GREEN90 – the lithium-free 90 days Underwater Locator Beacon

GREEN90 is the first worldwide lithium-free Underwater Locator Beacon (ULB). The alkaline manganese cell in GREEN90 is as reliable in performance as any lithium cell. It convinces with its enormous safety advantages of this type of battery. The strict guidelines for the installation and transport of lithium batteries are irrelevant for airlines using the GREEN90. They benefit from a greatly reduced handling effort – compared to the use of lithium ULBs.

GREEN90 has TSO/ETSO approval and is not subject to FAA SC3 and SC5, EASA CRI, RTCA-DO227A, TSO-C142b.

The GREEN90 minimum performance standards:

• Compact, lightweight and easy to service
• Frequency 37.5kHz +/-1kHz
• Minimum operating life 90 days
• Detectable in deep sea down to more than 20,000ft (6,096m)
