Configuration & Documentation

These are product families. Final specifications, ordering code, availability and lead time are confirmed in the quotation.

  • Diameter values retain the catalog’s Ø notation. Confirm units, tolerances, insertion length and the final dimensional drawing before ordering.
  • The 1,600 °C limit applies to the listed high-alumina configurations, not every element or tube combination. Confirm element type, duty cycle, atmosphere and final working range.
