Leak Testing

Smoke is the perfect medium for discovering where leaks are and how big they are!

Clean Room Testing

The correct functioning of HEPA filters is normally tested at the time of installation, as well as part of the routine maintenance programme.

Hot Fire Training

The majority of fire training centres and schools use gas to replicate the appearance and heat of a real fire but one thing gas doesn't produce is smoke!

Spray Booth Testing

For many years, materials containing isocyanate have been the single biggest cause of occupational asthma in the UK. Vehicle paint sprayers are 80 times more likely to develop occupational asthma than workers in other industries.

Wind Tunnel Studies

For producing a point source of smoke in a wind tunnel environment, Concept have the Aerotech smoke system, with a heated tip on the end of a thin wand.

Building Envelope Testing

The air tightness or leakage rate of a building is the uncontrolled flow of air through holes, gaps and cracks in the fabric of a building, which may not be detectable simply by looking at the outside of the building.

Large Scale External Exercises

Making smoke in a very open environment or external environment can be a challenging! An oil-based smoke generator, such as a ViCount system, can produce dramatically more artificial smoke than multiple water based systems.

Smoke Generators

Colt and Mini Colt Smoke Machines (handheld)

Incredibly easy-to-use. Their off-power capability makes them portable, extremely versatile and ideal for confined space/evacuation training, flow visualisation, etc.

Smoke Generators >
Aerosol Generators

ViCount Smoke Generators

The preferred system of major training centres worldwide. Producing a temperature resistant smoke ideal for hot training, hot smoke simulations & large scale testing, ViCount smoke is intrinsically biodegradable.

ViCount Smoke Generators >
Oil Mist Generators

Spirit 900 Smoke Machines

Smoke tracing

Air Trace Smoke Machine (handheld)

Small, light-weight and battery powered. The Air Trace is great for applications where only a minimal amount of smoke is required such as air tracing.

Air Trace Smoke Machine >
B1 Smoke Machines

B1 Smoke Machine (handheld)

More powerful than the Air Trace. This compact yet robust smoke generator is particularly helpful if you want to "top up" smoke produced from a conventional system on an ad-hoc basis.

Smoke Scrubber

Smoke Scrubbers

When no outside venting is feasible, smoke scrubbers can remove Concept smoke from the air.

Fireconsult, Sweden

"During nearly 20 years working with the firebrigade (Stockholm, Sweden) and as a Fire Consultant, I have never come across a better smoke machine that the Colt 4. 

The machine is light, easy to handle and it creates a tremendous good and realistic smoke!
