Overview of MicronFog Fogging System
Fogging works by releasing very small droplets of water into the air. To achieve a useful effect, the fog droplets need to have a mean diameter in the region of 10 to 20 microns.
With this size of droplet, the mist or fog literally hangs in the air to create the effect that you require. You can even walk through fog and not get wet!
The Renby MicronFogTM system is a versatile system assembled from a broad range of nozzles and push fit fittings. These can be placed at precisely the location required and the tubing is so small that it can be easily disguised where this is critical
There are several different ways to generate fog or mist at micron sizes, the two main techniques used are:
- Pressurise the water to high pressures e.g. 70 Bar and use nozzles with a special impeller to atomise and thereby generate the fog.
- Inject compressed air into the water stream and force it to hit a target to atomise the water.
The Renby MicronFogTM system uses the first technique. This gives the lowest running costs, whilst producing a high quality fog.
CAUTION!
Be wary of systems that purport to produce fog or mist, using mains water pressure in the region of 6 Bar or even 20 Bar.
These systems are little more than sprinklers and will generally wet an area rather than fog it.
Their droplet sizes are often in excess of 100 microns and are more like a drizzly rain than a true fog system.
Fogging Versus Misting
Is Mist Fog?
Fog is seen when a cloud is formed at (or close to) ground level. For the the moisture to hang in the air, droplet sizes have to be very small, to be supported by the air molecules.
Official definitions are quantified by visibility i.e. the distance that you can see through it. Less than 1km, it is fog, greater, it is mist, more than 2km and it is a haze.
The Renby MicronfogTM system can produce anything from a haze to a peasouper!
