Reotemp® Lagging Sanitary Tri-Clamp Thermowell (STL)
Reotemp® sanitary thermowells make it possible to remove an instrument without dropping pressure or losing contents of the process and protect the instrument from getting bent by the process media. Each 316L stainless steel thermowell is die stamped, finished to 32Ra, and has a tri-clamp connection which allows for easy cleaning to prevent contamination of the process. They are used in the dairy, food processing and pharmaceutical industries.
These lagging sanitary thermowells are offered in 316L stainless steel in 1.5", 2", 2.5" and 3" tri-clamp connections with element lengths 6", 9", and 12". If you are looking for additional options, like a different element length, connection size, or material, please reach out to our sales team.
Quick Guide: Standard Thermowells vs. Lagging Thermowells
Standard Thermowells are the most commonly used type. They are directly installed into the process media, offering reliable protection for the temperature sensor against high pressure, corrosive environments, or mechanical forces. These thermowells are straightforward in design, often crafted from stainless steel or other corrosion-resistant materials to ensure longevity in demanding applications.
If you are looking for more in-depth information, read our blog post on understanding the differences between standard and lagging thermowells.
