Citrus canopies are often dense, rounded and variable in height, while orchard alleys may include slopes, irrigation lines and soft ground. A remote airblast sprayer must therefore be selected around canopy penetration requirements, row clearance, refill logistics and the approved spray program—not orchard area or tank volume by itself.
Fast selection answer
Start with airblast configuration -A for a three-dimensional citrus canopy. Select the model by chassis passage width, canopy requirement, refill distance and work cycle. Final pump, fan, nozzle and engine configuration must be confirmed for the orchard and the approved chemical program.
Review citrus canopy depth and restricted alleys
Record dense rounded canopy sections, gaps and low branches separately. The far side of a deep canopy can present a different deposition question from the visible outer leaves. Send the responsible specialist’s treatment requirements alongside alley clearance, irrigation hardware and refill access; those inputs guide the airblast configuration review.
Passage and turning
Use the narrowest repeatable working route, not the average row width. Allow clearance for branches, the fan housing and turning at row ends.
Canopy and refill cycle
Match airflow and nozzle layout to the canopy, then calculate tank size from the approved application volume, refill distance and desired work cycle.
RCS model range for orchard planning
| Model | Tank | Chassis width | Net weight | Selection role |
|---|---|---|---|---|
| ME-RCS120 | 120 L | 520 mm | 190 kg | Narrow access, short cycles and convenient refilling |
| ME-RCS200 | 200 L | 700 mm | 280 kg | More capacity where passage and headlands allow |
| ME-RCS300 | 300 L | 900 mm | 351 kg | Balance of capacity and manoeuvrability in wider rows |
| ME-RCS400 | 400 L | 960 mm | 420 kg | Longer cycles or denser canopies with suitable access |
| ME-RCS500 | 500 L | 980 mm | 465 kg | Higher capacity after ground and transport review |
| ME-RCS800 | 800 L | 1,100 mm | 350 kg | Large-site cycle where access, ground and transport suit the platform |
All currently published RCS models use a 200 m remote-control range. The table is a chassis-and-capacity shortlist, not a spray prescription. Fan output, pump, nozzles, pressure, application rate and operating speed must be confirmed for the crop, product label and local rules.
Why 120–400 L can all fit orchards under 100 mu
Orchard area does not determine the answer by itself. A 120 L machine may fit narrow rows and a nearby refill point. A 200 or 300 L platform can balance access and cycle length. A 400 L machine can reduce refill frequency where rows and headlands are wider or canopies require more liquid. Compare row width, single-cycle duration, refill convenience and canopy scale together.
Operating workflow
- Identify the citrus block and the approved treatment requirement before selecting a pump, fan or nozzle arrangement. Tank volume does not establish suitability for that program.
- Survey canopy depth, variable tree height, lower branches and the route around irrigation assets. Show dense and more open areas in the same block plan.
- Apply the approved calibration and deposition-review procedure to representative canopy locations. A visible airblast plume alone does not confirm the required result within the tree.
- Compare the refill cycle with the usable alley and headland, including soft ground around irrigation. Do not trade reliable access for tank capacity that the route cannot support.
- Record the completed block, approved settings, conditions and any excluded trees or interrupted rows. Review changes in canopy or treatment requirement before reusing the configuration.
Limits and safety boundaries
Remote operation changes where the operator stands; it does not remove pesticide exposure controls, drift risk, re-entry requirements or the need for training and protective equipment. Stop when wind, visibility, ground conditions, people or equipment faults move outside the approved plan.
Never infer coverage from a reach figure alone. Effective deposition depends on canopy, droplet spectrum, airflow, nozzle orientation, travel speed and weather. Validate the configuration through calibration and the responsible crop-protection process.

Procurement FAQ
Should an orchard buyer choose the largest tank that fits the budget?
No. A larger tank also changes chassis width, turning needs, transport and ground loading. Select the smallest practical platform that meets the verified work cycle and canopy plan.
Why use airblast instead of a boom?
Airblast uses fan airflow to carry droplets into a tall or dense three-dimensional canopy. Boom systems suit low or evenly arranged crops needing a controlled horizontal swath.
What information does MERI need for configuration?
Send crop and canopy dimensions, row and gate width, headland space, terrain, required application volume, refill distance, daily work target and destination requirements.
Configure the sprayer around the orchard
Send row width, canopy height and density, terrain, refill route, application volume and destination. MERI will compare the appropriate RCS airblast platforms.
