Electromagnetic door holders

Flexibility with the largest product range in the industry

Door holding magnets from Kendrion are used as locking devices of fire barriers (fire doors, fire gates, fire valves) to keep them in an open state. In this respect, the guidelines of the German Institute for Structural Engineering (Deutsches Institut für Bautechnik, DIBt) have to be observed.

They are also used for conventional doors, especially in shops and entrance areas, where they have to be kept open safely and reliably, with minimum power consumption and high holding force. The door is closed by pushing a circuit breaker to disconnect the power supply. For these applications, 230 Volt AC (mains voltage) models are available, which are easy to install and come with accessories.

Tested quality

When applied for fire-protection purposes central fire alarm systems resp. controlling smoke switches release the barriers by disconnecting the power supply if smoke is detected. Doors resp. barriers are automatically closed by means of door closers, thus preventing the spread of fire and smoke to the whole building. These applications are based on specific tests and approvals. As a leading manufacturer Kendrion offers a full product range in compliance with the guidelines!

Designs for ship-building and explosion protection

By its focus and market position Kendrion also offers variants for ATEX areas (EX) – tested by the Physical Technical Federal Institution (Physikalisch-Technische Bundesanstalt, PTB) – and for the maritime sector (shipbuilding and off-shore platforms) – tested by the “Germanischer Lloyd”.

Mounting options

The holding magnet is mounted to the wall, the floor, or the ceiling behind the door. Due to the diversity of types, almost any requirement profile can be fulfilled. An armature plate mounted to the door serves as the counterpart. Standard models, flexible angle settings, and spring-damped variants (for heavy doors) are available.

KENDRION has been manufacturing door holding magnets since the late 1960s and is considered as one of the inventors of this type of locking device. Over the years, our leading position has been established by continual innovation in design and technology. The door holders stand for quality, efficiency, and user-friendliness. Tested quality saves lives and is considered as the primary installation requirement.
