Hammar H20 E HRU For EPIRBs

The Hammar H20 is widely used for Emergency Position Indicating Radio Beacons (EPIRB). 50% of the world’s EPIRB manufacturers are using the Hammar H20 for the free float function. Should the vessel sink, the Hammar H20, which is activated by increasing water pressure, automatically release the EPIRB. On reaching the surface the EPIRB starts to emit a signal of identification and position to a satellite. Instead of the rope sling a specially developed plastic bolt secures the radio beacon and will be cut when the unit is activated.

**Important** 
Use only manufacturer approved replacement bolt (rod). The bolt should always be changed together with the release unit every two years. The Hammar H20 is made of glass fiber reinforced nylon, which means that it will not rust. The Hammar H20 needs no annual service, maintenance or spare parts. You simply install a new one every two years and dispose of the old one. Keeping the environment in mind, the old unit is 97% recyclable.
