Refrex® Heatshields

Radiant bottom and/or side wall burners radiate heat to the skin surface of furnace internals. As a result coke forming inside radiant coils and reformer tubes increases, and the ageing of the applicated metals is accelerated. The high velocity of the hot gas stream causes an erosive effect.

Based on her positive experiences with several "high temperature" Refrex®-applications in various industries, Insulcon has developed a Refrex® heatshields which reflect around 60% of the radiation heat. This prevent overheating of tube skin surfaces of radiant coils and reformer-tubes and to reduce surface temperature on other furnace internals like: tubesheets, manifolds tube-hangers, thermocouple parts etc.

Refrex® heatshields:

  • Prevent ageing acceleration of the tube skin surface of furnace internals
  • Decreases coke-forming in radiant coils and reformer tubes
  • Can easily be untied and fixed again, even after years of process firing
  • Easy to install
  • Lightweight
