Leading Global Biosimilars Manufacturer Improves ISO 5 Cleanroom Aseptic Compliance With T-FIT® Insulation

Background

A leading global biosimilars manufacturer, headquartered in India with operations across India and Malaysia, supplies life‑saving biologic medicines to more than 120 countries worldwide. Operating large‑scale, highly regulated ISO 5 aseptic manufacturing environments, the company is committed to innovation, continuous improvement, and strict adherence to global Good Manufacturing Practices (GMP) and FDA regulatory standards.

Within its aseptic bioreactor operations, insulation performance is critical. Not only for thermal control, but also for compliance with particulate and sterility expectations in Grade A / ISO 5 cleanroom environments.

The Challenge

The client was experiencing persistent challenges with conventional nitrile rubber insulation used on equipment within aseptic processing areas.

Over time, the insulation material was prone to particle shedding, introducing non-viable particulates into open sterile product paths. This issue presented several risks:

• Increased sterility assurance concerns, as rubber particles can act as carriers for microorganisms
• Difficulty meeting GMP regulatory expectations for both viable and non-viable particulate control
• Condensation formation, which is treated as a “leak” in aseptic manufacturing environments
• Limitations when retrofitting insulation within active ISO 5 cleanrooms without breaching protocol.

These challenges were not unique to one site, but reflective of wider constraints faced across biosimilars manufacturing when traditional insulation materials are used in aseptic zones.

The biosimilars manufacturer required an insulation solution that could be installed without disrupting ISO 5 cleanroom operations, eliminate particle shedding, prevent condensation, and fully support GMP compliance.

The Solution

The manufacturer selected T-FIT® Clean insulation based on T-FIT’s service-led, problem-solving approach and proven methodology in regulated aseptic environments.

The project focused on retrofitting insulation on bioreactor systems within an aseptic area. To ensure performance and compliance:

• T‑FIT® engineers optimised insulation thickness using thermal calculations, factoring in ambient conditions and process cycles, to fully eliminate condensation risk
• The insulation design addressed both thermal control and particulate integrity, preventing material degradation and shedding
• A bespoke bottom dish sheet was engineered, with all dimensions and tolerances calculated and validated to achieve 100% accuracy
• Installation was completed under strict aseptic constraints, with limited time on site and restricted tool usage

Competing insulation materials were considered, but failed to address the combined requirements of condensation control, particle integrity, and aseptic suitability. T‑FIT® was implemented within a three‑week timeframe, from solution confirmation to successful installation within the ISO 5 Cleanrooms.

The Results

Following installation, the aseptic cleanroom insulation delivered results that exceeded expectations.

• The biosimilar manufacturer successfully met current GMP and aseptic FDA regulatory requirements
• Particle shedding was eliminated, addressing a key audit and sterility risk for ISO 5 cleanroom environments
• Condensation was prevented, removing a critical non‑compliance issue
• The biopharmaceutical site passed subsequent regulatory audits following installation
• The improved insulation performance supported process optimisation and increased production yield

While energy‑saving data is still being evaluated, early indicators suggest reduced refrigeration losses due to improved thermal efficiency.

This ISO 5 Cleanroom project has since been identified internally as a benchmark reference for aseptic insulation performance within biopharmaceutical manufacturing environments.
