Central
control system
For ten years now HSR Heutrocknung has been developing intelligent control systems to automate the entire drying process. The key point here is the efficiency of drying. On the basis of Measurement values from a variety of temperature and humidity sensors the control system determines which type of operation (indoor air, fresh air or mixed air) is most effective.

Everything is digital
Everything is digital
HSR Heutrocknung offers a central control system developed in-house especially for hay drying requirements, as well as for other materials, such as the drying of wood, cereals, herbs, and many more. The control system has been developed with the specific technical and agricultural background of farmer and founder of the firm, Josef Reindl.
A wealth of features
A wealth of features
The modern, clear control system displays all the data relevant to hay drying and to cooling technology on one screen. Its many features include double racing fittings, 24 hour interval drying, and current limitation during stall times.
Maximum convenience
Maximum convenience
The control system can run fully automatically in "Automatic" operation, which spares the farmer a great deal of work. Even more convenience in operation is ensured by the optional offset display of the HSR Connect modules installed in control systems operated by Smartphone or tablet.
HSR Heutrocknung offers a wide variety of different control systems for different applications

The HSR Connect module is a 1:1 visualisation of the drying process on a Smartphone or a tablet. This feature allows you to inspect and intervene in the entire drying process directly from the sofa from your mobile phone. More information on HSR Connect
Upgrade of new features in older control systems
The key component of HSR air dehumidifiers is the central control system, which we have developed. Over the last ten years we have continually been expanding the functions of this control system. Based on the know-how of farmer and founder of the firm, Josef Reindl the central control system is in addition now expanded and optimised on the basis of feedback from more than 1,000 customers.
So that our loyal customers may benefit from the further developments, we always endeavour to make innovations available as updates (software updates and hardware updates). You can have the following features upgraded (see table below). Your representative is there to support you in deciding the details of your completed project and to give you a quotation.

Helpful additional features and modules
In order to relieve the daily workload, both the large 12" central control system and the 5.7" central control system offer a range of features, which are activated as standard in the control system. In addition there are useful features, which have been designed for specific user requirements. These are:

Offset display
Offset display
The display from the dehumidifier is installed in a separate metal housing (approx. 55 x 40 x 15 cm). This housing can be mounted in a position of your choice.* This may be at the entrance to the hay barn or in your farmhouse. *The dehumidifier and the offset display are connected through a data cable, the required length of which must be clarified with our sales department.

Generator start / waste heat utilisation
Generator start / waste heat utilisation
The emergency power generator on the Vario Elite is controlled by a start/stop module with appropriate after-running cycles. Vario Elite+ regulates the targeted drying area in use fully automatically via various shutters and in this way feeds in waste heat. Indicators such as fuel are displayed on the generator - also in a mobile version with HSR Connect. Because use is different for individual purposes and depends on the generator used, we recommend that you contact our sales team.

Cable winch module
Cable winch module
The cable winch module makes it possible for the cable winch to be operated for an exhaust air window or similar. The cable winch is already included in the cable winch module. Under our warranty cable winches from third-party suppliers may not be operated with our control system.

Auxiliary heating system
Auxiliary heating system
Additional heating by means of a heat coil or a domestic heating system makes the drying process even more effective. The auxiliary heating system module, which we offer, allows the relevant components to be integrated into the drying process. Please contact our sales force for detailed advice.

Box positions and hay boxes
Box positions and hay boxes
Up to five hay boxes with linear connection are included in the 12" control system and up to 3 hay boxes in the 5.7" control system. We offer the "Box Positions" expansion module for additional boxes or special positions in the channel, such as 2 left/3 right or 2 left/1 centre/2 right, and so on. In this module a variety of special cylinder designs can be created at low cost.

Software subscription
Software subscription
We are always trying to obtain the maximum performance from our control system. In the last few years innovations, such as the Elite regulation or calculation in accordance with the HX diagram or the positive energy balance, have had a substantial effect on the energy efficiency of our drying plants. By taking out a software subscription you receive all the updates for 2, 3 or 4 years and are always guaranteed the most recent software for drying your hay.

Special programming
Special programming
You have particularly specific requirements for drying your hay? We will be pleased to develop our control system further, in close consultation with you, and to adapt it to your needs. In recent years we have set up numerous projects, such as a drying system of 17 boxes containing different material to be dried. We look forward to your enquiry.
Box drying and round bale drying
The VARIO Comfort control system (12“ und 5.7“) dries loose hay, round bales, wood, maize, cereals and much more. When purchasing, please specify the relevant material to be dried and this will be updated in the control system during initial commissioning. In various computer programs the drying temperature and drying period are adapted for drying loose hay, round bales, wood, etc.
Tray drying
Tray drying can be used for drying herbs, hemp or tobacco. In this process the material to be dried is spread out on different trays, which are then also dried in accordance with pre-defined programs. The temperature and humidity sensors installed detect the corresponding real values.
As long ago as 2011 HSR Heutrocknung designed its first herb drying plant. Continuous further development and intensive discussions with the drying plant operators are continually improving our herb drying plant.
More information on herb drying - Bergsmann Farm Project is available in our hay blog.
