A Hammar hydrostatic release unit (HRU), like the Hammar H20, uses water pressure to automatically release a life raft or Emergency Position Indicating Radio Beacon (EPIRB) when a vessel sinks. It's designed to activate at a depth of 1.5 to 4 meters, cutting a securing rope and allowing the raft or beacon to float free and inflate.
Here's a more detailed breakdown:
Mechanism:
The HRU contains a spring-loaded blade held in place by a pin. The pin is connected to a membrane. When the water pressure reaches a certain depth (1.5-4 meters), it acts on the membrane, pulling the pin out of the blade's notch.
