The Hammar H20 Blue Top Six-metre Deep Release Hydrostatic Release Unit (HRU) was initially designed for Royal Navy liferafts and is also used on marine evacuation system rafts which are fitted to high-speed craft. Activated by water pressure, the Hammar H20 Blue Top HRU will ensure that a liferaft floats free from a stricken vessel as its operation is triggered at a release depth of approximately six metres.
