With all the benefits of Halon and none of its environmental disadvantages, i2 from Hygood is the solution of choice where the call is for a clean fire suppression agent that’s non-toxic, non-corrosive, odourless and leaves no residue.

One of the crucial features of i2 is that, in environmental terms, it brings nothing new – and thus potentially damaging – to the atmosphere. It comprises a pure 50:50 mixture of two gases which occur naturally, Argon and Nitrogen. What’s more, because the blended component gases have a density similar to that of air, the mixture is able to retain its concentration in the risk area for far longer than Halon.

In today’s sensitive politcal environment, i2 meets important criteria, with no global warming or ozone depleting potential. Because it’s inert, it forms no breakdown products minimising the risk of consequential damage.

It is, in short, a very friendly alternative to Halon 1301, being safe to use in occupied areas and with the benefit of having been recognised by regulatory bodies around the world.

Effective and Safe Gaseous Fire Protection from Hygood

Efficient and Rapid: Hygood’s i2 system is effective against virtually all combustible materials and flammable liquid fires and is an ideal choice where an environmentally acceptable agent is mandatory. In a closed space, tests and experience confirm that almost every fire will be extinguished quickly but effectively.

Delivering Results: i2 extinguishes fires by reducing the ambient concentration level of oxygen in the risk area to between 10 and 14 per cent. Because oxygen concentrations below 14 per cent are insuffcient to support combustion, fire is extinguished. However, oxygen concentrations at these levels are enough to support life for a short period, making i2 safe to use in occupied spaces. As a result, typical applications include manned areas such as computer centres and telecommunications installations. In these and other instances, i2 is stored as a gas in high pressure cylinders filled at a pressure of 200 Bar.

Future Perfect: Practically everything we do has some impact on the world about us, but Hygood’s i2 is quite different. Its constituent gases already circulate freely in the atmosphere, so this friendly fire protection solution neither adds to the environment, nor takes anything away. Containing no bromine or chlorine, i2 has zero ozone depletion potential. And with a global warming index of 0, this agent has no impact of any kind on climate change. Furthermore, it delivers no toxins or odours, leaves no residue and is non-corrosive. In a world where long-term corporate responsibility has to be taken more seriously than ever before, Hygood’s i2 is a wise choice.
