2.2.2 Supply Requirements
Always use potable water (fresh tap water, not stored in a reservoir because of micro-
organism growth) for internal and external use (because of food safety).
Input central unit
• Water temperature:
• Cold water supply: min 5 °C (41 °F), max. 40 °C (104 °F).
• Hot water supply (hot fill option): min. 5 °C (41 °F), max. 99 °C (210 °F).
The hotter the water, the less time it takes to heat the water in the boiler.
• Input pressure:
• At a flow of 16 l/min (4.2 gal/min), the dynamic pressure is > 0.5 bar (22 PSI).
• Static pressure <4 bar (56 PSI).
Preconditions
• The water supply must be available under all circumstances.
• The sum of the water lines between central unit and robot unit(s) <= 30 m (32.8 yrd).
• The water supply is measured directly at the (future) connection for the central unit.
• The water supply line inner diameter to the central unit >= 19 mm (0.75 in).
The flow rate to one central unit has to be at least 16 l/min (4.2 gal/min) at all times. Take
into account that the flow rate can decrease, if other equipment also uses water at the
same time:
• Tank cleaning.
• Pre-cooler.
• Drinking water supply for the cows.
• Shower.
• Washing machine/dishwasher.
Water supply tubes
• Diameter water supply tube from the CU to one RU: 16 mm (0.63 in).
• Diameter water supply tube from the CU to two RUs:
• From CU to Y-piece: 19 mm (0.75 in).
• From Y-piece to RU: 16 mm (0.63 in).
