KHLAB Cleanroom Engineering & Construction Services

Overview

KHLAB Cleanroom Engineering & Construction Services deliver turnkey cleanroom solutions for laboratory and industrial facilities requiring controlled environmental conditions. Engineered in strict compliance with national and international cleanroom standards—including GB 50073 (Cleanroom Design Code), GB 50457 (Good Manufacturing Practice for Pharmaceutical Plants), GB 50472 (Design Code for Cleanrooms in Biotechnology Facilities), and WHO/ICH GMP guidelines—these systems support precise control of airborne particulate concentration, temperature, humidity, pressure differential, and airflow uniformity. The service portfolio spans Class 1 (ISO Class 3) to Class 300,000 (ISO Class 8) clean environments, enabling deployment across critical applications such as aseptic pharmaceutical manufacturing, microelectronics fabrication, sterile medical device assembly, and hygienic food packaging lines.

Key Features

• End-to-end project execution: integrated planning, architectural design, HVAC system engineering, cleanroom enclosure construction, validation protocol development, and commissioning support.
• Modular and custom-built cleanroom configurations—including hardwall, softwall, and pass-through chamber solutions—optimized for spatial constraints and operational workflow requirements.
• Comprehensive environmental control architecture featuring HEPA/ULPA filtration, laminar or turbulent airflow management, interlocked access systems, and real-time monitoring interfaces for particle counts, differential pressure, and relative humidity.
• Dedicated engineering team with over a decade of experience in cleanroom design for regulated industries; certified personnel trained in ISO 14644-1/2, EU GMP Annex 1, and FDA guidance on aseptic processing.
• Material selection and surface finishing compliant with non-shedding, non-porous, and cleanability requirements—e.g., stainless steel framing, epoxy-coated wall panels, seamless vinyl flooring, and chemical-resistant sealants.

Sample Compatibility & Compliance

KHLAB cleanroom systems are engineered to meet the stringent physical and procedural demands of regulated laboratory and production environments. All designs adhere to classification thresholds defined in ISO 14644-1 for airborne particulate cleanliness, with verification protocols aligned with ISO 14644-2 (testing and monitoring) and ISO 14644-3 (test methods). For pharmaceutical clients, facility layouts incorporate segregated zones (e.g., Grade A/B/C/D per EU GMP Annex 1), gowning sequences, airlock staging, and material transfer validation pathways. Documentation packages include Design Qualification (DQ), Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) deliverables—fully traceable and audit-ready for GLP, GMP, and FDA 21 CFR Part 11 compliance.

Software & Data Management

While KHLAB’s cleanroom infrastructure is primarily hardware-based, integrated Building Management Systems (BMS) and Environmental Monitoring Systems (EMS) are offered as optional add-ons. These platforms provide centralized dashboards for real-time visualization of critical parameters—including viable and non-viable particle counts (via remote sensing probes), differential pressure across classified zones, temperature/humidity trends, and HVAC alarm status. Data logging supports configurable retention periods, electronic signatures, and export formats compatible with LIMS and enterprise quality management systems (QMS). Audit trails comply with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available), ensuring readiness for regulatory inspections under FDA, EMA, or NMPA frameworks.

Applications

• Pharmaceutical aseptic filling suites and API synthesis labs requiring ISO Class 5 (Grade A) laminar flow hoods and surrounding ISO Class 7/8 (Grade B/C) background environments.
• Biotechnology R&D laboratories performing cell culture, viral vector production, and gene therapy process development under validated containment conditions.
• Semiconductor and flat-panel display manufacturing cleanrooms where sub-micron particle control (<0.1 µm) and electrostatic discharge (ESD) mitigation are essential.
• FDA-registered food processing facilities implementing HACCP-aligned clean packaging lines for ready-to-eat (RTE) products and dietary supplements.
• Academic and government research centers establishing biosafety level 2 (BSL-2) or BSL-3 compatible clean laboratories for pathogen handling and vaccine development.

FAQ

Does KHLAB offer cleanroom validation and certification services?
Yes—KHLAB provides full-cycle validation support including DQ/IQ/OQ/PQ documentation, ISO 14644-1 classification testing, filter integrity testing (DOP/PAO), airflow visualization (smoke studies), and recovery time assessment.

Can KHLAB design cleanrooms for international clients outside China?
Yes—design deliverables conform to both Chinese national standards (GB series) and internationally recognized frameworks including ISO 14644, EU GMP Annex 1, and USP <797>/<800>, with bilingual engineering documentation available upon request.

What is the typical lead time for a medium-scale cleanroom project (e.g., 100–300 m²)?
From initial site survey to mechanical completion, standard timelines range from 12 to 20 weeks, depending on complexity, client review cycles, and local permitting requirements.

Are KHLAB cleanroom systems compatible with existing HVAC infrastructure?
Yes—retrofit integration is supported through detailed interface analysis, ductwork adaptation engineering, and compatibility assessments with legacy air handling units, chillers, and control systems.

Do you provide post-installation maintenance and monitoring support?
Yes—preventive maintenance contracts, filter replacement programs, annual requalification services, and 24/7 technical hotline support are available as part of extended service agreements.
