2 Choosing the right water bowls should be a priority in professional cattle and horse husbandry. A sufficient water supply is essential for the health of the animals. It is especially important for the animals’ well-being on hot summer’s days. Lactating cows, for example, need up to 150 litres of water and more in high heat. Animals have to be able to drink sufficient water, without barriers or stress, in order to safeguard their performance and well-being. Kerbl has been producing its own tried and tested water bowls for years. Convenience and comfort for both animals and people is our top priority. Working together with working farms and extensive field testing during the development phase allow us to tailor our products to the precise needs of the users.

3 Good to know about drinkers Water is the most important and cheapest feedstuff. Sufficient supply is essential for the animals’ welfare and health. The following aspects should be observed here: • Water quality • Availability • Temperature • Ingredients Water consumption and installation data for common animals The values and heights mentioned are approximate. Each situation will require adaptation to species and purpose. Water intake is also highly dependent on ambient temperature. Necessary water flow Use drinking bowls with a suitable water flow per minute so that the animals take in sufficient water. Examples: Dairy cow: Cows take in 5-8 L/min on average. Right after milking, a cow can drink up to 20 L/min. Horse: Water intake varies between 3.5 and 7 L/min. If the water flow cannot be increased, select a water bowl with a larger volume. This will still provide sufficient water to the animal. Cow drinking behaviour Consequences of water shortages in dairy cows • Lower milk production • Reduction of rumen activity • Less intake of dry matter • Lower urinary excretion • Higher concentration of urine contents • Increased burden on the circulatory system Type of animal Water consumption Mounting heights Number of animals/drinking station Dairy cow up to 150 L/day (stabling) – 55 - 125 L/day (grazing) 70–100 cm 10 Mother cow 35 - 75 L/day (grazing) 70–100 cm 10 Young cattle 60 - 90 L/day 60–70 cm 15 Calf 17 - 20 L/day 40–60 cm 10 Horses 20 - 60 L/day 110–120 cm 15 Pony 20 - 60 L/day 55–90 cm 15 Sheep 5 - 8 L/day Step + 50 cm 25 Share of daily water consumption per cow Time of day Milking Feeding Milking 0:00 0 % 2 % 4 % 6 % 8 % 10 % 12 % 2:00 4:00 6:00 8:00 10:00 12:00 14:00 16:00 18:00 20:00 22:00

This means animals can drink easily and quickly and that sloshing is minimised. • Animals should have a constant water supply available in order to have a positive influence on the productivity and growth of the animals. • Do not install the drinking station next to the feeding station. This would risk soaking the feed or dirtying the water bowl with food residues. • The placement of the water bowls should be oriented around the animals’ behaviour and be placed on the work walkways in order to facilitate water bowl cleaning and inspection. • At least two water stations should be installed separately for herd management. Animals can only drink undisturbed in this way. Furthermore, water bowls should not be set up in corners or dead ends; instead, place them in open areas to avoid contact between higher-ranking and low-ranking animals and to enable evasion.

Water troughs are recommended here. • For calves, water bowls with a constant water level should be used and they should be adapted to their body height. Specifics for horses A metal guard can be mounted around the water bowl if a horse hits its head or stamps a lot, in order to protect both animal and water bowl from damage. In foal rearing boxed, a distance of max. 5 cm between guard and water bowl should be maintained so that foals don’t get their legs caught.

6 Good to know about drinkers Placement of water bowls in pastures • Animals should have a constant water supply available in order to have a positive influence on the productivity and growth of the animals. • At least two water stations should be installed separately. Animals can only drink undisturbed in this way. Furthermore, water bowls should not be set up in corners, dead ends or narrow walkways; instead, place them in open areas to avoid contact between higher-ranking and low-ranking animals and to enable evasion. • Water bowls do not necessarily have to be in shaded areas. Animals will seek out cooler shade in hot temperatures. If there is a water bowl there, the animals will jostle for the water bowls and dominant animals will claim the water bowl for themselves. It is recommended to install the water bowl near a shaded rest area. • In general, the water bowls should be somewhat larger to ensure a good supply and to prevent long waiting times and jostling. • It is recommended to fix pasture water bowls to the ground so that animals cannot move them. • Pasture water bowls should be cleaned and emptied before winter. Specifics for cattle • The distance between the water bowls should be max. 200 m, otherwise water intake will decrease. • For calves, water bowls with a constant water level should be used and they should be adapted to their body height. • Findings from dairy farm practice (milking robots with grazing) show that exclusive watering in barns has no effect on the frequency of milking. However, if a water bowl is placed on the pasture, the animals spend more time grazing. No water connection available Pasture Pump The pasture pump is suitable for water bowl water intake from open waters, reservoirs and tanks and pumps water from a depth of up to max. 7 - 8 metres. However, please note the rules and regulations. The suction line may not be under pressure, e.g. from a higher intake point than the pump itself. Water tank / water container Water bowls can also be connected to water tanks or water containers. You can select either float water bowls or paddle water bowls. How it works The animal pushes the lever forward with its head. The tie rod lifts the membrane and draws water into the membrane chamber. Gravity and the tension in the membrane push the lever backwards again. The water is forced out of the membrane chamber and flows into the drinking trough. The non-return valves ensure that the water is always drawn up and pumped in the right direction. Some of the pumped water remains on the upper side of the membrane and flows into the drinking trough as soon as the membrane is reactivated during the next cycle, i.e. when the animal presses the lever again (double-stroke function).

