Description

Variable geometry diffusers with thermostatic actuator and equaliser.
The diffuser blades are adjusted automatically, without the need for a power supply, by means of a thermostatic actuator consisting of special shape memory nickel-titanium materials which vary their length according to the temperature of the air supplied to the diffuser, thus opening and closing the blades.

The blades provide the air with a helical movement and, at the same time, provide the direction of the air throw.

On the neck of the diffuser there is a graduated scale indicating the angle of the blade during heating or conditioning.

Characteristics

Material: aluminium structure with steel blades
Finish: painted white RAL 9010.

Use

Diffusers suitable for heating and cooling large rooms requiring a high installation height and in any case not less than 3.5 metres.

For both duct and ceiling installation.

Models

-EDRCS THERM: Variable geometry thermostatic diffusers with equaliser;
-EDRCS-PQR THERM: Variable geometry thermostatic diffusers with equaliser on square panel 595x595 mm.

On request

EDRCS THERM-PQR diffusers can be supplied without equaliser.
