What Ceramex Ltd does

Ceramex Ltd is a UK-headquartered industrial services company specialising in diesel particulate filter (DPF) cleaning, inspection, testing and remanufacturing. Founded in 2011 and registered as a private limited company in England and Wales, the company operates from a 7,500m² headquarters facility in Gainsborough employing 150 people, supplemented by a 5,700m² European facility in Svit, Slovakia (70 employees), an Indian facility, a Japanese joint venture with Retrus established in 2017 (40 employees), and a North American joint venture with SRC Holdings Corporation in Eau Claire, Wisconsin operating from a 5,574m² facility since 2014. Ceramex is a wholly-owned subsidiary of Hexadex Limited and was brought under the newly formed Eminox Group of Companies in February 2026 alongside SaveGuard, Firehalt and Emission Control by Eminox.

Ceramex's technology portfolio centres on patented cleaning and inspection methods. The Xpurge® cleaning service uses deionised water and compressed air in a closed-loop aqueous process that restores filters to over 95% original performance with 30% more contaminant removal than alternatives; Flexpurge offers a complementary non-destructive cleaning option. The Veritex® inspection system uses light transmission analysis (including infrared) to detect substrate defects; Veritrap™ measures structural integrity via controlled particle injection; and Vericat™ evaluates catalyst performance using borescope inspection. The company holds ISO 9001, ISO 14001 and IATF 16949 certifications, and its procedures are OEM-approved with full traceability.

Ceramex generates revenue through a service-based and hybrid business model combining cleaning services, inspection and testing, remanufacturing, DPF service exchange (transaction-fee) and DPF replacement parts (hardware sales). Following the February 2026 Eminox integration, aftermarket parts and service are now delivered through the Emission Control by Eminox brand, providing customers with a single source for aftermarket emissions solutions. The company sells primarily through direct B2B enterprise channels to global OEMs and major fleet operators across automotive, off-highway equipment, maritime, power generation, construction, agriculture, rail and on-road commercial transport. Pricing is quote-based and not publicly disclosed, reflecting enterprise contract structures.

Products and services

• Xpurge® Cleaning Technology Patented advanced DPF cleaning service that uses deionised water and compressed air in a closed-loop process to restore filters to as-new condition, achieving over 95% original filter performance. Sold to OEMs and fleet operators.
• Flexpurge Cleaning Flexible DPF cleaning technology that delivers fast, non-destructive cleaning, removing soot and ash while preserving filter integrity, supporting evolving emissions legislation.
• Veritex® Inspection Technology Patented DPF inspection technology using light transmission analysis (with infrared variant) to examine the filter along its length, identifying holes in end-plugs or walls and large cracks in substrates, guaranteeing quality and traceability throughout refurbishment.
• Vericat® Catalyst Performance Testing Catalyst performance testing using borescope inspection to evaluate the efficiency of DPF and DOC catalytic coatings against OEM catalyst efficiency specifications, ensuring compliance with stringent emissions standards.
• Veritrap™ Substrate Integrity Test Proprietary substrate integrity test that injects a controlled stream of benign particles to assess structural integrity of the ceramic substrate within DPFs, measuring whether particles under 10µm penetrate the substrate, indicating cracks or filtration failures.
• DPF Remanufacturing Full aftertreatment remanufacturing service that helps customers extend the life and efficiency of critical DPF components, reducing waste and replacement costs.
• DPF Service Exchange Exchange service providing replacement DPF units for fleet operators requiring minimal downtime, offering immediate alternatives while customer filters are being serviced.
• DPF Replacement Direct DPF replacement service providing aftermarket parts and replacement components for emissions systems when cleaning or remanufacturing is not viable.

Expansion highlights5 records

Others

• Cormetech: Leading manufacturer of SCR catalysts used in diesel exhaust aftertreatment for power generation, marine, and heavy-duty applications. Comparable as an upstream emissions component supplier whose installed base creates downstream DPF cleaning demand that Ceramex services.

Broad incumbents

• Faurelia (FORVIA): Global Tier-1 supplier of exhaust aftertreatment systems, emissions control technologies, and clean mobility solutions. Overlaps with Ceramex in OEM aftertreatment but at much larger scale across both light-duty and heavy-duty diesel, providing benchmark pricing and capacity context.
• Johnson Matthey: Major supplier of catalysts and emissions control technologies for heavy-duty diesel and off-highway applications. Comparable as a high-quality OEM-approved aftertreatment player whose supply-chain dynamics influence DPF cleaning and reman demand.
• Tenneco (DRiV): Large global manufacturer of clean air and powertrain products, including DPF/SCR systems and aftermarket emissions service. Comparable because it covers both OE aftertreatment hardware and the cleaning/replacement aftermarket that Ceramex addresses.
• Continental Aftermarket: Major OEM and aftermarket supplier with a portfolio spanning sensors, exhaust components, and emissions diagnostics. Comparable as a broad incumbent whose aftermarket footprint shapes the competitive context for Ceramex's diagnostic and reman services.

Direct peers

• Eminox (Emission Control by Eminox): Sister company inside the Hexadex Group, focused on exhaust aftertreatment systems (EATS) for OEMs and fleets. Now restructured alongside Ceramex under the Eminox Group of Companies brand, the two businesses share customers, OEM approvals, and global delivery channels — making them the closest comparable.
• Clean Diesel Technologies (CDTi): Specialist in emissions control systems and catalysts for diesel and natural gas vehicles, with both OEM and aftermarket exposure. Comparable niche focus on diesel emissions compliance that mirrors Ceramex's heavy-duty and off-highway orientation.
• Nett Technologies: Canadian supplier of emissions aftertreatment products and DPF cleaning services for diesel engines across off-road, on-road, marine, and stationary applications. Comparable because of its dual focus on DPF hardware and cleaning/service to fleet operators.
• DCL International (DCL Catalysts): Manufacturer and rebuilder of catalytic converters, DPFs, and SCR systems serving off-road, on-road, and stationary engine markets. Comparable because it competes in the same DPF remanufacturing and replacement parts space with similar fleet and OEM customers.
• HUG Engineering: Swiss specialist in exhaust gas aftertreatment systems for heavy-duty diesel, marine, and rail applications, including DPF/SCR integration. Comparable as a niche Tier-1/2 supplier focused on emissions compliance in the same heavy-duty verticals Ceramex serves.