7 Explanation of terms Bar Bar is a common unit for water pressure. The pressure in a water pipe is usually expressed in bar and indicates the force with which the water is pressed against a surface (e.g. valve surface). The water pressure can be measured using a pressure gauge. High pressure Various valves designed for high pressure or low pressure in the water line can be installed in water bowls. If the water is coming from a domestic connection or a pump system, you need a water bowl or valve designed for high pressure. KERBL water bowls have a high pressure range of between 1– 5 bar. For pressures over 5 bar we recommend installing a pressure reducer ahead of the water bowl. Low pressure If water is drawn from a pasture barrel or other raised container without a pump or additional pressure booster, a low pressure water bowl or a low pressure valve is required. KERBL water bowls have a low pressure range of between 0.3 - 1 bar. Water flow rate The water flow rate, the volume flow or flow rate is the amount of water that flows through the cross-section of the water pipe or water bowl valve per minute and is expressed in litres per minute (e.g. 8 L/min). Volt Volts are the measurement of electric voltage, expressed in V (Volts). A normal domestic installation socket has a voltage of 230 V. The voltage can be reduced to e.g. 24 V by means of a protective isolating transformers for use with water bowls. Voltages up to 48 V are not dangerous for the human body and animals. Watts Watts are the unit for electric power, expressed in W (watts). A water bowl can be operated at 230 V or 24 V. As the same heating temperature is required to keep both drinking bowls frost-free, the same electric power is required despite the different voltages (24 V = 30 watts; 230 V = 30 watts). Partition systems according to EN 1717 It should be noted that water contaminated by animals falls under category 5 according to EN 1717. If a water bowl is connected to a water line that is connected to the public water supply system and does not itself separate the water surface from the supply system via a free outflow as per EN 1717, then the water bowl installation must be separated from the public and domestic water supply using a system separator with a free outflow as per EN 1717-type AA. The right water bowl type What you should consider when selecting the right water bowl: 1. High pressure or low pressure? • High pressure – is the water bowl going to be connected to the domestic supply? • Low pressure – is the water bowl going to be supplied using a water container without a pressure booster? 2. Species and group or individual housing? • Which animals are you providing water to and how old are they? (see next water bowl valve type evaluation below) • How large is the group? • What are the water needs of each animal? • Min. water flow of the valve? • Size of the tank volume? 3. Does the water bowl have to be frost-proof, i.e. heatable? • Will the heating system for the lines be laid in the browsing area? - 24 V • Is the lines’ heating system going to be laid outside the browsing area or can it be protected from browsing? - 230 V Good to know about drinkers IBC containers – the practical alternative to pasture barrels Another option for ensuring water supply without a water connection is to use an IBC container. We offer yet another fast and easy solution for mounting a feeding bucket using our mounting plate and connector set for IBC containers.

8 Good to know about drinkers Evaluation of the water bowl valve types The various water bowl types are evaluated below with a description of their suitability for certain species. Open trough drinkers with float valve: Open water stations reflect natural drinking in nature. The animal can submerse their mouths and take in large quantities of water in a short time. Trough drinkers are suitable for all animal species, especially for lactating cattle who should take in a lot of water in a short time. Water bowl valve used: A float valve is mostly used here. The float, a floating hollow body, attached to a lever arm which opens or closes the valve nozzle through its lever action. If the set water level is not reached, the valve nozzle is opened and closed again once the water level has reached its ‘target’ again. This means there is always water in the water bowl. Float water bowl: Float water bowls are characterised by open water surfaces with a constant water level. They are especially suitable for young animals (e.g. calves), sheep, goats and animals with sensitive snouts or weaning aids. Water bowl valve used: A float valve is used here, just like in the trough drinker. The float valves used in float water bowls are mostly smaller and have a lower flow rate than in trough drinkers. Otherwise the function is the same. Pipe valve water bowl: Pipe valves are primarily suitable for animals that cannot press hard with the bridge of the nose and for skittish animals. Suitable for all animal species, especially for horses as well as individual watering stations. Potentially not suitable for beef cattle. Water bowl valve used: The pipe valve or nozzle can easily be actuated by the bridge of the animal’s nose without great effort. The water than runs through the ‘pipe’ at the lower end into the floor waterer. Paddle valve water bowl: This kind of water bowl is primarily suited for powerful animals (e.g. cattle) due to the larger force required to actuate the valve using the ‘paddle’. Water bowl valve used: The ‘paddle’ (pressure valve) actuates the valve behind it upon being pressed from the front. When the animal presses on the ‘paddle’, the valve behind it opens and water runs into the floor waterer. 221140 221851 225031 222070

