Overview
The HePu WS-200YDC Horizontal Autoclave is a fully automated, jacketed steam sterilizer engineered for reliable, repeatable terminal sterilization of heat- and moisture-stable materials in laboratory, pharmaceutical, clinical, and industrial settings. It operates on the principle of saturated steam under pressure—leveraging the high latent heat of condensation to achieve rapid, uniform thermal penetration into loads. At 134 °C and 0.22 MPa, the unit meets internationally recognized sterilization cycles (e.g., EN 285, ISO 17665-1, and FDA-recommended parameters for porous load sterilization), ensuring microbial lethality (≥12-log reduction of Geobacillus stearothermophilus spores) when validated protocols are applied. Its horizontal cylindrical chamber design supports efficient loading of large or irregular items—including surgical instrument trays, glassware, textile packs, culture media bottles, and food samples—while maintaining strict compliance with GLP, GMP, and ISO 13485 quality system requirements.
Key Features
- Double-walled, jacketed stainless steel construction (AISI 304) with vacuum-formed insulation layer filled with high-efficiency glass wool—minimizing heat loss and improving energy efficiency.
- Integrated safety interlock system compliant with EN 61010-1 and PED 2014/68/EU: door remains mechanically locked until chamber pressure drops below 0.027 MPa; heating and steam admission are disabled if door is unlatched or water level is insufficient.
- Automatic air removal via programmable pre-vacuum and dynamic steam pulsing—ensuring complete air displacement and eliminating cold spots for consistent thermal distribution (≤2 °C deviation across chamber volume).
- Microprocessor-based control panel with real-time graphical display of temperature, pressure, time, and phase status (pre-heat, sterilize, dry, exhaust); all critical process parameters logged with timestamp and user ID.
- Redundant safety mechanisms: dual independent temperature sensors, overpressure relief valve (set at 0.24 MPa), leakage current protection, dry-run prevention, and automatic drain activation upon fault detection.
- Programmable multi-step cycles—including pre-vacuum, sterilization, post-sterilization drying, and gravity-assisted exhaust—with adjustable dwell times (1–60 min each) and temperature setpoints (110–134 °C).
Sample Compatibility & Compliance
The WS-200YDC accommodates a broad range of load types: wrapped and unwrapped instruments, porous textiles, liquid media in vented containers, rubber tubing, and solid non-porous items. Chamber dimensions (Ø515 mm × 1000 mm) support standard ISO 15883-compliant tray configurations and allow vertical stacking of up to 4× 400 mm-high racks. All materials in contact with steam (chamber, door gasket, drain piping) are certified biocompatible and corrosion-resistant. The autoclave conforms to key regulatory frameworks including ISO 17665-1:2017 (moist heat sterilization), EN 285:2015 (large steam sterilizers), and supports validation documentation required for FDA 21 CFR Part 11 compliance when paired with audit-trail-enabled software.
Software & Data Management
The embedded controller records full-cycle data—including pressure, temperature, time, and alarm events—with internal storage for ≥10,000 cycles. Optional RS485/Modbus RTU or Ethernet interface enables integration with LIMS or central monitoring systems. Exportable CSV logs include cycle ID, operator code, start/end timestamps, maximum/minimum/mean chamber temperatures, and deviation flags—facilitating traceability, root cause analysis, and annual requalification per ISO 13485 Clause 7.5.2. Audit trail functionality captures all parameter modifications, user logins, and emergency stops, satisfying electronic record retention requirements under GxP environments.
Applications
This autoclave is routinely deployed in hospital central sterile supply departments (CSSD), university microbiology and cell culture labs, pharmaceutical R&D facilities, food safety testing laboratories, and biotech manufacturing sites. Typical use cases include: sterilization of surgical kits prior to packaging; depyrogenation of glass vials and stoppers; inactivation of biological waste (UN 3291); preparation of agar and broth media; and validation of sterilization processes for Class B medical devices (EN 13060). Its 0.2 m³ capacity and robust thermal recovery rate make it suitable for medium-throughput operations requiring batch consistency and regulatory defensibility.
FAQ
What is the maximum allowable working pressure and temperature?
The rated maximum operating pressure is 0.22 MPa at 134 °C, with overpressure protection activated at 0.24 MPa.
Does the unit support validation and qualification documentation?
Yes—the system provides raw process data logs compatible with IQ/OQ/PQ protocols and includes calibration-ready sensor ports for third-party thermocouple verification.
Is the autoclave suitable for sterilizing liquids?
Yes, provided containers are vented and loaded upright; the controller includes dedicated liquid-cycle profiles with slow exhaust to prevent boil-over.
How is door safety enforced during operation?
A mechanical lock engages automatically when chamber pressure exceeds 0.027 MPa; the door cannot be opened until pressure falls below this threshold and the system confirms safe temperature decay.
What power supply configuration is required?
A dedicated 380 V AC, 50 Hz, three-phase supply with 9 kW continuous rating and appropriate circuit protection (e.g., 25 A breaker) is mandatory.
