Minisol Aerosol Extinguisher Formula-Salll Enclosed Space Design

Our MINISOL aerosol extinguishers are known throughout the world for their unique properties.

The most prominent features of this classic aerosol fire-extinguishing product are as follows:

• The shell is made of high-quality 304 stainless steel, the process includes polishing, edge grinding, edge pushing, and edge wrapping.
• The fire extinguishing agent adopts a high-quality S-type strontium nitrate and potassium nitrate mixed chemical compound.
• Compact and easy to install, with a designed concentration of 100 grams per cubic meter, it has extremely high fire extinguishing efficiency.
• The product is environmentally friendly and has no adverse effects on humans, the atmosphere, etc.

The aerosol fire extinguisher has a separate set of design formulas, as it is generally used in relatively small spaces, such as power distribution cabinets, car engine compartments, lithium energy storage batteries, energy storage containers, etc. The engineering design will be relatively simple.

Minisol and Tiny Aerosol Extinguisher Formula

This aerosol extinguisher formula is as below photo shows:

From the above photo, it shows:

1. M is the aerosol quality in kgs, it is total flooding quality.
2. Da is the design density in kgs/m3, 100 grams/m3 or 0.1kgs/m3.
3. Fa is the additional design factor, normally Fa is 1 because this minisol aerosol is only for small or narrow space.
4. V is the protected volume which needs to make a protection for it.

Example

To help us better understand this formula, let’s take the example of an electrical distribution cabinet.

The Distribution cabinet dimension is 1000x800x300mm, then how do you design the minisol aerosol fire extinguisher?

• Firstly, the Da is 0.1kgs/m3, and the Fa is 1.
• Secondly, we need to know the volume “V”, which is 1m*0.8m*0.3m which comes to 0.24m3.
• Thirdly, use the formula M=Da*Fa*V=0.1×0.24=0.024 kgs, to work out the aerosol compound quality, this means that we need to use 0.024 kgs or 24 grams of aerosol extinguishing agent to protect this cabinet.
• Finally, select our product model based on the dosage of the medication, we need to choose our product model AW-QH-30TH, a 30-gram aerosol extinguisher for this cabinet (1000x800x300mm).

The design formulas for MINISOL and TINY aerosols are simple, only need to follow the above steps to calculate the dosage.
