CU-LT user benefits:

Minimal impact on building space requirements thanks to the minimal distance CE certification and the compact damper and mechanics design
down to 25/50 mm vs. structure (floor/ceiling/adjacent wall) or 50 mm between dampers (instead of 75/200 mm standard CE).
Minimal pressure loss in the damper body and ventilation system
ultimately leading to lower system investments and energy consumption.
Minimal acoustic / noise impact.
Lowest standby power consumption in the market when using the ONE motor.
Easy installation and maintenance (compared to traditional UK type fire dampers).

CU-LT range:

Width x Height (mm) 200 x 100 to 800 x 600.
Tunnel casing (mm) 300 or 500.
