How to make good foam

To make a good foam you need

• Enough air at the right pressure
• The correct detergent at the right concentration
• Enough, but not too, much water
• A hose in the correct length

What influences the foam in different systems?

Manual system based on injectors DECENTRAL:

Foam quality depends on:

• Injector: pressure/vacuum

• Accessories: hose, foam nozzle, gun/valve and hose reel

• Settings: concentration and air pressure

• Foam product*

Automatic systems DECENTRAL:

Foam quality depends on:

• Injector: pressure/ vacuum

• Flow in injector: injector size and water nozzle

• Settings: concentration and air pressure

• Foamproduct*

• Size and length of piping

• Nozzle size in nozzlebars (total volume in relation to injector size)

Manual system based on pre-diluted product CENTRAL:

Foam quality depends on:

• Pressure of diluted product (6-12 bar)

• Foamproduct*

• Settings: air pressure and volume of pre-diluted product

• Accessories: foam nozzle, hose, gun/valve and hose reel

Automatic systems CENTRAL:

Foam quality depends on:

• The concentration of the pre-diluted chemicals

• Amount of air

• Amount of pre-diluted chemicals

• Foamproduct*

• Pressure available

• Size and length of piping

• Nozzle size in nozzlebars (total volume in relation to injector size)

* Chlor-alkalineproducts have different additives(tensides), which does not foam as good as non-chlor products.
