Drying costs sensation on the Bereuter family farm in Vorarlberg

Detailed picture of the farm:
Cultivable area: 28 ha grassland
Livestock: 20 dairy cows + 15 head young cattle
Drying system: -1 x HSR 50 air dehumidifier
-SR 900 15 kW ventilator
-Vario comfort control
-1 x drying box, 60m2 and 4m hay fill level
-2 x drying boxes, each 130m2 and 5.5m fill level


It is obvious at the first glance that, together with Laurin and Luca, Merbot and Andrea Bereuter manage their hay milk farm in Alberschwende in the Bregenzerwald (Vorarlberg) with loving devotion. Twenty dairy cows and 15 young cattle live on the farm. The hay required to feed them is produced on some 28 ha grassland. The best for animals and the environment has always been an important concern for the family, which is why in 2014 they decided to convert to a modern, fully automatic, intelligently-controlled hay drying system from HSR.

Independent of weather conditions

Right from the start the switch to a modern hay-drying system began paying for itself, because the HSR system made it possible for the first time to bring in hay totally independently of the weather even during very short periods of good weather and to dry this cost-effectively with energy-efficiency and to produce high-quality hay. Therefore the first cut was possible on 6th May and the last cut could be delayed until 30th September 2016 - totally impossible without modern hay-drying methods.

Minimises energy costs

The HSR drying system was particularly popular for its low operating costs.

Hitherto the Bereuters have dried their hay with a conventional oil-fired oven, which used six to seven litres of oil per hour. A considerable amount, if you take into account the length of time the oven takes to dry the hay.

The HSR system set new benchmarks here. And that was despite - possibly even because of - the rainy summer of 2016 and a mean annual rainfall of 1,760 mm. These unfavourable conditions allow the HSR system to show off its true class to best advantage.

Sensational: energy requirement as low as 48kWh per ton of hay

The HSR system monitors the current humidity of the dry material autonomously. The fully automatic drying programme constantly adjusts the entire drying process to the current measured factors. This means that hay is always dried using the exact amount of energy exactly required and thus the operator's energy requirements and energy costs plummet.

Therefore the choice of the right hay drying system is decisive with respect to energy costs. However, the Bereuter family have done everything correctly, from harvesting in the field to filling the hay boxes. Together we have achieved a sensational result.

In 2016 a total of 10,500 kWh of electric power was used for the drying system. At a mean electricity price (day-time and night-time consumption) of €0.15 per kWh electricity costs in the amount of €1,575.00 were reached; this equates to drying costs in the amount of 0.9 cents per kilogram of hay for an annual hay volume of 170,000 kg.

In 2015 costs fell short of these very low values, since only 8,300kWh were consumed; this gave energy costs of only 0.7 cents per kilogram of hay. Calculated per ton, this gives an approximate energy requirement of a sensational 48kWh per ton of hay.

Improving quality

It was not only the costs which decreased with the HSR-dried hay. In matters of quality there was an enormous leap forward. Already in 2015, immediately after the conversion the first cut was awarded 5th place in the Vorarlberg Silage and Hay Championship 2015. And things keep getting better! In 2016 the Bereuters were awarded 4th place in a competition for the whole of Austria.

Auszeichnung der Familie Bereuter

Pure pleasure

The many holiday-on-the-farm guests at the Bereuters' specialised baby and child farm (www.ferien-bereuter.at) with its Four-Flower award also notice these high standards. A delicious scent of hay greets large and small guests when they wake up and accompanies them throughout the house. You cannot get enough of this pleasant scent.


A huge success for HSR and in particular for the Bereuter family. We are proud to have been chosen by such pleasant, professional farmers to supply the technology to save energy and protect the nutritional value of the hay, which is their most important animal feed. Our sincere thanks to Vorarlberg!
