The HAMMAR HE-0221 H20E Hydrostatic Release Unit (HRU) is a safety device designed for use with compatible marine EPIRB float-free mounting brackets. In the event of vessel sinking, it automatically releases the EPIRB when submerged at the specified depth, allowing the beacon to float to the surface and transmit distress signals. The unit is designed for reliable operation in marine environments and must be replaced according to the manufacturer’s service-life and expiry-date requirements.
