Choose an ULV fogger by matching its droplet performance, output control, coverage method, chemical compatibility, and operator-safety features to your site and disinfectant label. Start by defining the area and surfaces to treat, then confirm that the product is approved for the intended application and that the fogger can apply it as directed. A fogger helps distribute solution; it does not replace cleaning, correct dilution, required contact time, or safe handling.

For farms and greenhouses, the right choice is therefore not simply the machine with the largest tank or highest output. I recommend comparing equipment against your crop layout, ventilation, power supply, treatment schedule, and maintenance capacity. Use the following steps to create a practical shortlist and a clear purchasing specification.
Begin with a written description of where, when, and how the fogger will be used. A greenhouse with narrow crop rows has different coverage needs from an empty poultry house, equipment room, or packing area. Record the approximate floor area, ceiling height, aisle widths, obstructions, surfaces, and available access to power or transport.
Also identify whether the treatment will take place between production cycles or around people, animals, or crops. These details affect chemical choice, application timing, ventilation, and personal protective equipment. Follow the disinfectant label and applicable local requirements; do not assume every disinfectant is suitable for aerosol application or every agricultural environment.
Draw a simple facility plan and mark doors, vents, fans, benches, machinery, and areas that may be shielded from the fog. For scale, one hectare equals 10,000 square metres, but floor area alone does not determine treatment time or coverage. Air movement, room shape, target surfaces, and equipment positioning can all affect how the fog is distributed.
Note practical constraints such as whether the operator must carry the machine, move it on a cart, or reach multiple rooms. In a greenhouse, consider whether the device can pass through doorways and between rows without damaging plants or irrigation lines. A short site survey often prevents a mismatch between a machine’s advertised capacity and the work that must actually be done.
Read the disinfectant’s directions before comparing foggers. Confirm its permitted application method, dilution, target organisms or use conditions, required wet contact time, surface restrictions, and any re-entry or ventilation instructions. If the label does not allow fogging or ULV application, do not use the fogger to apply that product.
ULV foggers are commonly associated with droplets in the tens-of-micrometres range; approximately 5–50 micrometres is often used as a broad reference range, not a guarantee for every machine or application. Ask the supplier how droplet size is measured and whether the specification describes a range, a median, or another measure. Droplet size can influence drift, suspension, and deposition, so match the equipment to the product instructions and your site rather than treating smaller droplets as automatically better.
Request the stated droplet-size data, liquid output or flow-rate range, tank capacity, power input, operating instructions, and recommended maintenance schedule. Clarify the conditions under which any performance figures were obtained, since settings and liquid properties may affect results. If a supplier cannot explain a specification, ask for the relevant product documentation before ordering.
Check that wetted components are suitable for the disinfectant you plan to use. Compatibility depends on the chemical formulation and materials in the liquid path, including seals, hoses, and tank components. Obtain written guidance from the fogger supplier and chemical manufacturer instead of assuming that a machine is compatible with all disinfectants.
Compare portable, trolley-mounted, and larger-capacity configurations based on how the work is organized. A portable unit may be practical for smaller rooms or tasks that require frequent repositioning, while a wheeled configuration may reduce carrying for larger indoor areas. For a multi-zone site, consider whether one unit can be moved efficiently or whether different equipment arrangements are needed.
Tank capacity should suit the planned work without making the machine unnecessarily heavy or difficult to handle. A 20-litre tank can be used as an example in a capacity-planning worksheet, but it is not a universal recommendation or a statement about any particular Kobold product. Estimate the solution required from the label, treatment plan, and confirmed equipment output, then check how often refilling and cleaning will be needed.

Look for controls that let the operator set or regulate output as required by the application. Confirm whether the unit is designed for the available electrical supply or another power source, and check cable length, mobility, and safe operating conditions. Reach matters as well: the nozzle direction and airflow should allow the operator to work methodically without directing spray toward unintended areas.
Do not select a fogger solely by its maximum output or room-coverage claim. Those figures may depend on assumptions that do not match your greenhouse or farm building. Ask how the supplier defines coverage and what operating conditions the figure assumes, then validate the setup in a controlled area according to the chemical label and workplace procedures.
Confirm the required personal protective equipment from the disinfectant label and the equipment instructions. Establish who may operate the fogger, how the work area will be secured, and how ventilation and re-entry will be managed. Fogging around workers, animals, or crops requires particular attention to product directions and site-specific risk controls.
Ask how to drain, rinse, and store the machine after use, and whether any parts require regular inspection or replacement. Residue left in the tank or liquid path may affect later operation, while incompatible cleaning methods may damage components. A clear maintenance plan helps buyers estimate ownership requirements beyond the initial purchase price.
For procurement, request a quotation that specifies the machine configuration, included accessories, documentation, spare-parts availability, warranty terms, packaging, lead time, and export requirements where relevant. Compare suppliers on the completeness and clarity of their answers, not just the quoted price. These details are especially important when ordering equipment for multiple sites or arranging repeat purchases.
Before routine use, prepare a written operating procedure based on the disinfectant label and fogger instructions. Include the room-preparation steps, dilution method, application sequence, required contact time, ventilation, re-entry conditions, and post-use cleaning. Train operators to follow the same procedure and keep records of the product, settings, date, and treated area where appropriate.
Review the process after an initial controlled application. Check whether the equipment can be positioned safely, whether the planned route is practical, and whether the treatment procedure meets label directions. If coverage or workflow is unsatisfactory, consult the chemical manufacturer and equipment supplier before changing the product, settings, or method.
As an agricultural equipment supplier, Kobold can discuss your application requirements and help you identify the product information needed for a suitable ULV fogger configuration. Share your facility type, approximate area, power availability, intended disinfectant, operating frequency, and any mobility or export requirements. This information makes it easier to assess equipment options and clarify documentation, accessories, and supply details.
For a quotation, provide the destination country, estimated quantity, preferred configuration, and target purchasing schedule. Ask us to confirm the applicable technical specifications and terms for the proposed equipment before you finalize the order. This approach supports a more informed comparison and helps align the purchase with your operating conditions.
To choose an ULV fogger for farm or greenhouse disinfection, first confirm that the disinfectant and application method are permitted for your intended use. Next, map the site and compare droplet information, output control, capacity, mobility, power, chemical compatibility, and service requirements. Finally, verify documentation and supplier terms, then establish a safe procedure for application and maintenance.
The best next step is to prepare your site and chemical details and send them to Kobold for a configuration discussion. A well-defined requirement helps you evaluate equipment on operational fit rather than headline specifications alone.
