Furnace Optimization Technology


Harcros Chemicals Inc. is the strategic distribution partner for Emisshield Inc. in the United States. With over 30 distribution locations in the United States, as well as manufacturing facilities in the U.S. India and China; Harcros is uniquely situated to focus on refineries and petrochemical plants. With this partnership Harcros will bring space technology to this industry that will increase production, optimize energy efficiency, and decrease maintenance costs for plants throughout the U.S. 


Emisshield Inc. is the manufacturer and distributor of Emisshield Coating Systems, High Emissivity Ceramic Materials with heat re-radiation capabilities designed for industrial heat applications over a wide temperature range up to 3,100°F (1700°C). Emisshield’s core technology was originally designed and developed by NASA. Emisshield® High-Emissivity coatings are proven solution-based products that provide increased heat transfer, energy savings, production increases, downtime reductions, increased material life and lower air emissions.

Emisshield’s Key Features:


  • Thermal Stability - up to 3,100°F (1,700°C)
  • Thermal Shock - tested from -392°F (-230°C) to 2732°F (1500°C) in 3 seconds with no failure
  • Adhesion – Bonding strength > 5,000 PSI (345 Bar)
  • Applied Thickness – Between 2.0 and 4.0 Mils (50 to 100µ), depends on environment type 
  • Hemispherical Emissivity – Between 0.85 and 0.95

Emisshield can be applied in the field on existing refractories and metals during scheduled operational shutdowns with proper surface preparation and inspection. When Emisshield® is applied to the hot face of an industrial units lining, radiant and convective energy from the burners and hot gases are absorbed at the surface of the coating and reradiated evenly throughout the unit, creating a uniform temperature distribution.
