Hammar H20 Hydrostatic Release Unit for Liferaft

SKU: HAMMAR HR-0102 Category: Tags:

The Hammar H20 is a hydrostatic release unit designed to fit liferafts of all shapes and sizes. It is made of glass fiber reinforced nylon, which prevents it from corroding. The HRU needs no annual service, maintenance or spare parts. You simply install a new one every two years and dispose of the old one.



The white strong rope of the HRU is secured to the deck or liferaft cradle and attached to the raft with a slip hook. If the ship sinks, the water pressure will, within 4 meters, activate the sharp knife, which cuts the rope and the liferaft will float free. As the ship sinks, the liferaft painter line will be stretched and the liferafts start to inflate.
