A compact smoke generator with the ability to make smoke "off power"
The Concept Colt has the ability to produce a considerable amount of smoke 'off power' using the retained energy within the high mass heat exchanger, allowing an operator to carry a generator from room to room, making smoke as required, without a trailing electrical lead.
In service with numerous fire authorities world-wide, many NATO forces (including the USN and Royal Navy for shipboard training), as well as analytical laboratories, asbestos removal specialists, and HVAC and LEV contractors, the Concept Colt has an enviable reputation for simplicity of operation and reliability.
The Concept Colt 4 variants are particularly suited to applications where extremely dense concentrations of smoke are required, or

large volumes need to be smoke logged. This is because of the very persistent nature of the smoke produced.
The Concept Colt 3 is better suited to applications where a smoke effect is required, but the effect needs to be of short duration
All Colts use a one piece aluminium canister that contains the smoke chemical and inert propellant gas required to make smoke. The canisters automatically re-seal after use, so they can be used time and time again until exhausted.
The use of the canisters reduces the number of moving parts within the machine to just one, resulting in exceptional serviceability and reliability.
Re-fillable aerosol cans are also available if required which can simply be pressurised by a hand pump, airline or inert gas supply.
