HQMAG 4000HS

All our electromagnets are checked in our factory at the end of the manufacturing process. The results, regarding the holding force, speak for themselves and are indisputable: In the 6000N category, the HQMAG 4000HS is the best “grade 6” product on the market. Don’t hesitate to ask us for test results and don’t forget to do the same with other big players on the market!

Like all our electromagnets, the HQMAG 4000HS complies with the requirements of EN 13637 chapter 7, the voluntary European standard on managing the systems for emergency exits. This norm requires that all the actual performances of the components of the locking parts of the system appear on a standardised label. This label is applied to all of our electromagnets.

The HQMAG electromagnets have been designed with specific, exceptionally high quality materials according to our unique know-how, and have never been defective for 35 years and counting. This dual requirement allows HQMAG to offer the only electromagnets intrinsically without remanence. Therefore, at HQMAG, no mechanical repeller, or electric repeller (Kick-off), with reliability that is uncertain over time is added. On standard electromagnets, these repellers are designed to prevent the electromagnet from “sticking” to its armature plate due to the unwanted retention of the magnetic field when access is to be released. Taking the risk of remanence (electromagnet with repeller) means accepting the possibility of catastrophic consequences in the event of an emergency evacuation. This is why electromagnets must, naturally, be without magnetic remanence!

HQMAG electromagnets benefit from certified corrosion-proof treatment and unmatched quality. They have passed the salt spray test (ISO 9227, ASTM B 117-90). Following this test, HQMAG electromagnets keep all their attributes and lose no more than 10%, on average, of their efficiency (compared to up to 70% for some of our competitors). These results prove the HQMAG products are resistant over time, unlike the infamous, planned obsolescence from which many technological products suffer.

Various accessories, designed for the installation of HQMAG electromagnets, are available both for push doors or pull doors as well as for doors made of wood, steel, aluminium, PVC, glass, and so on. Mounting the HQMAG 4000HS, with or without its accessories, is simplified thanks to an intuitive and dynamic assembly manual.
