Oil-based and water-based fog - what's the difference?
Oil-based fog is much denser and hangs in the air many, many times longer than water based fog, as the fog particles don't evaporate as quickly. It is perfectly safe, non-toxic, intrinsically biodegradable and leaves no discernible residue. The oil based fog has a temperature resistance of up to 200° Celcius (392 F). The smoke is the safest in its class, outperforming water based systems substantially.

Ultra Safe Smoke
Our oil based machines have been used in hundreds of critical applications including aircraft simulators for the world's biggest aircraft manufacturers and pharmaceutical clean rooms for over 50 years without any problems arising from deposition or residue.

Extremely efficient fluid consumption
You will likely notice a reduction in smoke fluid consumption of 80 - 90% with these systems compared to water-based smoke machines for similar if not better smoke densities.

10 year warrantyZero maintenance
Virtually no routine maintenance is required
as the unit automatically purges its heater block after every smoke issue.
Four models are available for different needs. Users from fire training centres to theme parks throughout the world have selected these machines as their primary smoke system.
Each unit comes with a 10 year warranty as standard, and a lifetime guarantee on the heater block.

HEPA Filter Challenging Tests
Smoke particle size is consistently 0.2 - 0.3 microns in diameter, so they are ideal for HEPA filtration tests. ('Entertainment' fog machines' particle size are generally around 10 to 50 times larger). They can be programmed to use Ondina EL or Emery 3004 / Durasyn 164 - the approved oil chemical for HEPA tests (water based smoke is not officially suitable for these tests).

Leak Tests / Air Flow Visualisation
Ideally suited to large building envelope tests - the smoke hangs for around 4 hours without evaporating or layering (unlike water based smoke) which enables you to fill huge areas effectively and efficiently for air tightness testing work.

Ventilation / Air Handling System Tests
For impulse / PPV (positive pressure ventilation) / road tunnel / car park ventilation tests for ventilation systems, the only smoke that gives you the most superior results is from the Phantom. It remains dense and highly visible over long distances and test durations and does not evaporate due to high speed air movement. Smoke from the units can also be given thermal buoyancy - the only machine capable of this. The smoke is heated and rises, staying visible where water based smokes simply evaporate.

Wind Tunnels Visualisation / Air Flow Analysis
In LVA / PIV laser doppler anemometry the fog particles faithfully follow flow dynamics. The fog does not evaporate in fast moving air streams, ideal for open ended wind tunnels, large or small. For visual perspective in closed (recirculating) small wind tunnels (not PIV LVA) you can reprogram the machine to use type B water based fluid which disperses quickly. As the units do not utilise a fluid pump, an ultra-smooth smoke output at any output level is ensured e.g. for laminar flow.

Smoke Detector Tests
Unlike water-based smoke, oil-based smoke can be given thermal buoyancy to closely replicate hot rising smoke from a real fire. Ideal if your smoke detectors are very high up in the ceiling. The smoke from the Thermo-Resist models is persistent to 200C (392F).

Theme Parks / Installations
Reliability and running costs are the main factors for fixed installations. These machines excel in both. They can also be programmed to use oil or water based fluid for effects with long or very short hang times.

Flight Simulators
The production of a consistent smoke with an extremely small particle size is critical in ensuring that dense smoke concentrations can be achieved within the simulator whilst keeping to a minimum the actual chemical concentration within that environment. These systems utilise only a small fraction (10%) of the amount of smoke chemical as water based options. We can also supply smoke filters to extract the smoke after the training.

Fire Training
Not only does the smoke from the Thermo-Resist versions resist temperatures up to 200C (making them ideal for hot fire training), but its fluid use is unparalelled by any other machine producing such a thick, dense, persistent smoke. It is also the safest smoke available due to the huge reduction in smoke fluid chemical required to achieve complete white-out. The smoke has a very dull smell and is much less irritating compared to high concentrations of water based fog.

If requested, the unit can also be adjusted to use our water-based fluids (both quick dispersing and persistent) for further flexibility in special effects or wind tunnels (dispersion rates 30 seconds to 1.5 hours).

These professional smoke systems are specifically designed to use Pea Soup Smoke Oil 180 which produces a smoke which is temperature resistant up to 200C (392F).
These units are therefore ideally suited for hot fire training applications or for producing thermally buoyant smoke using a large heat source (eg burn tray / space heater).
For thermally buoyant smoke for smoke detector testing please also see our RSG - Realistic Smoke Generator which is a self-contained thermally buoyant smoke producing system complete with its own heating chimney.

Pea Soup industrial smoke systems are also available in stainless steel metalwork shells to special order at extra cost. This option is recommended for both cleanroom applications, as well as for heavy duty / high usage applications such as fire training, or where the equipment is likely to be used in areas of high humidity.

Export enquiries welcome.

Cylinder Bracket
Allows the 2kg CO2 cylinder to be mounted onto the side of the unit to make it a 'one piece' portable unit. Another benefit is that it makes the unit and cylinder exceptionally stable and very hard to knock over. Please note: only fits 2kg size CO2 cylinders.

PS Centrifugal Blower Fan
Continuously rated smoke sealed fan suitable for use with the unit to blow fog through ducting / pipework. Output can be ducted from fan output using 75mm diameter hose above. Comes complete with stand to allow direct use with the height of your smoke system. 240V/110V. ~4 week lead time.

Smoke Filtration Units filter smokey air effectively extracting all smoke in situations where venting the smoke to the outside is not possible. 240V/110V.

Smoke machine ducting adaptors
Ducting adaptors

25mm silicon lined flexible ducting hose

25mm neoprene flexible ducting hose



Available in three diameters:

  • 25mm
  • 50mm
  • 75mm

A steel ducting adaptor (shown left) attaches to the front of the machine to secure the position of the ducting hose inlet allowing smoke to be positioned precisely, in hard to reach places, a distance away from the machine itself, etc.

All our ducting hoses are internally lined to be smooth, thereby reducing frictional losses and smoke particle impaction.

When ducting smoke, you are restricting the smoke particles movement in a limited space and so deposition in the hose over time is inevitable with any machine. But by using a Pea Soup smoke machine and this type of hose, deposition is minimised.

  The PS60 Smoke System

The PS60 is the highest output industrial model in our range, producing approximately 60% more smoke than even the PS33T unit above at continuous, un-ramped, full output, but an incredible 138% more smoke at "Super Turbo" level which can be sustained for up to 2 minutes before a brief re-heat period of around 15 seconds.

This TWIN OUTPUT version comes fitted with a timer controller facility and a horizontal high capacity 5 litre fluid reservoir with an easy fill, wide spout inlet and integrated sight-glass, eliminating the possibility of ever overfilling the tank.

The smoke from the PS60 is extremely persistent, remaining highly visible to 200°C (compared to typical water based smoke systems which evaporate at 40-50°C) before evaporation commences, making the unit ideally suited to hot fire training applications. It is also used during carbonaceous burns to top up smoke levels in different compartments in the training facility. The smoke is also unaffected in fast moving air streams / turbulent conditions making it the perfect tool for PPV / impulse ventilation training. Custom weatherproof cover and wheeled flightcase to hold the entire system are also available.
