About Smoke
 
Artificial smoke is produced by heating a chemical above its boiling point within
a heat exchanger. The chemical is then vaporised, and when the vapour exits
the heat exchanger and mixes with the relatively colder atmosphere that rapid condensation of the vapour takes place, resulting in a visible smoke (or technically, fog).

It is important that the vaporisation of the chemical within the heat exchanger is complete, otherwise the production of a 'wet' smoke, or a smoke with a very large particle size will result.

Conversely, it is important that the heat exchanger through which the chemical
is passed is not operating at too high a temperature, otherwise unpleasant and potentially hazardous pyrolysis products will be formed.

Depending on the type of chemical being vapourised, and the nature of that chemical it may be necessary to use an inert propellant gas as a “carrier” for the chemical as it is heated within the heat exchanger.

Our machined range of heat exchangers produce a smoke or fog effect with a particle size an order of magnitude less than conventional smoke systems, giving significant benefits in terms of smoke concentrations required to achieve obscuration targets, health and safety, flammability and settling velocities of the resulting fog.
