Maxfire igniters

The Igniter

Maxfire is the first ever 1.4S pyrotechnic initiation system with timing capability. It is also the foremost electric system providing optimal initiation of propellant cartridges together with sequential timing and delay capacity. This initiation feature has previously only been possible with conventional explosives. Delay precision is equal to or more accurate than traditional detonator systems.

Benefits and features

World class pyrotechnical timing.
The Royex Generation II "Maxfire" Igniter features a highly accurate delay element encased in each igniter. Therefore it is possible to delay individual holes, or sets of holes, and thereby initiate the Royex propellant cartridges in a pre-determined sequence. Numerous delay sequences are available allowing the coordinated blasting of complete panels and development ends. No other system in the world is capable of this versatility.

Initiation heat and pressure is essential for the performance of non-detonating cartridges. The Maxfire initiation capability is the most powerful available on the global market today and this feature enhances the reliability and efficiency of the Royex cartridge making the Royex Generation II the most powerful deflagrating cartridge available worldwide.

Easy to connect.
Maxfire igniters are supplied with a butterfly screw fitting that smoothly connects with the Royex igniter plug*. The connection is secure and waterproof, ensuring that the igniter – cartridge connection is firmly in place during the loading and stemming operation.

Flexible and modular.
The electric Maxfire comes in two cable lengths as standard and with 8 delay times*
