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 spring which vary its length according to the temperature of the air supplied to the diffuser, 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 cooling.
Characteristics
Material: aluminium structure with steel blades;
Finish: painted white RAL 9010.
Use
Diffusers suitable for heating and cooling in large rooms requiring and environments with minimum installation high 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.
