TiNi’s Subsea Ejector Release Mechanism (ERM) includes a Pressure Balanced and Oil Filled (PBOF) enclosure such that it can operate directly in Sea water at high pressure. It has been successfully used in many deep ocean applications to deploy critical instruments from various manned and unmanned submarines.
TiNi Subsea ERMs Offer the following advantages:
NEA (Non-Explosive Actuators) – As with all TiNi products, the ERM is non-pyrotechnic and field reset-able with a minimum qualified life of 50 cycles.
Rated to High Pressure – All Subsea ERMs 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 ERM 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 ERMs 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.
