ACCO brings deep expertise in regulated environments and we understand the requirements that govern them.
We design and execute systems in compliance with:

  • FDA regulations and CFRs
  • CDC and NIH guidelines
  • ASME Bio-Process Engineering Standards
  • ISPE Baseline Guides
Specialized Systems

Our team supports cGMP and GLP facilities, vivariums, and advanced technology environments.
Systems include:

  • Bulk chemical distribution
  • Ultra-high purity water, including WFI
  • Clean-in-place (CIP) solvents
  • High-purity gas distribution
Validation-Ready from Day One

ACCO’s engineering Turnover Package and Commissioning programs accelerate your path to validation. Documentation begins before procurement to ensure consistency across every system.

Semiconductor

ACCO provides end-to-end mechanical and process piping solutions specifically engineered for the rigorous demands of semiconductor fabrication. We offer a single point of responsibility for the design, installation, and commissioning of mission-critical Fab infrastructure.

Engineering & Execution
  • Design & Modeling: We develop detailed P&IDs and 3D BIM models for complex sub-fab layouts, ensuring precision fit and optimized chemical/gas delivery.
  • UHP Fabrication: Our team utilizes cleanroom pre-fabrication and orbital welding to meet the most stringent purity standards for high-stakes environments.
  • Validation-Ready Turnover: We provide comprehensive Engineering Turnover Packages (ETP), including weld logs and analytical testing, to ensure systems are fully documented and “Tool-Ready.”
Specialized System Expertise

From R&D labs to High-Volume Manufacturing (HVM), we deliver high-performance systems including:

  • UHP Gas & Chemical Distribution: Specialized delivery for toxic, flammable, and inert gases.
  • Ultrapure Water (UPW): Advanced circulation loops meeting strict SEMI standards.
  • Facility Support: Process Cooling Water (PCW), slurry distribution, and scrubbed exhaust systems.
Proven Industry Leaders

With a portfolio that includes Intel, KLA, and IBM, ACCO has the specialized experience to manage the complexities of modern semiconductor facilities.

Advanced Manufacturing

ACCO Engineered Systems delivers advanced manufacturing process piping with the rigor required for pharmaceutical, aerospace, and battery facilities. In these environments, systems must protect product integrity while safely managing hazardous materials.

We design and execute systems engineered for:

  • Ultra-clean, particle-sensitive production
  • Hazardous chemical and gas handling
  • High-pressure and high-purity process demands
  • Strict manufacturing compliance standards
High-Purity & Ultra-High Purity Expertise

Our teams support facilities where microscopic contamination is unacceptable. Capabilities include:

  • Certified orbital welding programs with weld mapping and tracking
  • Borescope inspection and documented turnover packages
  • Precision fabrication using 316L stainless steel, PVDF, and PFA
  • QA/QC programs that verify every weld and material
Cleanroom Construction Protocols

Installation practices are designed to protect system cleanliness from day one. Practices include:

  • Cleanroom tenting and controlled installation zones
  • Purge gas management during welding
  • Particle-control handling procedures
  • Precision tool fit-up for complex manufacturing equipment
Specialized Chemical & Gas Systems

We execute piping systems that safely transport aggressive or hazardous media. Systems include:

  • Double-containment piping networks
  • Integrated gas cabinet connections
  • ASME B31.3 process piping installations
  • Corrosion-resistant chemical distribution
Modularization & Tool Integration

Advanced manufacturing projects benefit from off-site fabrication and precision assembly. Capabilities include:

  • Modular skid fabrication for DI and chemical systems
  • Preassembled steel-framed process packages
  • Coordinated tool hook-up and final fit-up
  • Installation sequencing that protects schedule and quality
Documentation & Validation-Ready Delivery

Traceability and documentation are built into every phase of construction. Material records, inspection logs, and testing documentation are compiled into comprehensive turnover packages to support commissioning, validation, and long-term operational confidence.
