Datrex Introduces Hydrostatic Release For Inflatable Life Rafts

Datrex, Inc., Miami, Fla., has introduced the U.S. Coast Guardapproved/ SOLAS 74/83 Hammar H20 two-year disposable hydrostatic release for commercial marine inflatable life rafts.

Datrex reports the new Hammar H20 release is safe, reliable, and through simplicity of design, offers a substantial cost savings.

A glass fiber-reinforced nylon housing holds a pressure chamber which activates a spring-loaded, ra- zor knife when the unit reaches a depth between 1.5 m to 4 m. As the knife is released it cuts through a rope sling in which the lashing of the life raft is attached thereby allowing the life raft to float free of its stowage set up while still being attached to the vessel by the activation line of the life raft and the weak link of the Hammar H20 release. As the life raft continues to float upward toward the surface, the activation line is drawn out until reaching the operating wire connection of the gas cylinder which then ignites the inflation system and the life raft breaks the weak link connection of the Hammar H20 as the vessel continues to sink. The Hammar H20 allows fully automatic operation of the inflatable life raft in the event that one cannot manually launch the life raft.

The Hammar H20 Hydrostatic Release is designed for a period of two years of service on board the vessel without any maintenance. Each release is marked with an expiration date and is easy to install.

Datrex offers a dealer and distributor program in the U.S. for the Hammar H20 release.
