The Hydrostatic Release Unit from Sweden
is found life rafts and EPIRBs of all sizes and on all types of ships around the world. The new Hydrostatic Release Unit, with the same name as its predecessor H20, has been introduced.
The H20 is designed for easier installation. It has a 3-step coupling device that eliminates the risk of incorrect installation. The Weak Linkä of Hammar is now integrated into a new black thimble. This gives smaller tolerances in the Weak Linkä system (breaking strength 2,2 +/- 0,4 kN) as well as a stronger lower thimble construction.
For the end user, the new design will be noticed in first place by the clear and easy-to-understand installation. The thimble is, for instance, clearly marked with “DECK” to avoid any misunderstanding and possible upside-down installation. Each unit is supplied with multilingual installation manual and instructive self-adhesive label for the liferaft container.
As its predecessor, the H20 needs no service or maintenance for two years and has no corrosive parts inside.
The new and old H20 are 100 percent compatible, so that next time the Hammar Hydrostatic Release Unit is due for replacement, the new H20 can be used instead.
