These venting systems are now approved for metal dust

| By Chemical Engineering



The Q-Rohr family of indoor flameless-venting products (photo) has recently been approved for use with metal dusts. Q-Rohr systems can also be used with other types of dusts, gases and hybrid mixtures. These indoor systems eliminate the need for relocating dust collectors or other enclosures outside. The system consists of a specialized stainless-steel mesh construction and a rupture disc. An integrated signaling unit connects to any audible or visual alarm and shutdown to alert plant personnel in the event of an incident. If an incident occurs, flames are extinguished, and pressure, noise and dust are reduced to negligible levels. — Rembe, Inc., Charlotte, N.C.
