Modules & Blanket Products

 Delta DF® Modules have the highest insulating value achievable in a ceramic fiber lining. Each module is comprised of folded blanket under compression to insure a tight  seal and a “spring-back” action not found in typical wallpaper


Noted features of a DF® Module lining are:
  • Fast & Easy installation
  • Low heat storage and fuel costs
  • Self-Supporting internal hardware reduces structural steelwork vs. castable or brick linings.
  • Bolt-On and Bolt-Thru attachment methods provide
  • versatility for retro-fits & rebuilds especially in tight areas.
  • Thermal shock resistance speeds up heat ups and cool downs for quick turn-around times.
  • Industry-leading heavy gauge hardware reduces the chance of channel tear-through during torque down.
  • Manufactured in the USA with Unifrax Blanket
  • Typical Applications for DF® Modules are:
  • Stress Relieving Furnaces
