Ship fire and gas damper HT

Fire and gas dampers prevent the spread of fire, smoke and gas between fire zones, where people must have the maximum amount of time to react to possible fire. The dampers are type-approved according to A0 (A60) or H0 (H120). The patented blade structure of the FDB2 dampers have special seals that are effective up to 300 °C and thermally activated graphite seals that expand when the heat rises to 150 °C in ductwork. These unique safety features ensure air tightness and low leakage to prevent fire, gas and smoke progression in a ductwork. Shut-off dampers Shut-off dampers shut off the airflow in ductwork where tightness, thermal insulation and reliability are important. The dampers meet international standards for rectangular and circular ducts. The leakage class is accordance with the EM1751 standards. Balancing dampers Balancing dampers adjust or control the air flow rates in ductwork where leakage does not have significant importance. Blast dampers Blast dampers protect ventilation systems against the effects of explosions. The dampers shield industrial facilities and related buildings against destructive blast forces. The dampers offer higher air flow capacity and increased level of safety as well as flexibility for design of duct systems. Non-return dampers / Pressure relief dampers Non-return dampers and pressure relief dampers are used in oil and gas applications to prevent backflow and relieve the pressure through ventilation ductwork. Air flow adjustment dampers PRA air flow adjustment dampers are manually adjustable measurement units for circular ducts. The dampers are used in duct systems to control the air flow.
