SD Auto Switchover Gas Sulfonator
SUPERIOR Modular Automatic Switchover Gas Sulfonator Series
Direct Cylinder Mounted - All Vacuum
The SUPERIORTM Series SD Modular Automatic Switchover Gas Sulfonator is a state-of-the-art, totally vacuum-operated system designed to automatically switch sulphur dioxide feed from an empty cylinder to a full cylinder. The Series SD allows round-the-clock sulfonation without being concerned about running out of sulfur dioxide when the system is unattended. Series SD Sulfonators are of the vacuum-operated solution feed type designed to mount directly on sulfur dioxide cylinder valves. A vacuum operated switchover module is mounted on the wall and connected to both sulfur dioxide vacuum regulators. A sulfur dioxide gas flow meter panel indicates the amount of sulfur dioxide being fed and may be located wherever it is safest and most convenient. Sulfur Dioxide flow rate is manually adjusted and the design permits easy addition of a number of automatic flow rate control devices. A high efficiency, water operated ejector produces the vacuum necessary to operate the system. The ejector assembly contains a back-flow check valve system to prevent pressurized water from entering the sulfonator. A spring-opposed diaphragm vacuum regulator controls the sulfur dioxide gas flow rate and also acts as the safety shut-off valve.
