IRM B75 Advanced Vertical Autoclave with Multi-Level Access Control and Zero-Steam Emission Technology

Overview

The IRM B75 Advanced Vertical Autoclave is an engineered Class B steam sterilizer designed for regulated laboratory, pharmaceutical, and biotechnology environments requiring validated, repeatable, and traceable sterilization cycles. Operating on saturated steam under pressure (up to 0.3 MPa), it achieves sterilization temperatures up to 141 °C—exceeding standard EN 285 and ISO 17665-1 requirements for porous load sterilization. Its fully jacketed stainless-steel chamber (SUS304) ensures uniform thermal distribution and mechanical durability, while the integrated iSmart dual-controller architecture (PID + PLC) delivers precise temperature and pressure regulation within ±0.3 °C and ±0.01 MPa stability over full cycle duration. Unlike conventional gravity-displacement autoclaves, the B75 employs a vacuum-assisted pre-sterilization air removal sequence followed by rapid steam penetration—enabling reliable sterilization of wrapped instruments, porous materials, and liquid media in accordance with ISO 11140 and USP . The system complies with key regulatory expectations for data integrity, including ALCOA+ principles, and supports audit-ready documentation for GMP, FDA 21 CFR Part 11, and EU Annex 11 compliance when paired with optional certified printer or data logger modules.

Key Features

• Zero-steam-emission internal condensation system: All process steam is condensed and cooled internally; no external venting required—ideal for confined lab spaces and HVAC-sensitive facilities.
• Multi-level user access control: Configurable administrator, operator, and technician roles with password-protected parameter editing, cycle initiation, and data export permissions—enabling role-based accountability per GMP Annex 11 and ISO/IEC 17025.
• iSpeed rapid cooling module: Reduces post-cycle cooldown time to approximately 6 minutes via active chamber heat exchange—minimizing throughput bottlenecks without compromising sterility assurance.
• Dual safety architecture: Combines active safeguards (real-time water level monitoring, dual independent overtemperature cut-offs, SSR failure detection) and passive protections (mechanical pressure relief valve, door interlock with position sensing, fail-safe door locking at >40 °C).
• 7-inch high-resolution color touchscreen interface: Intuitive graphical workflow navigation with context-sensitive prompts, real-time cycle status visualization, and one-touch recall of last executed program.
• Eight preconfigured sterilization modes: Including media sterilization, instrument sterilization, solid load, liquid load, waste decontamination, keep-warm, dissolution, and vessel preheating—with independent time/temperature setpoints per phase.
• Three programmable exhaust strategies: Full exhaust, pulsed exhaust, and no-exhaust (for heat-labile liquids), all automatically sequenced and logged with timestamped event records.

Sample Compatibility & Compliance

The B75 accommodates a broad range of sterilizable loads—including wrapped surgical kits, glassware, stainless-steel tools, culture media (up to 10 L per vessel), and biohazardous waste bags—within its 75 L SUS304 chamber (Ø400 × 583 mm). Its vacuum-assisted cycle profile meets EN 13060 Class B requirements for steam penetration into porous and hollow loads. All electronic components conform to IEC 61010-1 safety standards; pressure vessel design adheres to GB/T 150 (China) and ASME Section VIII Div. 1 equivalency protocols. The system supports validation per IQ/OQ/PQ protocols and includes built-in self-diagnostics for sensors, SSRs, door actuators, and pressure transducers—facilitating routine requalification and preventive maintenance scheduling.

Software & Data Management

The iSmart controller logs all critical process parameters (chamber temperature, jacket temperature, pressure, cycle phase, door status, error codes) with millisecond-level timestamps. Audit trails are immutable and retain ≥10,000 complete cycles locally. Optional RS485/USB interfaces enable integration with LIMS or MES platforms. When equipped with the certified thermal printer or 4–20 mA analog recorder, the system generates 21 CFR Part 11–compliant hardcopy records—including operator ID, cycle ID, start/stop times, peak temperature/pressure, and deviation flags. Electronic signatures, electronic record retention policies, and secure backup export (CSV/Excel) are supported through firmware version 3.2.1 or later.

Applications

• Pharmaceutical QC labs: Sterilization of media, buffers, and glassware used in microbial limit testing (USP , ) and sterility testing (USP ).
• Biotech R&D facilities: Decontamination of single-use bioreactor components, filtration housings, and sampling manifolds.
• Hospital central sterile supply departments (CSSD): Processing of reusable surgical instruments and implantable device packaging.
• Academic and contract research organizations: Validated sterilization of agar plates, petri dishes, and fermentation vessels under GLP conditions.
• Veterinary diagnostics: High-throughput sterilization of swab transport media and PCR consumables prior to nucleic acid extraction.

FAQ

Does the B75 support automated validation and qualification documentation?
Yes—the system stores raw sensor data, cycle logs, and alarm history internally and exports structured CSV files compatible with third-party validation software (e.g., ValGenesis, TrackWise). Optional IQ/OQ templates aligned with ISO 13485 and FDA guidance are available upon request.
Can the B75 be integrated into a facility’s Building Management System (BMS)?
Via Modbus RTU over RS485, the controller provides real-time status signals (running/idle/error), chamber temperature, pressure, and door open/closed state—enabling centralized monitoring without proprietary gateways.
What is the warranty coverage and service response time?
IRM provides a 24-month parts-and-labor warranty from commissioning date. Field service engineers respond within 72 business hours for critical sterilization downtime events in Tier-1 cities across China, with remote diagnostics support available globally.
Is the stainless-steel chamber passivated and electropolished per ASTM A967?
Yes—the interior surface undergoes citric acid passivation and electropolishing to Ra ≤ 0.4 µm finish, verified by surface roughness measurement and ferroxyl testing per ASTM A380.
How is data integrity ensured during power interruption?
The controller retains all active cycle data in non-volatile memory and resumes logging upon power restoration. Critical alarms trigger immediate local audio-visual alerts and lockout until acknowledged by authorized personnel.
