Functional Design and Diagrams


We translate complex system requirements into clear, functional designs supported by Piping and Instrumentation Diagrams (P&ID). Using industry-standard tools and methodologies, we define the interactions between system functions and sub-functions to ensure technical alignment, compliance with customer requirements, and adherence to regulatory standards—providing a strong foundation for engineering, manufacturing, and service.

Technical Drawings


We deliver high-precision technical drawings and manufacturing-ready documentation that meet industry standards and client specifications. Our documentation ensures seamless collaboration between design, procurement, and suppliers, enabling efficient fabrication and quality control throughout the product lifecycle. 

Manufacturing/Service Sequences


We create optimized assembly and service sequences that transform raw materials or components into finished products. For each step, pre- and post-conditions are clearly defined and then combined into a complete sequence—ensuring efficiency, quality, and cost-effectiveness while minimizing errors and waste.

Work Instructions


We create clear, step-by-step work instructions customized for manufacturing, assembly, and quality control processes. Our documentation ensures repeatability, safety, and efficiency on the production floor, providing essential guidance to operators.

Diagnostics


We perform structured diagnostic analyses to identify the root causes of technical issues in complex systems, aiming to maximize system availability and uptime. This includes performing targeted procedures to trace malfunctions and performance deviations, supported by dedicated service sequences.

Module and System Integration & Testing


We integrate and validate complex modules and systems to ensure full functionality, reliability, and compliance with design specifications. This process is followed by functional testing in cleanroom environments to meet high-precision and particle contamination requirements

Field Installation & Commissioning


We support full-scale field installation and commissioning of systems, ensuring smooth deployment, configuration, calibration, and final validation. This involves coordinating multi-disciplinary installations—vacuum systems, gas lines, cooling units, and electrical modules—ensuring operational readiness under controlled environmental conditions.
