Sentry Equipment

Saf-T-Vise Chemical Injection Atomizers

Sentry Saf-T-Vise atomizers offer ease of use and custom configuration for maximum versatility. The Saf-T-Vise patented locking collet is simple to use and enhances operator safety by safely securing the shaft within the process stream in both low and extremely high pressure conditions. A variety of atomizer configurations are available to provide the best delivery of the required chemicals to prevent or mitigate corrosion within a pressurized process such as a pipeline.

SENTRY SAF-T-VISE ATOMIZERS – THE SAFEST CHOICE UNDER PRESSURE

Sentry Saf-T-Vise atomizers offer ease of use and custom configuration for maximum versatility. The Saf-T-Vise patented locking collet is simple to use and enhances operator safety by safely securing the shaft within the process stream in both low and extremely high pressure conditions. A variety of atomizer configurations are available to provide the best delivery of the required chemicals to prevent or mitigate corrosion within a pressurized process such as a pipeline.


Benefits

Saf-T-Vise atomizers are hand insertable (low pressure) or mechanically insertable (high pressure) into your pressurized system. With a wide range of pressure ratings available, Saf-T-Vise atomizers are the optimal choice for protecting most pressurized applications. They can be mounted in any orientation with extended insertion lengths of up to 20 feet for hard-to-access application situations. Saf-T-Vise STV-T Series insertion tools are used for mechanically inserting the atomizer shafts.
