Hydrostatic Release Unit
McMurdo Hydrostatic Release for Catagory 1 EPIRB ‘BreaktHRU’ – the Hydrostatic Release Unit (HRU) Kit from McMurdo. Smaller that other HRUs currently available, BreaktHRU is unique in its use of a small pyrotechnic charge, which is used to enable EPIRBs to automatically float free.
- Classified non-hazardous
- Complies with the latest SOLAS and IMO resolutions
- Fits the footprint of existing HRUs
- Service life of two years
Using technology developed exclusively by McMurdo, the pyrotechnic charge is used to activate the HRU when it is submerged in water < 13 feet. Once activated the EPIRB is automatically released - it's as simple as that!
