Electrical components must operate reliably in agriculture, whether in power distribution, control technology, or in complex automation systems. Spelsberg develops durable enclosures for this purpose that perform their functions even under the harshest conditions. Neither moisture nor aggressive chemicals, vibrations or UV radiation affect the products. The result is fewer failures, reduced maintenance costs and a significantly extended service life of the installed equipment.
Abox Pro: High load capacity for demanding applications
One example of high resilience is the junction box Abox Pro. With protection ratings up to IP69, a temperature resistance from −35 °C to +80 °C, and high chemical resistance to ammonia, fertilizers, pesticides and cleaning agents, the product is ideal for barns and outdoor areas. VDE, DLG and DNV certifications underscore the tested quality "Made and tested in Germany".
Secure electrical installations with AK Air, GEOS, TK and TG PC
The manufacturer from Schalksmühle also sets standards in the field of power distribution. The small distribution board AK Air was specifically designed for ammonia-containing stable air and humid environments. An integrated ventilation technology prevents condensation and thus reliably protects against corrosion and short circuits. For demanding outdoor installations, the GEOS empty enclosures and cabinets offer long-term security with high impact resistance according to IK09, UV resistance and a reliable sealing system "Drain Protect". The portfolio is complemented by the industrial enclosure series TK and TG PC, which are characterized by glass-fiber-reinforced material, modular adaptation options and high protection ratings.
Spelsberg products in agricultural use
Numerous references demonstrate how these innovations perform in practice. Schurr Gerätebau GmbH from Uttenweiler has relied for years on GEOS enclosures from Spelsberg for automatic brushing systems for dairy cows, pigs and goats, in order to reliably protect sensitive electronics from weather and chemicals. Alcona Automation GmbH from Beckum also installs a four-figure number of TG enclosures annually in control systems for pig and poultry houses and dairy farms. Ambic Equipment Limited also relies on customized freezer enclosures from Spelsberg for precise dosing in the field of cleaning and disinfection.
Individual solutions and tested quality for agriculture
In addition to standard products, the expert in electrical installation and enclosure technology offers comprehensive customizing services, including individual mounting points, printing, as well as complete equipping, wiring and testing. Integrated production in Germany enables short delivery times and maximum flexibility, even for special sizes or short-term projects. A decisive quality factor is also the in-house test laboratory at the headquarters in Schalksmühle. Here, products are tested under extreme conditions and certified according to international standards. In the DLG test, for example, Spelsberg enclosures withstood a 1,500-hour exposure at 750 ppm ammonia, 70 °C air temperature and 70 percent relative humidity. The independent DLG (German Agricultural Society) thus confirms the special suitability for agricultural applications.
With its broad portfolio and consistent quality focus, Spelsberg ensures that modern agricultural technology functions reliably. The innovative solutions are essential components of safe and sustainable agriculture.
