CONSTRUCTION CHARACTERISTICS
Circular, electronic or pneumatic, pressure-independent flow rate controller.
It consists of a galvanized steel casing (Class C leakage to EN 1751) and control damper (Class 4 blade leakage to EN 1751). Equipped with aluminum differential pressure measuring probes.
Duct connections are fitted with rubber gaskets.
TRN. series terminal units are designed to maintain a preset constant airflow rate for differential pressures ranging from 20 to 1000 Pa and ambient temperatures from 0 to 50°C.
Variants:
- TRN.I.25: version with a double-skin casing and 25mm thick insulation to reduce breakout noise;
- TRN.I.50: version with a double-skin casing and 50mm thick insulation to reduce breakout noise.
