H20 ERU - Electric Remote Unit (RED/YELLOW) - H20 for MES - Electric / Water Activated Electronic Release Unit - EC Approved Electronic Release Unit - HM-0405

The Hammar H20/ERU is a water-activated electric release unit designed for marine evacuation systems. Compact at just 0.3kg, it features a release depth of 1.5–4.0 metres and includes a durable white rope sling with a minimum breaking strength of 15 kN. EC-approved and supplied without a weak link, this ERU integrates with Hammar’s Electronic Remote Release Systems (ERRS). These remote systems use a control unit to send an electrical signal that activates one or multiple H20 ERUs at the push of a button. With no limit on distance between control and release points, input sensors such as water or list angle detectors can also be added. Ideal for large-scale systems with multiple release points or installations over 50 metres in length.

Key Features & Equipment Benefits:
