Smart airflow control — built to seal under fire, tested to protect lives.

At Hypery International Ltd., we provide fully certified automatic fire and smoke damper systems designed to protect critical HVAC pathways during fire emergencies. These systems are engineered to close automatically when smoke or heat is detected, thereby preventing the spread of flame, smoke, and toxic gases through air ducts and ventilation lines.

Our dampers are:

• Thermally responsive and motorized, with fusible links or actuators that trigger immediate closure under specified fire conditions

• UL-listed and tested to meet international performance codes for both fire integrity and air leakage prevention

• Available in multiple configurations including rectangular, round, single-blade, or multi-blade designs based on duct type and air pressure conditions

We install dampers in:

• Air handling units (AHU) and ventilation ducts of commercial, RMG, and industrial buildings

• Mechanical floors, risers, shafts, and transfer plenums

• Stair pressurization systems, lift lobbies, and basement exhaust systems

Each system is supported with:

• Integrated control connections to fire alarm panels and smoke detection systems

• Testing and commissioning with full wiring diagrams, datasheets, and compliance certifications

• On-site support during RSC, Nirapon, and Bureau Veritas inspections, including engineering justification where required

With Hypery’s damper solutions, your building’s HVAC system transforms into a fire containment asset — responding instantly, sealing precisely, and safeguarding every zone behind the ceiling line.
