REMBE, Brilon, Germany, has introduced the latest version of its Q-Rohr flameless dust explosion venting system which can be successfully used with metal dusts, where temperatures can be twice as high as those encountered with most other categories of dust. For this reason metal dusts create special challenges for explosion protection systems. The Q-Rohr is the first such system to be certified in accordance with DIN EN 16009.

A key advantage of the Q-Rohr is that there is no need for expensive, bulky venting ducts that require modifications to be made to existing structures. The integrated bursting disc is fitted with a signalling unit that immediately reports any incidents to the process control system. The special stainless steel mesh filter inlet ensures that the pressure rise and increased noise level associated with free vented explosions are massively reduced to negligible levels in the production room. Dust and flames are retained by the mesh filter inlet.

The system generates no running costs; false triggering damages only the bursting disc and the product remains unaffected. No regular maintenance is required, an annual visual inspection being sufficient. This and other latest explosion protection innovations will be shown by REMBE at POWTECH (Hall 4, Stand 215). www.rembe.de
