Hammar H20E Hydrostatic Release Unit (HRU) for EPIRB

Share this product

The Hammar H20E Hydrostatic Release Valve is widely used by Emergency Position-Indicating Radio Beacons (EPIRBs). Trusted by 90% of global EPIRB manufacturers, it ensures reliable float-free deployment. In the event of a ship sinking, the H20E, triggered by water pressure, automatically releases the EPIRB. Once on the surface, the EPIRB transmits identification and location signals to satellites. Replacing traditional ropes, it utilizes an innovative plastic bolt designed to break during activation.
