About us

Heutrocknung SR GmbH's story starts with the farmer Josef Reindl, who tested and developed air dehumidifers on his own farm for eight years. 

In 2009 the time was right: Reindl founded his company Heutrocknung SR, in order to make the success attained with his hay drying systems available to other farmers. The immense interest in his product surpassed his highest expectations, and he expanded his team. 

Scientific institutions such as the Raumberg-Gumpenstein Research Institute confirm the advantages of air dehumdifying technology. After only three years - in the summer of 2012 - our systems are in operation from the Baltic sea to Mallorca.

Due to expansion, the limited company became Heutrocknung SR GmbH in 2010. It has been and will always be our aim to supply the right hay drying system for every single agricultural business. This is the reason we extend our range year on year. 

Comfort control constitutes a massive and important jump in development. In accordance with our motto "By farmers - for farmers", the control unit allows the simplification and improvement of the drying process in the farmer's daily work, allows a lower dimension in power supply and therefore requires less electricity. 


Our company history and continuous technical development of our systems display an on-going parallel expressed in our mission statement:

Hay-drying is a skilled art of achieving maximum drying success with as little electricity consumption as possible!
