Fiberfrax® Anchor‑Loc®LT and LT Z Ceramic Fiber Modules

The Anchor-Loc® module system is an established family of ceramic fiber module products designed to meet a wide range of application requirements in a variety of heat processing vessels.

Anchor-Loc LT and Anchor-Loc LT Z grade modules combine the performance features of the proven Anchor-Loc Module attachment systems with the utilization of new Fiberfrax® Durablanket® LT and Fiberfrax® Durablanket® LT Z ceramic fiber thermal insulation from Unifrax resulting in several advantages.

  • Faster temperature cycling
  •  20 % Lower thermal conductivity
  • Increased productivity
  • Lower heat storage
  • Lower installed cost
  • Lower fuel costs
  • Easier repairs

Each type of Anchor-Loc ceramic fiber module can be easily fastened to interior steel shells of all types of heat processing equipment with several different attachment systems. The ceramic fiber blanket is secured by two alloy tubes to a metallic module anchor. Flanges on the end of the tubes effectively lock the position of the tubes relative to the anchor at the time of installation.
Anchor-Loc ceramic fiber modules are manufactured in several configurations.

A choice of attachment systems is provided to meet a wide range of application needs. The configurations consist of  Weld-Loc®, Thread-Loc®, and Anchor-Loc.

Application Story

Fiberfrax® Anchor‑Loc® LTZ and Fiberfrax® Durablanket® LT

When designing the insulation lining for an ethylene cracking furnace, it is of the utmost importance that it complies with the codes and standards as outlined by the American Petroleum Institute (API). In this application story Unifrax demonstrates the use of ethylene cracker furnace lining systems without the need for a microporous back-up option (RCF modules with microporous back-up board).
