About Smoke

Artificial smoke is produced by heating a smoke fluid chemical above its boiling point within a heat exchanger. The fluid is then vaporised, and it is 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 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.

Testimonials

Bekonscot - Managing Director

For several years we went through numerous smoke generators to simulate a "burning building", an important feature in our presentation.  Although the effect produced was good, the reliability, servicing and running costs of the system were always a headache, with smoke machines sometimes lasting a few weeks before they failed.

In June 2000, on recommendation, we contacted Concept Smoke Systems regarding the smoke installation.  A ViCount system was installed and commissioned later that year and has been operating without failure ever since!! Smoke chemical consumption has fallen dramatically, serviceability has been 100% and the effect is as impressive as ever.  Minimising issues relating to maintenance, and maximising reliability has given all of our visitors (some 200,000 per year) the benefit of seeing the smoke effect.

We wouldn't hesitate to recommend these systems to other users who need reliable and cost-effective smoke!
