Key Advantages
Why TORDRIX FlowLine?
FlowLine combines precision-engineered louvre blades with robust steel construction to deliver reliable ventilation and access control in technical infrastructure spaces.
Optimized Airflow Design
Precision-angled louvre blades deliver up to 50% free area, ensuring consistent natural or forced ventilation across equipment rooms.
Heavy-Duty Steel Frame
Reinforced galvanized steel frame and louvre construction provides structural durability in high-vibration and heavy-use environments.
Fire-Rated Options Available
Optional fire-rated louvre door configurations designed for plant rooms requiring fire compartmentalization, complied with NBC provisions.
Multiple Blade Configurations
Available with fixed or adjustable louvre blades at 30° and 45° angles to match specific ventilation and rain ingress requirements.
Corrosion-Resistant Finish
Powder-coated galvanized steel surfaces resist corrosion from humidity, chemical exposure, and harsh plant room conditions.
Acoustic Louvre Options
Acoustic louvre configurations with infill material reduce noise transmission from generator rooms and mechanical plant areas.
Fast Installation System
Pre-assembled frame and louvre modules reduce on-site installation time and ensure accurate integration with wall openings.
