DGV SERIES DGV-T CIRCULAR DIFFUSER WITH THERMOSTATIC VARIABLE GEOMETRY Model DGV-T. Model DGV-TP. Variable geometry diffuser with thermostatic actuator. Difusor de geometría variable con actuador termostático. Placa cuadrada. Variable geometry diffuser with thermostatic actuator. Square plate. The DGV-T diffuser is characterised by the automatic regulation of its blades by means of a thermostatic actuator, due to the thermal memory effect of the Nickel-Titanium alloy. The regulation of the angle of deflection is very simple and intuitive by means of mechanical stops assisted by a colour scale....

Legend: Q = Flow rate Ak = Effective area of the diffuser neck in m² Hm = Minimum - maximum recommended installation height in m. B(min) = Minimum recommended distance between diffusers in m. Vk = Effective velocity at diffuser face in m/s. X = Reach in m. for final velocity 0,25 m/s Pt = Pressure drop in Pa LwA = Sound power level in dB(A) SERIES DGV - DGV-T SELECTION TABLE 2000 555,6 VARIABLE GEOMETRY DIFFUSERS * Values for isothermal supply closure without coanda effect. ** Values with 45º angle of inclination of fins.
