Air Misting Systems (Fogging)

Air misting is used to cool the air, reduce dust concentration, treat odours, soak the barn before cleaning/disinfection without forgettind the air misting nozzle descaling / cleaning.

Many farms also use their air misting system with a Dosatron pump:

• to treat odors and improve the air quality breathed by the animals (dosing of essential oils such as eucalyptus),
• to descale nozzles (mineral acids),
• to soak buildings (detergents sprayed at reduced pressure to increase wetting power during barn depopulation, before moving on to the cleaning and disinfection stages).

The Advantages of Dosatron Technology

When installed upstream of the medium pressure pump (70 bar minimum) of the air misting system, the Dosatron pump guarantees the correct dosage of liquid additives regardless of the variations in water pressure and flow rate.

The non-electric, self-priming Dosatron dosing pump ensures that additives are dosed under the best possible conditions. It ensures consistent dilution and makes it easy to read and adjust the dosing percentage. It can run empty (without additives) without any risk of damage and is quick and easy to service and maintain.

Recommended Installation

1. Dosatron Animal Health dosing pump D25AL (0.2 to 2% or 1 to 5%)
2. Inlet water valve (1 bar minimum).
3. 2 or 3 filters (down to 1 micron filtration level to protect the fogging nozzles and the water quality).
4. Bypass valves.
5. Option: 1 extra filter (to stop potential residues/precipitates produced by the additive).
6. 1 Valve or tap after Dosatron (fast priming / pump flushing with water when changing chemical / pump testing).
7. 1 pressure reducer.
8. 1 pressure pump (70 bar minimum) to supply the fogging nozzles.

Tips for Installing, Using and Maintaining your Dosatron

• Install 3 filters in series, down to 1 micron filtration, upstream of your Dosatron.
• Adding another filter after the Dosatron can help to remove any particles generated once the additive has been injected (filters are essential to prevent the misting nozzles from clogging).
• If installed on a drinking water main line, the installation shall comply with the applicable disconnection standards (back-flow prevention system such as Class B disconnectors...).
• The Dosatron (6 bar maximum) should be installed upstream of the medium pressure pump (usually 70 bar minimum).
• The water supply to the Dosatron must be big enough to feed the demand of the misting pressure pump depending on the maximum nozzle flow (the Dosatron must always be supplied with positive water pressure : 1 bar minimum).
• A safety relief valve can be installed between the Dosatron and the pressure pump.
• Remember to rinse the Dosatron simply injecting clear water after use.
• Remember to change the dosing pump dosing seals at least once a year.
• Please contact us for the chemical compatibility of the additives used with the different Dosatron models (Additive Safety Data Sheet).
