Description
All-in-One is installed internally and consists of a CO2 tank, water sensor and buoyancy bags combined into a single unit, making it well suited for tight spaces. The system is available in two sizes, 500 and 300, providing 275 and 165 kg of buoyancy per unit respectively, and automatically activates in the event of excessive flooding. The buoyancy bags inflate in less than 60 seconds, helping keep the vessel afloat and stable when it matters most.
Designed and manufactured in Norway
Antisink is manufactured in Norway and meets all required approvals, with quality ensured at every stage of production.
Certified and robust
All Antisink products are CE certified and comply with relevant international maritime safety standards. They are compact, impact resistant, waterproof and flame retardant, and can also be manually activated if required.
With a focus on the environment
All components are reusable and recyclable. If an Antisink system is deployed, it only needs to be repacked before it can be used again. The only component that must be replaced is the CO2 trigger, while the CO2 cylinder can be refilled.
Antisink can easily be installed and repacked by the user by following the installation instructions. If in doubt, we recommend contacting your boat dealer for assistance.
All-in-One is a system that is easy to install and requires no external connections. Simply install the correct number and size of units based on the vessel’s total weight. The units are glued directly onto the vessel and are ready for use after 24 to 36 hours, depending on the ambient temperature during installation.
All buoyancy bags are equipped with an overpressure relief valve to prevent rupture if compressed. Each bag is filled to approximately 80 percent capacity, allowing it to adapt to its surroundings. There is flexibility of approximately ±10 percent in the inflated volume if the unit is installed in a compartment that does not exactly match the inflated dimensions.
Everything required for installation is included, as well as installation instructions.
General information for All-in-One
Trigger: UML Pro Sensor Elite with cellulose
CO2 cylinder: 300 g / 500 g – Welz GmbH
Overpressure valve: Halkey-Roberts
Note: Required buoyancy is generally calculated at approximately 30% of the vessel’s total weight for fiberglass boats. For an increased safety margin, we recommend sizing the system to approximately 40%. Other materials and constructions may require different buoyancy levels.
