BIOCOOL LYO-20 Production-Scale Freeze Dryer

Overview

The BIOCOOL LYO-20 is a GMP-compliant, production-scale vacuum freeze dryer engineered for robust, repeatable lyophilization of pharmaceuticals, biologics, diagnostics, and high-value industrial formulations. It operates on the fundamental principle of sublimation—removing water from frozen product under controlled low-pressure conditions while maintaining structural integrity and biological activity. Designed for continuous batch processing in regulated manufacturing environments, the LYO-20 integrates precision thermal control, high-efficiency condensation, and full-cycle automation to support validation-ready operations compliant with ICH Q5C, USP , and ISO 20933. Its 20 m² shelf area enables processing of up to 42,900 vials (Ø22 mm), making it suitable for clinical trial material production and commercial-scale cGMP manufacturing.

Key Features

• Shelf Pre-Freezing Capability: Uniform pre-freezing directly on shelves eliminates reliance on external ultra-low temperature freezers, reducing contamination risk and process variability.
• Programmable Process Control System: Fully customizable lyo cycles—from freezing through primary and secondary drying to final backfill—with up to 2000 user-defined or factory-standard protocols stored internally.
• Advanced Vacuum Regulation: Dynamic pressure control during both freezing and drying phases prevents melt-back, boil-over, and vial breakage; supports optimal mass transfer and drying kinetics.
• Pulse Backfill System: Three-speed inert gas (N₂ or argon) reintroduction—slow, medium, or fast—minimizes particle displacement and preserves cake morphology for sensitive biopharmaceuticals and powdered APIs.
• Real-Time Monitoring & Data Acquisition: 50 ms sampling frequency for shelf temperature, product temperature (via optional Pt100 probes), chamber pressure, and cold trap temperature; all data timestamped and traceable.
• GMP-Grade Construction: Chamber fabricated per ASME BPVC Section VIII Div. 1 and PED 2014/68/EU; internal surfaces mirror-polished (Ra ≤ 0.4 µm); full-radius corners and sloped floor for complete CIP/SIP drainage.
• Integrated Safety Architecture: Triple overpressure protection, interlocked door seals, helium-leak-tested vacuum piping (≤1×10⁻⁹ mbar·L/s), and redundant thermal fusing across all heating circuits.

Sample Compatibility & Compliance

The LYO-20 accommodates a wide range of sample formats—including serum vials (Ø13–Ø32 mm), trays, and custom containers—across pharmaceutical, biotech, nutraceutical, and diagnostic applications. Its design meets critical regulatory requirements: FDA 21 CFR Part 11 compliance for electronic records and signatures (audit trail enabled, role-based access control, non-erasable logs); EU Annex 11 alignment for computerized system validation; and full compatibility with GMP documentation workflows. The chamber withstands operating pressures from −0.15 MPa to +0.5 MPa, supporting both vacuum-assisted drying and pressurized SIP cycles. Optional co-located eutectic point measurement and residual moisture analysis interfaces allow seamless integration into quality-by-design (QbD) frameworks.

Software & Data Management

The embedded industrial HMI features a 15.6″ capacitive touchscreen with intuitive icon-driven navigation—requiring no operator manual for routine operation. All process parameters are logged in binary and CSV formats with SHA-256 checksum integrity verification. Remote monitoring is supported via Ethernet (TCP/IP) up to 1.5 km without repeaters, enabling centralized plant SCADA integration. The PC-based supervisory software provides real-time visualization, historical curve replay (shelf temp vs. time, pressure vs. time), deviation alerting, and exportable PDF reports compliant with ALCOA+ principles. Calibration logs for temperature sensors and capacitance manometers are digitally archived with user ID, timestamp, and reference standard traceability.

Applications

• Pharmaceutical Manufacturing: Terminal sterilization-compatible lyophilization of monoclonal antibodies, vaccines, and sterile injectables under cGMP conditions.
• Biotechnology R&D: Scale-up of lyo cycles from lab-scale (LYO-1/2) to pilot (LYO-10) and production (LYO-20/25) systems using identical control logic and thermal profiles.
• Clinical Supply Chain: Reliable production of Phase II/III clinical trial materials with full process traceability and batch record generation.
• Diagnostics & Reagents: Stabilization of enzyme conjugates, PCR master mixes, and lateral flow assay components without activity loss.
• Food & Nutraceuticals: High-throughput dehydration of probiotics, botanical extracts, and functional proteins while preserving heat-labile compounds.

FAQ

Is the LYO-20 qualified for FDA-regulated commercial manufacturing?
Yes—the system is supplied with IQ/OQ documentation templates, complies with 21 CFR Part 11, and supports full validation including DQ, IQ, OQ, and PQ protocols.
