Sprinklers

Evaporative Cooling at the feed line
Water Supply should be fed from the CENTER whenever possible. This will create shorter runs and ultimately, a better functioning system. Recommended spacing is 6’ on center. (for pipe size, see below)

Nozzle Mounting
2” x 2” x 3/16” HDG Angle Iron should be welded to the post to support the water line. They should be placed approximately 2’ above the animal’s back. Nozzles should be mounted at a 45° angle. Typical placement of nozzles is on 6’ centers to ensure some overlapping of spray.

NOTE: Be sure that nozzles are adjusted so that they do NOT spray feed or bedding.

Nozzle Types

CLAMP ON STYLE NOZZLE (Part #1R06172)
The Clamp Style Nozzle is the prefered method of attaching nozzles when using 1” pipe.
THREADED STYLE (Part #1R06172)
The Threaded Style Nozzle is used when water lines larger than 1" are used. It features a 1/4" NPT fitting. Due to the need to catch as many threads in the wall of the pipe as possible, sch 80 MUST be used with these nozzles.

 
Feed Pipe Size Selection

Note - The Specifications listed assume the following:

• Nozzles are spaced 6 feet apart
• Inlet pipe size is equal to or greater than the largest pipe at the nozzles
• There is a minimum of 25 PSI and the required GPM to the pressure reducer/filter
• Pressure reducer and filter are placed NO FURTHER than 25 feet from the first nozzle

 
Evaporative Cooling in holding areas
Water Supply should be fed from the CENTER whenever possible. This will create shorter runs and ultimately, a better functioning system. Dividing the holding area into 2 zones allows for auto shut-off of the rear section when the crowd gate reaches a predetermined point, thus conserving water. (for pipe size, see below)
 
 
 
360° Nozzle
Each 360° nozzle (Part #1R06169) will cover an area approximately 26’ in diameter at 6’ above the cows back (10’ off the floor). These heads will deliver approximately 1.5gpm when used with Seneca’s valve, pressure reducer & filter kit.

How many Nozzles do I need?
To determine how many nozzles you need, divide the square footage of the holding area by 330. Generally speaking, 10 heads or less can use a 1” line. More than 10 heads requires a 1.5” line. This formula is based on nozzles 9’-10’ off the floor. Raising the nozzle height will increase the diameter of the spray pattern; however the volume of water will remain the same and will simply be dispersed over a larger area. This formula will give you a good estimate, however the exact shape and size of the holding area will affect the exact number of nozzles required for optimum performance.

A note about Nozzle height
When installing your 360° nozzles, always measure from the floor to the bottom of the sprinkler nozzle. The effective spray diameter is measured at a point 4’ off the ground, at the approximate height of the cow’s back. (see illustration to below - note: the illustration is scaled with nozzle 9' off the floor)
 

Feed Pipe Size Selection

Note - The Specifications listed assume the following:

• Inlet pipe size is equal to or greater than the largest pipe at the nozzles
• There is a minimum of 25 PSI and the required GPM to the pressure reducer/filter
• Pressure reducer and filter are placed NO FURTHER than 25 feet from the first nozzle

Filter, Valve & Pressure Reducer Kit
Regardless of which style Evaporative Cooling system you need, (Linear or Area) it will require at least one Filter, Valve & Pressure Reducer Kit. (Shown at right. Part #1R06157)

As its name would indicate, the kit consists of a water filter to protect your sprinkler heads, a valve for turning the water on and off, and a pressure reducer to ensure the pressure remains consistent at 25psi. It is currently offered in two sizes; 1" NPT for smaller lines and 1 1/2" NPT for larger systems.

Some larger layouts may require several kits, depending on the size and configuration of your system.

For larger or more elaborate Evaporative Cooling systems that require 1-1/2" sch. 80 line you will need at least one 1-1/2" Filter, Valve & Pressure Reducer Kit. (Shown at left. Part #1R06160)

Select the type of Evaporative Cooling you are looking for from the tabs above.
(Linear - ie. Feed Line or Area - ie. Holding Area).

ASSEMBLY NOTE:
The parts shown above are sold as a complete kit, however the items must be assembled. Pay careful attention to the order and orientation of the assembly, as well as the direction of water flow. You will need 1 kit for every sprinkler line.
