that provides a cost effective way to cool your buildings. A key feature of the PDV system is the absence of fan. The system relies on the natural convection of heat transfer to deliver the chilled air to the end user, providing a comfortable indoor environment.
 

• Due to the low velocity of the supply air, undesirable draft or unevencoldness is eliminated, leading to greater occupant comfort.
• Acoustics wise, un-matched by conventional systems with mechanical fans.
• Substantial reduction in maintenance costs due to absence of mechanical fans.
• Less structural consideration due to reduced ductwork.
• MyHijau certified

This zero energy airside cooling system or passive displacement ventilation (PDV) system presents an innovative technology for building owner to cool their uilding at substantially reduced electricity cost without the hefty re-construction and capital costs for ducting, diffusers and electrical cables. It also allows building owner to integrate the cooling system easily into the building interior design.
