SINV is an extra-safe  non-electric initiating system based on shock tube and detonating cap technology.

SINV-P surface delay initiation device is designed for transmission delay with the initiating impulse delay in surface blasting and in gas and dust safe underground mines and pits.

SINV-S downhole delay initiation device is designed for in-hole delay initiating in surface blasting at the temperature of 40°C below zero to 50°C above zero, with exposure to high temperature up to 85°C above zero within 12 hours.

SINV-Sh blast-hole delay initiation device is designed for delay initiating of blast-hole and in-hole charges in underground pits and coal mines, where application of class II non-safety explosives is allowed, and also in surface blasting, except in-hole charges.

SINV-Start triggering initiation device is designed for initiating SINV or detonating cord blasting circuits  in surface blasting and in gas and dust safe underground mines and pits.
