Thermoguard® Precoat

Pure carbon fiber yarn septa with asymmetric pores for optimum backwashing

Engineered for high-temperature applications, Thermoguard® Precoat is manufactured with pure carbon fiber yarn and stainless steel cores, ensuring durability and resilience. Withstanding temperatures exceeding 250°F, this precoat operates efficiently in special filter and precoat operations. Its innovative asymmetric pore design facilitates robust backwash strength, optimizing resin and crud removal. Free from leachable contaminants, the pure carbon fiber ensures a clean filtration process. Maintaining a uniform pressure drop along the entire septa length guarantees even pre-coats. Specifically designed and matched to Graver Technologies Powdex® and Ecodex® resins, Thermoguard® Precoat ensures optimal working compatibility between components. With a history of 5-8 years of service life in high-temperature applications, it is ideal for fossil condensate polishing, air-cooled condenser systems, and condensate polishing in various industries.

Key Features

  • Manufactured with pure carbon fiber yarn and stainless steel cores
  • Can withstand temperatures exceeding 250°F for special filter and precoat operation
  • No leachable contaminants from the pure carbon fiber
  • Innovative asymmetric pore design facilitates maximum backwash strength to pass through the septa to the outer surface and provide optimal resin and crud removal
  • Uniform pressure drop maintained along the entire length of the septa guarantees even precoats
  • Designed and “matched” to Graver Technologies Powdex® and Ecodex® resins
  • The only septa manufactured by the same company that manufactures the powdered resins assures good working compatibility between the two components
  • A long history exceeding 5 - 8 years service life in high temperature applications

Typical Applications

  • Fossil condensate polishing at greater than 150°F, especially in once-through and super critical boilers
  • Ideal design for air cooled condenser systems
  • Condensate polishing in sugar mills, paper mills, oil refineries and other high temperature applications
  • Fuel oil separations in conjunction with Ecosorb® adsorbents
