Frost-Free Water Bowls

Systems with 24 volts are primarily used in stables where the electrical cables could be damaged by browsing and could pose a risk to animals and possibly also to people with a 230 volt system.

A protective isolating transformer (e.g. item no. 222798) is required to operate one or more drinking bowls with 24 volts. The transformer reduces the mains voltage from 230 volts AC to max. 24 volts AC. The transformer must be selected so that the power of the transformer is greater than the total power of the connected loads.

Example:
2 x heating cables (3 metres, 30 watts; art. no. 223581) + 2 x drinking bowls H10 (50 watts; art. no. 222005) = 160 watts
-> 200 watt transformer (item no. 222797) required

he transformer should never be fully utilised with the connected consumers or even exceed the total output, as otherwise the required heat output of the heating cables and drinking trough heaters can no longer be provided.

Please also note that if the cable cross-section of the supply line from the transformer to the drinking trough is too small, a lot of power can be lost. In order to keep the water pipes and drinking troughs safely frost-free, it is important to optimise the length and cross-section of the cable. Please refer to the table with the maximum cable lengths and cross-sections for the power to be transmitted.

Therefore, place the transformer as close as possible to the consumer (heating cable, drinking trough heater). It must be installed outside the browsing area, protected from water and mounted outside the splash zone of the drinking trough.

If the electrical cables are reliably protected against browsing, 230 volt systems can also be used. The advantage of 230 V systems lies in the reliable transmission of the required heating power over long distances and relatively small cable cross-sections.

When using metal pipework, the earthing clamps must be separately earthed and fused. This serves as protection in the event of a bite and/or damage to the protective insulation of the heating cable or the supply cable to the drinking trough, which is in contact with the pipework.

Please note that electrical installations with 230 volts must be carried out by a specialist!

With thermal drinkers, also known as ball drinkers, the drinkers are reliably kept frost-free in winter at sub-zero temperatures, even without a power supply, if enough animals frequent the drinker. The water supply pipe must be laid in the frost-free area of the floor (approx. 0.8 metres below the surface) to the drinking trough. By constantly drawing water from the animals, water at ground temperature (approx. +5 °C) can flow into the drinking trough and is kept at temperature and thus frost-free by the drinking trough wall insulated with thermal foam and the drinking trough lid.

The balls, which are also filled with thermal foam, close the drinking openings in the lid after each use by the animal and thus prevent the water from cooling down too quickly and freezing. When drinking, the animal pushes the ball inwards to the side.

Thanks to the drinking trough's good thermal insulation, the water remains pleasantly cool even in summer and ensures a comfortable drinking temperature all year round. The ball closure of the drinking openings prevents contamination of the water as far as possible. For easier cleaning, the thermal drinkers are fitted with at least one drain plug so that water and dirt can be quickly drained from the drinker. In order to reduce the possibility of excrement accumulating at the drinking point, it is recommended that the thermal drinkers are mounted on a concrete base at least 20 cm high in accordance with the installation instructions.
