Sound-damped volumetric flow controller PIANO

Domenii de utilizare:

For use in supply and return air systems, for duct connection to DIN EN 1505, with integrated volumetric flow controller for use in constant or variable volumetric flow, room or duct pressure regulation.

Funcţionare

The shorter design compared to conventional pressure-relief boxes makes installation easier in confined spaces, and the low overall height saves space. The smaller dimensions greatly simplify installation handling.
The sound attenuated volume flow controller type PIANO in rectangular design can be connected to rectangular ducts to DIN EN 1505 or to spiral ducts to DIN EN 1506 with a transition piece. This means that the sound attenuated volume flow controller type PIANO can be used variably in the event of on-site modifications.
The integrated, flow-optimised shut-off profile can be opened completely so that a free flow cross-section of 100% can be achieved. This largest possible free cross-section reduces pressure losses and minimises flow noise. Due to the optimised aerodynamic flow, no inlet and outlet sections need to be planned!
This means that the silenced volume flow controller type PIANO can also be used in very confined spaces. The low pressure losses also reduce the ongoing operating costs of the air conditioning system. The silenced volume flow controller type PIANO can already be used with a static pressure difference of 50 Pa, i.e. the duct network and the fan can be designed for low air velocities and the PIANO can be used in low-pressure systems.
