  • Breakable glass bulb fire detection link, miniature type

    Patented mechanical system of fire detection by liquid filled glass bulb breaking. In case of fire, when the temperature reaches the liquid boiling temperature, it causes the explosion of the glass bulb, which releases the mechanism

  • Copper fusible links with eutectic alloys, for medium loads

    These fusible links have a medium response time, between 3 minutes 25 seconds and 3 minutes 30 seconds, for a temperature rise rate of 20°C/min from 25°C, and their thickness of metal is thicker than brass models to gives them sufficient strength for their use in multiplied mechanisms supporting a maximum stress of 300DaN. The…

  • Eutectic alloys fusible links for medium loads

    These fusible links have a medium response time, between 3 minutes and 3 minutes 10 seconds, for a temperature rise rate of 20°C/min from 25°C and their thickness of metal gives them sufficient strength for their use in multiplied mechanisms supporting a maximum load of 300DaN. The holes have a lip to improve their resistance…

  • Eutectic alloys fusible links, for direct handling of heavy loads

    These fusible links have a response time near the highest limit requested by standard (whose threshold is 4 minutes), between 3 minutes 30 seconds and 3 minutes 50 seconds, for a temperature rise rate of 20°C/min from 25°C. Their 1.5mm metal thickness and their soldering surface make it possible to withstand directly and without multiplying…

  • Fast triggering eutectic alloys fusible links, brass or copper

    Made of thin metal, these fusible links have the shortest response time, between 2 minutes 50 seconds and 3 minutes, for a temperature rise rate of 20°C/min from 25°C, but the fineness of the metal limits their mechanical strength.

  • High load breakable glass bulb heat responsive link

    Patented mechanical system of fire detection by liquid filled glass bulb breaking. In case of fire, when the temperature reaches the liquid boiling temperature, it causes the explosion of the glass bulb, which releases the mechanism. This self-powered mechanism does  not require  power  supply such as electricity or compressed  air. It i  can open smoke…

  • Miniature eutectic alloy fusible links for large or very large series applications

    Manufactured in a fully automated way, these fire detection fuses are particularly economical for domestic applications in mechanical ventilation, extractor hoods. They are also externally coated with an alloy protecting them from corrosion.

  • Multiplied action mechanisms for eutectic fusible links, for application in smoke outlets

    Made of 3mm thick galvanized steel, these reduction mechanisms are compatible with most fusible links available on the market. Their high coefficient of reduction enables them to be used with links with a small welding area. Indeed, the traction on the fusible links is only 15% of that applied to the mechanism. The annual replacement…

  • Multiplied action mechanisms with thermal glass bulbs, for application in smoke outlets

    Made of 3mm thick galvanized steel, these reduction mechanisms are compatible with 20x5mm thermal glass bulbs. Their huge multiplying coefficient reduces the force applied to the thermal glass bulb to only 15% of that applied to the mechanism. The replacement of the glass bulb is simple and can be done without special tools. They withstand…

  • Thermal actuators with pulling action, for fire dampers, operated by eutectic fusible link

    These mechanical thermal actuators are intended to close the fire dampers used on the ventilation ducts. Their large operating force unlocks the spring actuating the damper. Requiring no power supply, these devices are particularly simple and reliable. They are mandatory for all fire dampers to meet the NF-S 61.937 standard.

  • Thermal actuators with pulling action, for fire dampers, operated by thermal bulb

    These mechanical thermal actuators are intended to close the fire dampers used on the ventilation ducts. Their large operating force unlocks the spring actuating the damper. Requiring no power supply, these devices are particularly simple and reliable. They are mandatory for all fire dampers to meet the NF-S 61.937 standard. Since thermal bulbs are not…

  • Thermal actuators with pushing action, for fire dampers, operated by eutectic fusible link

    These mechanical thermal actuators are intended to close the fire dampers used on the ventilation ducts. Their large operating force unlocks the spring actuating the damper. Requiring no power supply, these devices are particularly simple and reliable. They are mandatory for all fire dampers to meet the NF-S 61.937 standard.
