The EKA 350™ is our most popular device, with zero defect in more than ten years in service all around the world

Description

The EKA 350™ is a capacitor discharge (CD) blasting machine which presents the most reliable firing means available. Its small size means that it can fit into the palm of your hand.
The EKA 350SE is upgraded design to provide more energy and higher voltages.

Firing ability

A single EKA 350 device can fire up to 120 standard (2 Ω) elec­tric blasting caps (EBCs) in a single series on a 150 m reel of military communication wire (the equivalent of 0,6 mm copper wire), while EKA 350SE can fire more than 200 EBCs in two parralel series. A standard, fresh alkaline battery provides a minimum 1000 charging cycles.

Safety

EKA 350™ models have a built-in safety system that prevents the machine from firing if the blasting circuit is broken, or the desired voltage is not reached. It has a built-in Demolition Safety Light (DSL) to safely check the continuity of the initiators and the firing lines.
EKA 350™ provides a self-test feature that eliminates costly testing equipment and time consuming inspection procedures. The machine is operated by magnetic switches, which contain no mechanical parts, thus eliminating the chance of any mechanical failure.

Mechanical protection

The casing of the machine is extremely durable and is made from chromium nickel steel. All the other metal parts are galvanized in hard industrial gold, which make the whole casing environmentally inert, and give an extremely high level of mechanical protection. The electronic components are casted in a monolithic block using a special compound.

Serial Connections

In cases where energy provided by a single EKA 350™ or EKA 350SE™ device isn’t sufficient (like activating large number of EBCs, using EBCs with long Fe leg-wires or firing seismic detonators), two blasting machines can be connected together to multiply the energy output.

General purpose

Commercial or military

EKA 350 is used both for commercial purposes, as well by security and armed forces

De-mining programs

Humanitarian organizations and mine clearance agencies use our EKA 350 blasting machine in removal of land mines and unexploded ordnance (UXO) operations

Surface blasting

EKA 350 is often used in light quarrying applications, to initiate detonating cords or shock-tubes

Underground mining

EKA 350 is an ideal choice for underground metals mining

Construction blasting

EKA 350 is right choice for road-building and light tunneling applications. For more power, you can always serially connect 2 EKA 350 blasting machines.
