The Det Cone is used for the safe testing of detonator circuit continuity. This customer led development is for specialist circumstances in which, once deployed, the detonator will be dangerous and expensive to retrieve if it is found to not have circuit continuity. The unit is robust, quick and simple to use. In the rare event that a detonator fires during such testing, the operator is safe, even if very close by. The Det Cone is one of our Blast Containment Systems.
The catalyst for this particular development was from the oil industry and seaborne platforms. Detonators are used with specialist explosive charges to open up the geology to free the flow of oil. The confines of such a well-head are not compatible with the usual best practice and safety distances for a potential detonator initiation. The depth of such wells means that it takes a long time for the charge to be put where needed and then to be retrieved again if the detonator does not have electrical continuity and won’t fire when needed.

A discussion at the DSEI defence show in London posed the question on the possibility of adapting our Detsafe technology to safely contain an array
We have recently completed the design phase for a novel blast/pressure containment vessel. This will allow the customer to perform research and proofing of their