Surface: Powder-coated With powder-coated bowls, an electrically conductive body (grey cast iron) is coated with powder coating and then fused to the body. the material is characterised by: • high impact strength and mechanical strength • good weather resistance • optimal cleaning possible • good corrosion resistance • eco-friendly (solvent-free) workmanship Surface: enamelled High-quality, branded ceramic compound on steel castings. the material is characterised by: • good mechanical resistance • high resistance to surface wear • good weather resistance • optimal cleaning possible • high corrosion resistance • eco-friendly (solvent-free) workmanship Plastic The material is characterised by: • higher impact strength and elasticity than steel castings • good insulating thermal properties • no surface coating required Stainless steel The material is characterised by: • very high corrosion resistance • very easy to clean • no surface coating required • very long life 221140 222020 221500 221875

10 Frost Protection Drinkers Heated 24 V water bowls – how do they work? 24 V systems are primarily used for stables where the electrical wires could be damaged by browsing and where a 230 V system could present a risk to the animals and also to people under certain circumstances. An isolating transformer (e.g. item no 222798) is required to operate one or more 24 V water bowls. The transformer reduces the mains voltage of 230 V AC to max. 24 V AC. The selected transformer should ensure that the power of the transformer is greater than the accumulated power of the connected equipment. Example: 2 x heating cables (3 metres, 30 watts; item no. 223581) + 2 x water bowls H10 (50 watts; item no. 222005) = 160 watts -> 200 watt transformer (item no. 222797) is required The transformer should never be fully utilised by the connected equipment, and the total power should certainly never exceed its limits, as otherwise the required heat output of the heating cables and water bowl heaters cannot be provided. Please also note that selecting a too small cable cross section for the lead from the transformer to the water bowl can result in the loss of a lot of power. Optimal cable length and cross section is important for keeping the water pipes and water bowls safely free from frost. Please refer to the table with the maximum supply line lengths and cross sections for the output to be transmitted. Therefore, place the transformer as close as possible to the equipment (heating cables, water bowl heaters). It must be installed away from the browsing area, protected from water and be mounted away from the spray area of the water bowl. Heated 230 V water bowls – how do they work? If the electric leads are reliably protected from browsing, then 230 V systems can also be used. The advantage of 230 V systems is in the reliable transmission of the required heating power over long distances and relatively small cable cross-sections. When using metal pipelines, the grounding clamps absolutely must be separately earthed and secured. This is for protection if browsing does occur and/or the heating cable insulation or the water bowl supply cable is damaged and this is due to the pipeline. Please note that 130 V electrical installations must be carried out by an electrician.

15 Frost-Protection Accessories Which transformer should be used? If you want to operate a water bowl with 80 watts of power (supplied), then a 100-watt transformer will suffice (item no. 222796). If you also want to connect a 24 V heating cable, simply add the current consumption (= wattage) of the cable. When selecting the transformer, plan for a power reserve of 15 % (factor 1.15). Please ensure you select the correct cable cross-section. If the cable cross-section selected is too small, it cannot transmit the full power and the water bowl system can freeze under certain circumstances despite heating. Selection of the required transformers: Calculation example for transformer: 1 x 300 watts (VA) transformer (item no. 222626) for: 2 x water bowl HP20 216 watts x 1.15 = 249 watts 246 watts < 300 watts 1 x 200 watts (VA) transformer (item no. 222797) for: 2 x water bowl H10 + 2 x heating cable 160 watts x 1.15 = 184 watts 184 watts < 200 watts Number Water Bowls / Heating Cables ​ ​ 3 Water Bowl HP20 24 Volt (item no. 222055) 3 x 73 watts = 216 watts 2 Water Bowl H10 24 Volt (item no. 222005) 2 x 50 watts = 100 watts 2 Frost Protection Heating Cable - 24 Volt (item no. 223581) 2 x 30 watts = 60 watts ​ ​ Total power: = 376 watts ​ Calculate the total power required with power reserve: ​ ​ ​ ​ 376 watts x 1.15 (+ 15 %) = 433 watts + Transformer for trough heating • transforms the voltage from 230 volts to 24 volts • can be used for all frost-free waterers • Short circuit and overload protection through easily replaceable automotive fuse in the output circuit • the transformers are also secured against overheating thanks to an integrated temperature limiter (automatic reset after cool-down) • IP 65 (transformer) / IP 20 (connection) • Produced using vacuum casting: the best possible protection against moisture, mechanical and electronic loads ​ ​ ​ Conventional car microfuses for safe operation of the installation Ref. no.

