Conventional sight glasses are often dirty and hinder a clear view in process rooms. The self-cleaning sight glass from the Catalan process equipment manufacturer Riera Nadeu can be used for any kind of equipment which requires permanent visibility into the interior. The Rina RSG – Rina rotating sight glass – is a dynamic sight glass that stays clean during the entire operation. It uses the centrifugal force to keep itself clean and dry. The Rina RSG consists of a static frame on which a pneumatically driven motor is mounted. In this frame, both – a static glass and a dynamic glass are mounted one behind the other. On the frame is a purge line for nitrogen (or clean air) which permanently flushes the space between the static and dynamic glass. The continuous circulation of nitrogen is used for blanketing as well as for generating an overpressure in order to avoid fogging and/or ingress of media which would hinder clear visibility through the windows. The extremely high rotational speed of the dynamic glass (18,000 min-1) prevents the adhesion of moisture or sticking of products. In addition, there are no rotating parts causing friction. The air of the drive ensures cooling and thus supports the nitrogen purge while avoiding heat transfer of the rotating glass.
