TiNi’s Subsea Pinpullers have been used in many oceanic projects. Typical applications include deployment of ballasts, buoys, cables, and other items from a wide array of AUVs. Much like our ERMs they include a Pressure Balanced and Oil Filled (PBOF) enclosure such that they can be used directly in sea water at high pressure.
TiNi Subsea Pinpullers Offer the following advantages:
NEA (Non-Explosive Actuators) – As with all TiNi products, the Pinpuller is non-pyrotechnic and field reset-able with a minimum qualified life of 50 cycles.
Rated to High Pressure – All Subsea Pinpullers incorporate a PBOF enclosure such that they can be used directly in sea water. All materials used have been selected to minimize corrosion and need for shipboard maintenance.
Field Reset-able and Reliable – The Pinpuller can be reset within seconds while still attached to the structure via a simple tool provided by TiNi Aerospace.
Redundant Firing Circuit – As with all TiNi Actuators a redundant SMA circuit is incorporated. This provides complete electrical redundancy as well as mechanical redundancy for the critical TiNi trigger element.
Fast Acting – All TiNi Pinpullers can be actuated with a standard pyro pulse of only 25 milliseconds or less.
Auto Shut-Off Switches – Simple Auto Shut Off Switches are incorporated into each ERM to protect the TiNi Trigger. This makes them very “user friendly” and operable from a wide range of current and voltages.
