The Ex switch which came in from the cold - Switchgear and sensors for subzero applications

Canada, Kamchatka, Barents Sea: exploration and extraction of oil and gas as raw energy sources are increasingly taking place in regions which are freezing cold. Electrotechnical components also have to cope with minus degrees in other areas of process engineering. Switchgear and sensors are now available for just such applications, suitable for explosive environments and temperatures down to -60°C.

Where there is one extreme condition, the next is not far away - Ex position switches and Ex magnetic sensors down to -60°C

Subzero temperatures, humidity, explosive atmospheres: in process engineering the conditions for switchgear applications can often rightly be described as extreme. The steute Extreme business unit has developed special ranges for just such conditions. They include standard position switches and magnetic sensors for explosive environments in temperatures down to -60°C.

Mooring: advanced course

The anchoring of larger ships is often managed not with bollards, but with electromechanical mooring systems. The switchgear used to control these systems must be able to withstand extreme ambient conditions.

Wireless technology for Ex zones

When switching devices require no power cables and “radio” their signals from the field, this is usually a huge advantage, depending on the application. Wireless switches and sensors can be used in locations that are difficult to access after the installation. The benefits of wireless switchgear technology in Ex zones are also being increasingly appreciated. steute offers a wide range of certified wireless Ex switchgear for this task.
