Ceramic Coatings for Heater Refractory Surfaces

Is your fired heater limited by bridge wall temperature, or firing duty? Instead of a full scale revamp, we may address these issues may by the application of Cetek’s High Emissivity Ceramic Coatings to the refractory surfaces.  Cetek High Emissivity Ceramic Coatings provide improved efficiency of radiant heat transfer from refractory surfaces in gas-fired heaters. Coating application results in:

  • Typical Productivity Benefits Raging From 2.5% to 5%
  • Fuel Savings
  • Capacity Increase
  • Reduced CO2 and NOx Emissions
  • Fiber Encapsulation
  • Decreased Bridgewall Temperatures
  • Rapid payback on investment

High Emissivity Ceramic Coating for Fired Heater Furnace Refractory

Ceramic Coating for Refractory Surfaces


The coatings have superior longevity and Cetek’s experienced technicians apply it on-site to the refractory linings of process heaters/furnaces. We provide high emissivity coating systems for every type of refractory, from dense, high alumina brick to lightweight castable and ceramic fiber modules or blankets.

The thin film emissivity coatings are inert, non-catalytic, and water-based, offering a complete environmentally safe process improvement.
The service is supported by a superior Health & Safety Program, yielding a safety record better than industry standards.
