EN 1634 UL 1784 Door Window Smoke Barrier Tester Smoke Sealing Leakage Test Machine Fire Control Test Equipment

The door and window smoke barrier testing equipment is a high-precision experimental device specifically designed to evaluate the ability of building doors, windows, and roller shutters to prevent smoke leakage during fires. By simulating pressure differentials and temperature conditions typical of fire scenarios, it assesses the product's "smoke-sealing performance," making it a critical testing instrument for ensuring building fire safety.

• Complies with the test methods and relevant performance requirements specified in EN 1634-3, UL 1784 and GB/T 41480-2022
• Operates under ambient temperature conditions (air temperature: 20±10°C) and medium-temperature conditions (air temperature: 200±20°C), conducting tests at atmospheric pressure without causing smoke stratification
• Test furnace allowable leakage rate ≤7 m³/h
• Operating conditions: temperature ≤260°C, pressure ≤55 Pa
• Protection rating: IP65
• Temperature/flow output: Linear 4-20 mA signal output connectable to PLC for data recording
• Measurement accuracy: Flow rate of 55 m³/h with precision of ±1 m³/h
