Beethoven MK 19 Exploder. Non battery / hand generator
Manufactured in a robust ‘Noryl’ moulded case. They are completely water and dust proof. A unique feature of the case is the inclusion of sliding billet terminals. This feature makes cable connection especially easy and prevents the cables from damage.
Automatic firing is achieved by a two handed operation of depressing the fire button whilst turning the generator handle. If the fire button is released the charge on the capacitor is safely dissipated.
Manual firing is achieved by holding the charge button whilst a hand operated generator charges a capacitor to the required voltage, when the neon indicator lights the exploder is fired by pressing the firing button. The charge on the capacitor will be safely dissipated if the charge button is released. The exploder will only fire if the neon light is fully on.
Approved models are approved for use in underground mines where use of “Permitted” explosives is required. Non-approved for use in all surface applications.
The table below describes the recommended circuit resistance which can be successfully fired with the Arbra Beethoven range of exploders. These figures assume bottom limits for the exploder and detonator manufacturers published figures for 99% firing success. Download PDF Spec sheet
