HAMMAR H20 HRU - SOLAS-Compliant Hydrostatic Release Unit - H20 Standard Model UKCA/EC Certified for Liferafts - HR-0100
HAMMAR H20 Hydrostatic Release Unit - HAMMAR H20 HRU - SOLAS-Approved Hydrostatic Release System - HR-0100 H20 Standard Version UKCA/EC Certified for Liferafts (6 to 150 People)
The Hammar H20 Hydrostatic Release Unit ensures reliable deployment of liferafts and EPIRBs in extreme conditions. Activating automatically at depths of 1.5 - 4.0 metres (SOLAS), it cuts the securing rope to allow the liferaft to float free (6-150 people). The HRU functions in temperatures from -30°C to +65°C and is favored by over 50% of global EPIRB manufacturers. Made from corrosion-resistant glass fiber-reinforced nylon, the Hammar H20 requires no annual maintenance—just replace the unit and bolt every 2 years. Environmentally friendly, it is 97% recyclable. Certified to SOLAS and various IMO standards, it has a 5-year shelf life when stored properly.
Key Features & Equipment Benefits:
- Safe & Reliable in Extreme Conditions: Designed to perform reliably in harsh marine environments; activates automatically under increasing water pressure to release liferafts and EPIRBs if the vessel sinks.
- Global Best-Seller: The Hammar H20 is the world’s most widely used hydrostatic release unit, known for its safety, reliability, and simple design, with over 25 years of proven performance.
- Maintenance-Free: Constructed from glass fiber-reinforced nylon to prevent corrosion, requiring no annual service or spare parts. Replace every 2 years, and the old unit is 97% recyclable.
