This is a 33 gm re-arm kit for use with the automatic, water-activated, UML MK5i inflator used in the Spinlock Deckvest 5D 170 N (pre-2018) and the Deckvest DURO 170N, the Deckvest LITE and LITE+.
This sensor is water activated. It is not the Hammar hydrostatic model which is activated by water pressure at a certain depth. The kit includes the 33g CO2 cylinder and firing head. This re-arming kit is also suitable for other manufacturer's lifejackets which use the UML inflator system with a 150N/170N bladder. This re-arming kit is also suitable for other manufacturer's lifejackets which use the UML inflator system
Heavy on the technical side...
CO₂ lifejacket inflation systems are incredibly reliable but depend on the use of steel cylinders. Damp, salty, humid marine environments can quickly corrode CO₂ cylinders, causing them to rust if they are not cared for. Even a small build up of rust and corrosive electrolytic salts can quickly get to the point where the integrity of the cylinder is compromised.
To overcome this well known risk, Spinlock has developed a unique corrosion resistant coating (CRC™) that prolongs the life of their cylinders. The revolutionary coating has proved itself in salt environment testing compared to typical uncoated steel cylinders commonly used in inflatable lifejackets.
