Electro-Hydraulic TCP Firing Head

• Very compact design

• 400°F(204°C ) 30,000 psi (2,070 Bar) rated

• Requires specific series of pre programmed pressure cycles to function.

• Based on true TCP firing system technology rather than capacitors and electric detonators used in most other electronic firing heads.

• Can be run with another electro-hydraulic head, a pure hydraulic firing head, and a slickline or wireline deployed firing head for additional redundancy.

• Up to 14 weeks firing delay with auxiliary battery pack
