Ki Elements floating suits

We have received some feedback that Ki-Vest blows up just on one page or blows up late. Our answer has been that there is a difference if Ki-Vest is blown up on land (dry) or in water (wet).

Only now have we discovered that the difference is not in dry vs wet but in manual vs automatic blowdown.
In the black sleeve that is located on the trigger, there is a stamp loaded with a steel spring. In contact with water (= automatic inflation), the spring and piston presses a conical spike with great force against the gas cylinder. There will be a large opening in the cylinder so that the gas can flow out and expand freely.

When pulling the trigger cord (= manual inflation) or when the cord is jammed and unintentionally triggered, it may easily happen that the force is not large enough for the pin to perforate the gas cylinder completely. The gas flows out through a smaller opening which leads to
• Slower and weaker gas expansion
• ice in the trigger and lung (white CO2 spots in the lung = frozen CO2 that eventually becomes gas)
When blowing up manually it is important to pull the strap fast and fast.

The above can be seen in a short video here

Gas leakage when inflated
It is a known problem for all manufacturers of life jackets that gas cylinders can loosen. A loose cylinder can lead to gas leakage and thus insufficient inflation.

Ki Elements has solved this problem with Ki-Lock, which prevents gas cylinders from loosening. This is confirmed by customers who have installed Ki-Lock. The user and employer may then disregard routines for regular check of gas cylinders.

We strongly recommend that Ki-Vest and Ki-Suit purchased before April 2018 be upgraded with Ki-Lock. From April, Ki-Lock has been introduced as standard for all Ki Elements products.
It is important that the employer put in place measures to ensure that this is completed.
