How nipple drinking system works?

The nipple drinking system works like this:

The main water supply comes from the water tank about 3 metre higher than the ground floor. An auto booster pump is needed to maintain proper water pressure at all time. Water pressure is then dropped to approximately  1.5 bar by a main line pressure regulator with a  filter. The water with lowered pressure flows through a meter where the amount of water can be read. The water is then sent through a medicine attachment to add medicine and/ vitamins to the water supply. The filtered water is sent by a plastic pipe to all the pressure regulators of  every individual drinking lines respectively.

The pressure regulator enables to set proper water pressure in the nipple line as for difference bird's grow age requires difference water flow rate. You can adjust the water pressure and it can be checked  with the water level in the viewer tube.  The nipple lines can be flushed whenever is necessary by turning the flush handle from regulate to flush position,  water will then  flushes out through the auto flush kit installed at the end of the lines.  

Nipples are fixed into thick square plastic PVC tube. The length is of the nipple pipes is 4.27 meters and supported by either aluminum profile or GI conduit pipe. You can choose how many nipples you want per line depending on your birds per square meter ratio? Nipple lines should be positioned so that the birds travel no more than 1.6 meters to nipples. Birds can trigger water flow by pecking nipple pin side or upwards from any direction. The nipple tubes are connected with a fastening clamp to keep the pipe stable. Nipple with drip cup is always recommended for helping to keep litter dry. Every Nipple line is suspended by a winching system, and is hung at 3 metre intervals.
 

Nipple drinking systems are good for all types of poultry including layers, parent stock, broilers and free-range birds.

Important tips for evaporative cooling system

1. Cooling pad surface area must match fan capacity at a proper ratio to ensure airspeed at pads is less than 2 mps.

2. Pads with 30°/60° design must install in the right direction. 30° face inside the house and 60° faces outside the house. For pads with 45°/45° design, no installation direction is required.
3. Install wire mesh on the pads to prevent rat or other pest from damaging the pads.

4. Never overrun the pump on pads in high humid weather.

5. Discharge certain amount of recycle water regularly to delute the mineral contents in the water in order not to affect the cooling efficiency.

6. Wash pads with clean water and remove dust after every flock cycle.
