Fogging systems are used in modern poultry barns to produce a lightweight mist that hangs in the air, absorbing and removing heat from the barn through evaporative cooling. Mist from fogging systems usually doesn’t stimulate the birds and is generally used to help lower ambient air temperature in the barn.
Sprinkler systems produce a much larger water droplet that doesn’t hang in the air like mist. The droplets fall straight toward the floor and stimulate the birds to stand up when they feel water fall on them. As soon as they stand, the heat trapped between their bodies and the floor begins to dissipate and is removed by the ventilation system while the birds are also cooled by the fresh air being pulled through the barn.
The GrowerSELECT® HSWS-01 sprinkler control unit is a programmable and automatically increases the run time and frequency of the system’s operation as needed based on temperature set points. An available data plug allows settings from a controller to be stored and quickly replicated on other control units across the farm. The controller operates three different stages of cooling intervals based on the temperature inside the barn.
The GrowerSELECT sprinkler control is available as a stand-alone unit, or in packages designed to cover barns 50’ or wider and lengths from 400’ to 660’. Sprinkler packages come complete with a control unit, distribution manifold, two sensors and enough sprinkler drops (22” length) to cover the barn’s floor surface area.
GrowerSELECT sprinkler drop assemblies are available in 22” and 30” lengths. The low pressure (50 psi) rotating sprinkler assemblies cover approximately 450 square feet each and produce large water droplets that help stimulate poultry activity, releasing trapped heat between birds and litter. Each drop includes a sprinkler, drop tubing and a 3/4” x 1/8” PVC tee fitting.
The GrowerSELECT sprinkler system control activates electronic solenoid valves on the manifold station to distribute incoming water to the sprinkler drops in the building. Manifold stations are available in 2 and 4 line options, depending on the amount of sprinkler drops used in a barn. Each manifold includes an in-line filter, manual supply shut- off valve, a pressure gauge and manual distribution output shut-off valves.
