The Mathematics of Monitoring Gaseous Extinguishing Systems & Room Integrity

Applying Mathematics

The fire industry calling is a noble one. It is uses scientific principles to enable its very existence. The fire industry, however, calculates fire engineering designs based on formulas that its technicians have no way of understanding or verifying are accurate. The industry needs a Resident Mathematician to ensure that the formulas they use are correct. Fire engineers do not always understand the physical properties of the clean agents they use. Some do not wholly appreciate the impact of temperature on the state of an agent or its pressures. Novec 1230 for instance is an organic compound which deteriorates quickly to a point of non-effectiveness if poorly handled and stored. These problems and many more can be solved in the fire industry by the application of fundamental scientific and engineering principles. But they can only be proved by the application of the mathematics of them. Coltraco are at the vanguard of this in the fire industry.

Clean Agents

Are pressurised liquefied gases or non-liquefied gases that are pressurised on actuation. CO2 is permanently under 720 psi or 49 bar of pressure ie nearly 50 times atmospheric pressure (by comparison a cup of water at sea level exists at 1 bar or 14.5 psi). Its state changes under increased temperatures to one that is neither a liquid nor a gas. Gases under pressure are often effectively considered by the industry as single and passive cylinder columns of solid material from the perspective of their monitoring following installation. Whereas being under pressure and constantly changing under temperature they should be considered as active and dynamic systems requiring constant monitoring. These are not passive systems therefore; they are dynamic ones, and all dynamic systems under pressure need constant monitoring.  

We achieve this

By our ability to establish the liquid contents of liquefied clean agents – through UL-approved Portalevel MAX and the constant monitoring system, Permalevel Multiplex. Once we do this we can establish their weight and mass – through Portasteele Calculator (the world’s first product capable of this). If we can monitor their pressure too then we can monitor both the pressure of the gas above the liquefied agent such as in Novec 1230 and the pressure of non-liquefied gases such as Inergen or Nitrogen.
