Zealway GR60SA Vertical Fully Automatic High-Pressure Steam Sterilizer

Overview

The Zealway GR60SA is a vertical, fully automatic high-pressure steam sterilizer engineered for precision, reliability, and regulatory compliance in academic laboratories, clinical microbiology units, pharmaceutical QC labs, and biomedical research facilities. It operates on the validated principle of saturated steam sterilization—leveraging controlled temperature (105–138 °C) and pressure (up to 0.30 MPa working, 0.42 MPa design) to achieve microbial inactivation through protein denaturation and nucleic acid disruption. The unit conforms to YY 1007–2010, the Chinese national standard for vertical steam sterilizers, and its structural integrity, safety interlocks, and process repeatability support alignment with broader international expectations—including ISO 17665-1 (sterilization of health care products), EN 285 (large steam sterilizers), and GLP/GMP operational frameworks.

Key Features

• Intelligent Microprocessor Control System: Equipped with the “Inspiration” high-speed embedded microcomputer platform, enabling full automation of cycle phases—pre-vacuum air removal, heating, sterilization hold, exhaust, and optional drying—without manual intervention.
• Saturated Steam Environment Assurance: Real-time cold-air purge monitoring ensures complete air evacuation prior to sterilization, maintaining ≥97% steam saturation—a critical parameter for thermal lethality consistency per ISO 17665-1 Annex C.
• Multi-Level Security Architecture: Integrated dual-pressure sensors, overtemperature cutoffs, dry-run protection, overcurrent/short-circuit detection, and door-lock interlocks provide redundant mechanical and electronic safeguards compliant with IEC 61010-1 requirements.
• Configurable Exhaust Profiles: Six programmable exhaust modes allow precise control of post-cycle depressurization rate—critical for heat-labile media (e.g., agar, culture broths) to prevent boil-over or container rupture.
• Automated Chamber Maintenance: Optional auto-cleaning and scheduled rinse cycles reduce biofilm accumulation and mineral scaling, extending chamber service life and supporting routine validation readiness.
• Material Options & Engineering Enhancements: Standard SUS304 stainless steel construction; optional upgrade to medical-grade SUS316L for enhanced corrosion resistance in high-chloride or saline-rich environments—particularly relevant for sterilizing surgical instruments or saline-based reagents.

Sample Compatibility & Compliance

The GR60SA accommodates diverse load types—including wrapped instruments, porous textiles (linen packs), unwrapped solids, liquids in vented containers, rubber items, and regulated biohazard waste—via ten preconfigured, user-editable sterilization programs. Each cycle includes configurable time–temperature profiles and pressure ramping parameters, enabling adaptation to USP , ISO 11134, and CLSI M22-A3 guidelines. The system supports traceable record retention (cycle logs, alarms, operator IDs) required under FDA 21 CFR Part 11 when paired with optional LIMIS or SCADA integration. All safety valves, pressure transducers, and temperature probes are calibrated per ISO/IEC 17025-accredited procedures, and documentation packages include Factory Acceptance Test (FAT) reports and IQ/OQ templates.

Software & Data Management

Local operation is managed via intuitive touch interface (optional LCD panel); remote supervision is enabled through Zealway’s secure LIMIS-compatible API or SCADA-ready Modbus TCP protocol. Cycle data—including chamber temperature/pressure curves, phase timestamps, alarm events, and user authentication logs—are timestamped, digitally signed, and exportable in CSV or PDF format. Audit trails meet ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available), facilitating internal audits and regulatory inspections. Firmware updates maintain backward compatibility and include version-controlled change logs aligned with ICH Q5A and GAMP 5 software lifecycle standards.

Applications

• Terminal sterilization of reusable surgical kits and dental handpieces in hospital central sterile supply departments (CSSD)
• Media preparation and instrument decontamination in university microbiology teaching labs
• Batch sterilization of agar plates, broth tubes, and buffer solutions in biotech R&D settings
• Validation support for ISO 13485-certified medical device manufacturers
• Waste decontamination in BSL-2 containment laboratories handling non-viable biological agents
• Pharmaceutical excipient and packaging component sterilization under cGMP Annex 1 considerations

FAQ

What regulatory standards does the GR60SA comply with?
It meets YY 1007–2010 (China), incorporates design elements consistent with EN 285 and ISO 17665-1, and supports documentation workflows compatible with FDA 21 CFR Part 11, EU Annex 11, and ISO 13485 quality management systems.
Can the GR60SA be integrated into a laboratory information management system (LIMS)?
Yes—via optional LIMIS interface or SCADA connectivity using Modbus TCP or RS485 protocols, enabling real-time status monitoring and automated data ingestion into enterprise platforms.
Is validation support provided with the instrument?
Zealway supplies IQ/OQ protocol templates, FAT documentation, calibration certificates for critical sensors, and a comprehensive user manual with preventive maintenance schedules—all aligned with ISO/IEC 17025 and GAMP 5 best practices.
What is the maximum allowable load volume for liquid sterilization cycles?
For optimal heat penetration and prevention of boil-over, the recommended maximum fill level is 70% of total chamber volume (i.e., ≤42 L for the 60 L chamber), with containers arranged to permit unobstructed steam circulation.
Does the unit support steam quality monitoring per HTM 2031 or EN 285?
While the GR60SA does not include built-in steam purity analyzers, its saturated steam generation architecture, condensate management system (zero-emission condenser), and cold-air purge verification align with core steam quality prerequisites defined in those standards. Third-party steam quality testing remains the responsibility of the end-user’s validation team.
