The Concept SDTS is based on the best selling ViCount Hi temperature smoke system.

Unlike conventional water based smokes, the smoke produced by the Concept SDTS is resistant to extremely high temperatures.  The unit requires an inert propellant gas, and is supplied complete with a CO2 cylinder and regulator.

It is capable of simply and repeatedly creating nontoxic artificial smoke, from small quantities (representative of smouldering fire) to larger quantities, with thermal buoyancy, which will activate ionisation, optical, beam and aspirating smoke detectors.

The SDTS incorporates a thermal chimney with 4 independently switched, 160w air heaters, into which the smoke is introduced.  The air within the chimney rises, carrying with it the temperature resistant smoke, and an effective, repeatable and consistent thermally buoyant smoke effect results. 

As with all of Concept's mains powered smoke systems, a class leading warranty is provided.

The precision machined heat exchanger has a  self purge system that initiates automatically after every operation, meaning that virtually no residue is left in the heat exchanger to carbon which would eventually lead to a blockage within the chamber. 

The ViCount type smoke is approved by the CNPP and used in bespoke systems specifically for smoke detector testing, and an Aviator variant is supplied, capable of running off an aircraft's own power supply.

The SDT incorporates:

  • Solid State Switching
  • PID microprocessor
  • Sub-Micron particle size (0.2 micron mmd)
  • Inert gas carrier purge
  • Remote operation
  • Thermal cut out
  • Machined heat exchanger chamber

ViCount use in Hot Fire Trainer

The machine has performed flawlessly up to this point and I purchased the machine from you at least six or seven years ago.

I have to confess I have never cleaned the orifice with the drill as you mentioned.

Actually, after the install, I have never worked on the machine again which, I am sure, is at least neglect on my part.

We originally had two smoke generators in the trainer, one fore and one aft.   The other machine (not Concepts) is quite a bit older
and it quit about two years ago but we found that the ViCount generated so much smoke we did not really need two machines.

The machine is protected from the heat of the trainer by a bulkhead with a port for the smoke to get through.

To give you an idea of the efficiency and quantity and the character of the smoke, the ceiling temperature inside the trainer as verified by two gauges reaches about 1300 degrees F. The smoke level inside the trainer is maintained quite adequately from the floor to about the
four and one half foot level but not much higher due to the temperature. We have found that it burns off at about 450 degrees F (230C).

Your smoke machine has trained hundreds of line Firefighters from all over the US including from major metropolitan Fire Departments such as Los Angeles County Fire, Pasadena Fire, San Jose Fire, Las Vegas Fire, Oakland Fire, Berkeley Fire, Sacramento Metro Fire, Cal Fire, and many federal agencies as well.

The training and experience those fire fighters receive in the intense heat and disorientingly smoky environment the ViCount helps create has without question saved lives and injuries as well as millions of dollars of property damage that may have occurred without the level of training
the ViCount helps provide.

Thank you for your help and support.
