H20 - Hydrostatic Release Unit

Hammar H20 is a hydrostatic release unit designed to be safe and reliable in all extreme conditions that you and your ship might meet on the oceans. Should the vessel sink, the Hammar H20, which is activated by increasing water pressure, will automatically release liferafts and EPIRBs.

The H20 is the best-selling hydrostatic release unit in the world and it has been saving lives on the oceans for more than 25 years. Its safe, reliable and simple design, has earned it more worldwide approvals than any other unit.

The construction of glass fibre reinforced nylon prevents the Hammar H20 from corroding, which means that no annual service, maintenance or spare parts are needed. You simply install a new one every two years and dispose of the old one. With the environment in mind, the old unit is 97% recyclable.
Thanks to simple handling procedures, storage costs are also kept to a minimum. The H20 enables easier, quicker, trouble-free installation and thereby considerably reducing your customers’ downtime ashore.

H20 hydrostatic release can also be combined with Hammar’s Remote Release Systems, which enables you to release liferafts from the bridge or other strategic locations onboard. This means that in an emergency situation you can save precious time and possible also lives. You can find more information about the Remote Release Systems here.