16 The following table is a quick overview of cable lengths and cross-sections: Maximum cable length in metres for the following cable cross-sections and transmittable powers: Which cable should I use? If the 24 V supply has to cover a larger distance between the transformer and the heater or the heated water bowl, please pay attention to the cable cross-section, to prevent the risk of drops in voltages along the cable’s route. Calculation to ascertain the minimum cable cross-section: Power x cable length / 3200 W/m = cable cross-section (ACable) In the example above, a distance of 25 metres between the transformer and the heater and/or water bowl and a transmittable power of 292 watts would produce the following: (292 W x 25 m: 3200 W/m) mm² = 2.3 mm² In this case, use a cable with a cross-section of at least 2.3 mm² should be used. Therefore, you should select a cable with a cross section of 2.5 mm². ​ ​ ​ ​ ​ 1.5 mm² ​ 24 m 16 m 12 m 2.5 mm² 80 m 40 m 27 m 20 m 4.0 mm² 128 m 64 m 43 m 32 m 6.0 mm² 192 m 96 m 64 m 48 m Frost-Protection Accessories Frost protection heating pipe 24 V • for heating the spur line of waterers • a 24 V transformer is required for operation • IPX7 ​ ​ ​ Ref. no.

22 C10 circulation pump Maximum achievable length of the ring line with 3/4“ tubes or tubes with at least 20 mm inner diameter T-pieces, branches, and spur lines must be avoided within the ring pipe. Unavoidable spur lines must be protected against frost using auxiliary pipe heating. 1 metre should be deducted from the total cable length for each elbow piece and T-piece in the ring pipe. Maximum achievable length of the ring line with 1/2“ tubes or tubes with at least 15 mm inner diameter A circulation pump keeps the water in a ring pipe in permanent circulation and thus in constant motion. The risk of microbial contamination is reduced, increasing water quality. Spur lines should be avoided in circulation systems, as bacteria can multiply rapidly, particularly in stagnant water. Good water quality is a basic prerequisite of animal health. As the failure of the circulation pump and heater would lead to the ring pipe and water bowl freezing relatively quickly, suitable alarm systems (e.g. acoustic signals) should be integrated into the installation so that you can react quickly in event of failure. The circulation pump itself must be installed in a frost-free room. Max. ring line length in metres Max. ring line length in metres max. number of water bowls per ring pipe (closed ring pipe per circulation pump) max. number of water bowls per ring pipe (closed ring pipe per circulation pump) The constant circulation of the water in the ring pipe minimises freezing at low temperatures, compared to standing water. In order to keep the ring pipe frostfree even at very low temperatures, the C10 circulation pump also has a 3 kW heating element that heats the water and can be switched on manually if required. The heating element automatically switches on if the temperature drops below the set thermostat temperature. Insulated pipelines are a basic prerequisite for proper functioning. The maximum practical length of the ring pipe is 250 metres, and depends heavily on the number of installed water bowls, branch lines and arches. insulated polyethylene pipeline length insulated galvanised steel pipeline length non-insulated polyethylene pipeline length non-insulated galvanised steel pipeline length insulated polyethylene pipeline length insulated galvanised steel pipeline length non-insulated polyethylene pipeline length non-insulated galvanised steel pipeline length 1 2 3 4 5 6 7 8 9 1011121314151617181920 0 50 100 150 200 250 123456789101112 0 20 40 60 80 100 120 140

24 Frost Protection Drinkers With thermal water bowls, also called ball water bowls, the water bowls are kept frost-free in winter freezing temperatures even without electricity if enough animals frequent the water bowl. The water line must be routed to the water bowl in a frost-free area of the ground (approx. 0.8 metres under the surface. Constant water intake by the animals means that earth-warmed water (approx. +5 °C) can continue to flow into the water bowl and is kept at temperature and thus frost-free by the bowl walls, which are insulated with thermal foam, and the bowl lid. The balls, also filled with thermal foam, close the drinking openings in the lid after ever use by the animal, preventing the water cooling too quickly and thus freezing. When drinking, the animal pushes the ball inwards and to the side. The water bowl’s good thermal insulation means the water stays pleasantly cool even in the summer, ensuring a pleasant drinking temperature all year round. The ball closure at the drinking holes largely prevents contamination of the water. The thermal water bowls have at least one plug so that water and dirt can be quickly drained from the water bowl. In order to reduce any potential manure entering the drinking station, it is recommended to mount the heated water bowls on a concrete base of at least 20 cm height according to the installation instructions.
