Hammar H20E Hydrostatic Release (HRU) for EPIRB

This standard H20E HRU model is USCG/EC approved. The Hammar H20 is the most reliable hydrostatic release unit on the market and is used by most leading Emergency Position Indicating Radio Beacons (EPIRB) manufactures. 

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.

This product is a full set (HE-0221), and includes:
– 1 x H20E HRU (HE-0102 / HE-0100*)
– 1 x Standard plastic bolt** with 2 washers (HE-0021)
– 1 x Stainless steel nut (HE-0045)

*there is mutual recognition between EC and USCG, so there is no difference between these 2 models
**other bolts are available on demand, depending on the EPIRB model used
