ADCERAX® provides a structured operational guide to help engineering teams reduce avoidable risks, extend service intervals, and maintain consistent system output across continuous industrial processes.
-
Handling and Pre-Installation Requirements
1. Avoid mechanical shock during transportation and unpacking, as impact forces can introduce micro-defects that evolve under thermal cycling. Users should keep the modules supported from the base and prevent side pressure during movement. Stable handling reduces the probability of early structural fatigue in continuous-temperature applications.
2. Maintain a clean staging area before installation, ensuring no abrasive particles enter the channels. Foreign material can interfere with gas distribution and diminish operational uniformity. Proper preparation preserves the material’s designed flow architecture.
3. Verify compatibility with system thermal profiles, especially in long-duration heating operations. Engineering teams should cross-check maximum continuous temperatures and thermal ramps. Confirming alignment prevents material stress accumulation during operation.
-
Installation in Filtration, Thermal Storage, and Catalytic Units
1. Ensure uniform axial alignment when placing modules, preventing uneven stress accumulation during expansion and contraction. Misalignment can disturb gas flow and reduce system stability. Controlled placement supports long-term dimensional integrity.
2. Use stable support frames and non-reactive gaskets, ensuring no metal components introduce chemical contamination during operation. Material compatibility reduces the risk of reaction-induced degradation. This practice maintains consistent surface conditions for filtration or catalysis.
3. Confirm sealing integrity after installation, especially for systems relying on precise flow management. Any bypass flow reduces efficiency and accelerates loading on downstream components. Proper sealing ensures predictable thermal and gas-flow performance.
-
Routine Operation and System Monitoring
1. Monitor differential pressure trends during operation, as gradual increases indicate particulate accumulation. Early detection helps avoid unnecessary strain on the material. Predictive monitoring supports longer service intervals in continuous-flow systems.
2. Track thermal cycling frequency and amplitude, particularly in units where temperature transitions occur rapidly. Excessive cycling can affect long-term microstructural stability. Following defined temperature profiles ensures sustainable performance.
3. Maintain stable upstream process conditions, including gas composition and particulate load. Sudden variations impose stress on the ceramic substrate. Consistent process conditions enhance operational reliability.
-
Cleaning, Maintenance, and Storage Recommendations
1. Perform scheduled cleaning using non-abrasive methods, ensuring that deposited particulates are removed without altering channel geometry. Harsh tools or blasting methods should be avoided to prevent pore distortion. Gentle procedures preserve functional surface area.
2. Replace damaged modules promptly, especially if cracks or erosion marks appear during inspection. Continued use of compromised units can lead to uneven flow distribution. Immediate replacement protects overall system efficiency.
3. Store unused modules in a controlled, low-humidity environment, keeping them inside their protective crates until installation. Moisture exposure may affect surface conditions during long-term storage. Proper storage safeguards material integrity before deployment.
