Cooling livestock through European heatwaves

The three cooling methods, honestly compared

Each has a place in European housing — the mistake is using one for a job it does not do.

• Fans: move air across animals, cheap and familiar, but they stop helping as air temperature approaches body temperature.
• Sprinklers and soakers: wet the animal; effective for cattle, but water use is high and bedding, floors and hooves pay for it.
• High-pressure fogging: cools the air with droplets that evaporate before landing. Low water use, drier floors, and it works in holding areas where fans alone fall short.

Where fogging fits in a European building

In practice we specify it for specific zones rather than whole buildings:

• Milking holding pens, where cows stand crowded and cannot be moved
• Pig finishing and farrowing areas where wet floors cause problems
• Poultry houses, fogging into the incoming air path rather than over the birds
• Feed and loafing areas under shade structures

Humidity is the control variable here

European heatwaves are often humid, and adding moisture to saturated air does nothing for the animals. Our controllers read temperature and humidity and throttle back as humidity rises — this is why humidity-linked control is part of the specification rather than an upgrade. Water quality also matters more than most buyers expect: hard or iron-bearing water blocks fine nozzles, so inlet filtration (5 μm) and a cleaning interval are specified with every system.
