eltherms’ Clean Laser Seal technology takes Mineral Insulated (MI) Trace Heater assemblies to the next level.
Manufactured and assembled entirely from high quality stainless steel or Alloy 825, eltherm‘s revolutionary Clean Laser Seal Technology (CLS) guarantees performance and reliability in all industrial operations.
CLS offers today‘s best possible protection from stress corrosion cracking in applications in which aggressive chemicals may be present.
Stainless steel and Alloy 825 is the material of choice for temperature process control and ideally suited for freeze protection or viscosity control applications subject to periodic high temperature exposure.
Our proprietary clean laser sealing process provides a 100% stable, homogeneous system, resulting in a reliable and maintenance-free assembly.
