Thoroughly tested

SIPLUS extreme products undergo many tests under highly challenging and corrosive test conditions to ensure they meet the toughest requirements. Your benefit: Because SIPLUS extreme products are based on standard Siemens products, you get products that are much more resilient with no change in handling.

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.

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.

System benefits

More than just resistant

With SIPLUS extreme, you can always rely on your automation components 100 percent. You’ll enjoy not only greater flexibility but also  substantial cost savings. Learn more about the benefits offered by SIPLUS extreme.
