The Global Defender significantly mitigates the effects of dispersal (Chemical, Biological, and Radiological) and Explosive threats up to 5 pounds. In addition to multiple explosive analyses, the system was evaluated by the US Department of Energy for Radiological Dispersal Device containment. The system fully contained 2 daily doses of Technetium-99 attached to a 1 pound binary explosive charge within a 20 feet radius as opposed to an unmitigated 1 daily dose contamination radius of 75 feet and the aerial dispersion of the agent.

Method of Operation

All systems use the patented foam enclosures. The enclosures, which are folded for easy storage and deployment, automatically unfold to cover the device as they are filled with foam. The enclosures are made from a synthetic material designed to expand and give way, as necessary, when the device is detonated. The expansion enables the system to suppress and contain the blast effect, fragmentation, and any dispersible agents that may be attached to the device. The enclosures are fabricated with a solid bottom to prevent the foam from contacting the device reducing the risk of inadvertent detonation and it allows the enclosure to be moved once it is filled without spilling the foam.

The systems are compatible with most tools available today including disrupters, counter-charges, and perforators among others. A deployed system provides operators at least four hours of mitigation before the foam begins to degrade. The thickness and density of the proprietary foam offers many benefits including extended time to address a mitigated device, suppression, containment of dispersible agents by capturing and containing the agent within its bubble structure suspending it for hours, and easier clean-up post blast since the foam remains intact. The foam is biodegradable allowing it to dissipate on its own with no required cleanup if it was not contaminated with any dispersible agent.

Test Results Data

Available in three standard and customizable configurations.

All portable systems are constructed with lightweight carbon steel vessels and aluminum frames yielding systems that are easily transported and maximum strength.  All pressure vessels are built to ASME standards.

  • 60 gallon Portable System: designed for a single application using the standard 6’ x 6’ enclosure.
  • Fixed Trailer Mounted System:  designed for larger explosive device (greater than 2 pound of high explosive) and for multiple applications.
  • Combination Trailer System:   includes the Portable and Trailer Mounted Systems providing maximum mitigation and flexibility.

Global Defender Portable System

Global Defender Portable SystemThe 60 gallon Portable System is designed to be transported and deployed from trailers, pickup trucks, vans, or aircraft. It is mounted on four all-terrain tires for high maneuverability over rough terrain. The system is completely self-contained and remotely operated with 100 feet of non-collapsible light-weight discharge hose mounted atop the system on a hose reel providing maximum stand-off range. With the enclosure in place, the system is activated by rotating a single handle. The system is powered from two nitrogen cylinders fit alongside the unit in flexible bottle racks. Once activated, the operator may retreat to a safer distance while the system automatically fills the enclosure and covers the device. The portable system will mitigate explosive devices containing up to 2 pounds of high explosive.

Global Defender Fixed Trailer Mounted System

Global Defender Trailer SystemThe 130 gallon Fixed Trailer System is designed to provide maximum suppression and containment capability. The system includes an enclosed cargo trailer containing a full complement of equipment necessary to operate the system including an electric hose reel, 150 feet of non-collapsible discharge hose, two Nitrogen cylinders, and a fixed fluid pumping system to transfer mitigation foam from 55-gallon drums into the system vessel and storage boxes. The Fixed Trailer System will fill the largest enclosure, 9 feet base by 5 feet tall, or fill two small enclosures, 6 feet base by 4 feet tall. The largest enclosure will mitigate and contain devices containing up to 5 pounds of high explosive.

Global Defender Combination Trailer System

Global Defender Combination SystemThe Global Defender Combination Trailer System combines the Portable System with the Fixed Trailer System providing operators with multiple options regardless of the circumstance. The Portable System is stowed within the trailer in a unique transport rack and is otherwise completely independent of the Trailer System. The Portable System can be removed from the trailer and positioned wherever necessary as required to address the situation. However, if circumstances dictate, the Fixed Trailer System can fill a much larger enclosure or can be used to cover multiple devices without requiring a system recharge.
