SIPLUS extreme – automation and drive technology for extreme ambient conditions

When the standard does not meet your needs.

With SIPLUS extreme you can rely on mature, state-of-the-art automation and drive components. SIPLUS extreme products are standard products offering improved resistance to mechanical loads, chemical and biological substances, condensation, and temperature fluctuations. They’re also designed to cope with temperatures between -40° and +70° Celsius. That’s why SIPLUS extreme is the first choice for all applications where the established standard is no longer enough.

System characteristics

Ready for all requirements

To ensure that the SIPLUS extreme products are fully operational even under the harshest ambient conditions, they undergo numerous tests under high-load and corrosive conditions. They are added to the product family only after passing these tests.

Ready for snow, desert heat, or the polar sea

SIPLUS extreme products are tested for several days in a cycle of heat, cold, and moisture at temperatures from -40° to +70° Celsius. Temperature information during operation specifies the permanently permitted low and high temperature range. The start-up temperature is the lower admissible limit for putting the products into operation. The unique finish on SIPLUS extreme products means they’ll withstand 100 percent relative atmospheric humidity and will also operate flawlessly even when ice builds up.

Protection against early failure because of corrosion

Simple protective coatings are not enough. Instead, cleaning processes, material selection and coating technologies have to be coordinated so that they work together optimally. SIPLUS extreme conformal coating ensures the permanent cover of all components and solder joints, which is not the case with a simple coating. Thanks to our special, high-quality coating and optimized processes, our products achieve maximum values in environmental tests.

Resistance to medial load

After the finishing process, SIPLUS extreme products undergo tests involving various chemical substances to establish their resistance to harmful gases as required by the standards. Biological environmental conditions are recreated in a test with mold and a variety of fungal spores. These methods ensure that the hardened SIPLUS extreme products will remain resistant to potential damage.

Protected from sand and dust

The movement of a mixture of air, dust, and sand can damage electronics and lead to product failure. To ensure that the finished SIPLUS extreme products will perform in the raw materials industry and in manufacturing facilities with a high proportion of sand or dust in the air, they’re tested under these exact ambient conditions.

Resistant to high salt content

A high atmospheric salt content can cause components to fail. SIPLUS extreme products remain fully functional even under aggressive salt spray. To simulate the environmental conditions in locations close to the sea and offshore – for example, in shipyards and wind farms – SIPLUS extreme products must pass tests involving highly corrosive sodium chloride.
