1. Water softeners and filters

• Water with high total dissolved solids will cause deposits on the humidity controls, spray nozzles, jets and valve seats.
• Therefore filter systems and water softeners are necessary to reduce the TDS content of the water used for hatchery operations.

2. Water heaters

• Hot water will be necessary for operating most hatchery tray washers and for general clean up.
• A large capacity boiler is generally used to provide hot water.

3. Compressed air

• Some incubators require compressed air to actuate the turning mechanism for the racks of eggs.
• A large central compressed air system is needed for blowing down dust and other dry cleaning in the hatchery.
