Spraying devices may be used to prevent the cristallisation of media onto the glass and to remove dust and dirt.
Series SV (central) / SVS (sideways) spraying devices are fitted through the sightglass flanges and have the same pressure rating as the sightglass itself. They are available to suit sizes of DN 50 to DN 200 of sightglasses to DIN 28120 or similar. The spray head and the feed tubes are made from stainless steel. Either a liquid or gaseous cleaning medium may be used.
- Available in Hastelloy C22
