EDRCS THERM - EDRCS-PQR THERM Variable geometry thermostatic diffusers

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 individually adjustable 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.
