Explosion-proof Custom Engineering & Component Solutions

Standard products cannot solve every problem, particularly when facing unique challenges such as special media, extreme operating conditions, space constraints, legacy equipment retrofitting, or complex system integration. CNWINNEX Explosion-proof Custom Engineering & Component Solutions acts as your dedicated in-house Ex engineering department, providing end-to-end one-stop engineering services from concept to certification.

We possess a senior Ex engineering team and mature supply chain, capable of custom-developing various Ex components, including special material motors, intrinsically safe sensors, non-standard control panels, and multi-function junction boxes. We excel particularly in system-level engineering integration, such as designing and manufacturing complete Ex control modules compliant with DNV standards for FPSOs, or upgrading and certifying clients' existing production lines. Our customization scope covers six domains: non-standard Ex components, integrated Ex systems, extreme condition engineering, legacy equipment retrofit, multi-system deep integration, and special function/software customization.

All custom products are rigorously designed, manufactured, and verified in accordance with authoritative national and international Ex standards including CNEX, ATEX, and IECEx, with protection levels spanning the full Ex d IIC and Ex ib IIC series and ingress protection up to IP67 or higher. We deeply engage in your project's front-end design, ensuring optimal balance in safety, compliance, and functionality. What we ultimately deliver is not just a product, but a reliable engineering outcome accompanied by complete certification documentation, test reports, and ongoing technical support.

Core Value:

• Solve non-standard challenges with precise, compliant engineering answers for special applications

• Obtain a single source of responsibility—we are fully accountable for the overall performance, safety, and compliance of custom solutions

• Accelerate project execution through professional concurrent engineering management and experience, ensuring efficient delivery of complex projects
