About Smoke

It is important that the vaporisation of the fluid 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 smoke fluid 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 smoke fluid being vaporised it may be necessary to use an inert propellant gas as a “carrier” for the fluid as it is heated within the heat exchanger.

Concept's 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.
