Veritrap – DPF Substrate Integrity Test

Veritrap is Ceramex’s proprietary test method for assessing the structural integrity of the ceramic substrate within Diesel Particulate Filters (DPFs). Designed as a non‑destructive diagnostic, it ensures DPF reliability and compliance throughout its service life.

How Veritrap Works

• Veritrap injects a controlled stream of benign particles into the DPF
• The test measures whether particles under 10 µm penetrate the substrate—indicating cracks or filtration failures
• Any deviations from expected threshold values triggers a fail result, alerting technicians to possible internal damage
• This method offers precise substrate integrity validation without damaging the filter; optimal for operators prioritising performance and compliance

Benefits for Heavy‑Duty Applications

Veritrap delivers invaluable assurances across heavy‑duty industries; construction, agriculture, maritime, power generation, rail, and on‑road.:

• Confirms DPF substrate integrity for rigorous duty cycles and extended lifespans.
• Supports fleet maintenance programmes with minimal downtime.
• Enhances reliability for OEMs and operators using DPFs in harsh or high‑load environments.
• Prevents unplanned operational failure by flagging early substrate damage.

Part of Ceramex’s Patented Diagnostic Suite

Veritrap complements Ceramex’s patented technologies—including Xpurge® (DPF cleaning via purified water and air), Veritex® (light‑based post‑cleaning internal imaging), and Vericat™ (catalytic coating efficiency testing). Together, these tools form an industry‑leading emissions system diagnostics ecosystem. (hyperlink the underlined)

Traceable Performance Assurance

Every Veritrap analysis is logged and stored, establishing a comprehensive digital record for each filter. This enables:

• Long‑term monitoring of substrate health
• Predictive maintenance planning
• Compliance reporting and warranty validation

Veritrap ensures that only structurally sound filters return to service after cleaning, aligning with Ceramex’s 95%+ performance promise

Vericat® – Catalytic Efficiency Testing for DPFs & DOCs

Vericat is Ceramex’s advanced offline performance test for evaluating catalyst efficiency in both Diesel Particulate Filters (DPFs) and Diesel Oxidation Catalysts (DOCs). Using borescope inspection technology, Vericat® enables operators to detect performance degradation that may have occurred during service, ensuring continued compliance and reliability.

How Vericat Works

Veritex® is a patented optical technique using light to examine the filter throughout its length. The Veritex Light identifies holes in end-plugs or walls and large cracks in substrates and Veritex® InfraRed identifies blocked pores by heating end of substrate. 

The test assesses the unit’s ability to convert pollutants as per OEM catalyst efficiency specifications, comparing against a new standard. 

Any reduction in catalyst performance is clearly identified—enabling timely maintenance or replacement. This method offers non-destructive verification without dismantling or damaging the filter substrate

Key Benefits for Heavy‑Duty Applications

Vericat delivers critical insights across demanding industries —including construction, agriculture, maritime, power generation, rail, and on‑road:

• Detects catalytic decline due to extended use in harsh operating conditions.
• Confirms filter performance post-cleaning to avoid compliance issues.
• Supports OEM and fleet maintenance standards with accurate diagnostics.
• Helps prevent increased emissions, reduced engine efficiency, and costly downtime arising from degraded catalysts.

Within Ceramex’s Patented Diagnostics Ecosystem

Vericat forms an essential part of Ceramex’s patent‑protected suite of emissions diagnostics, which also includes:

Xpurge® – aqueous DPF cleaning technology

Veritex® – light‑based inspection of internal filter condition

Veritrap™ – substrate integrity testing using benign particles

Together, these technologies underpin Ceramex’s 95%+ OEM Performance Promise, delivering validated emissions restoration at scale with complete documentation.

Traceable Assurance & Fleet Reliability

Each Vericat assessment generates a secure digital record of catalyst performance, allowing:

• Monitoring of conversion efficiency over the filter’s service life
• Data‑driven decision‑making on maintenance, warranty validations, and regulatory compliance
• Enhanced system reliability and reduced unplanned downtime across fleet operations

Vericat ensures Ceramex‑restored filters meet stringent performance standards before re‑integration into service.
