AnYuJie HWS-600 Large-Capacity Temperature and Humidity Controlled Incubator

Overview

The AnYuJie HWS-600 Large-Capacity Temperature and Humidity Controlled Incubator is an engineered environmental simulation system designed for long-term, stable maintenance of precise thermal and hygric conditions across life science laboratories. It operates on a dual-control principle: air-jacketed heating ensures rapid, uniform thermal response, while compressor-based refrigeration enables active cooling within the full operational temperature span. Humidity is regulated via ultrasonic humidification—providing consistent vapor generation without localized condensation or mineral deposition—and supported by a high-capacity external water reservoir to minimize intervention during extended experiments. The chamber’s forced-air circulation system, constructed with electropolished stainless steel ducts and optimized fan geometry, achieves ±1 °C temperature uniformity and ±5 %RH humidity accuracy throughout its 600 L working volume. This architecture meets functional requirements for BOD incubation, seed germination trials, microbial culture stabilization, and environmental stress testing under controlled ambient parameters.

Key Features

• Air-jacketed heating system with independent PID control for rapid thermal equilibration and minimal overshoot
• Original Tecumseh (France) hermetic compressor with dual-stage pressure protection and delayed startup logic to extend service life
• Ultrasonic humidifier integrated with external water tank—eliminates boiling elements and reduces maintenance frequency
• Dual-door design with magnetic gasket seal and low-emissivity double-glazed inner door—reduces heat loss and improves energy efficiency
• Stainless steel internal chamber and circulation ductwork—resistant to corrosion from repeated sterilization cycles and organic vapors
• Real-time overtemperature and sensor fault detection with automatic power cutoff and visual/audible alarm
• Intelligent defrost management that prevents ice accumulation in refrigeration circuitry during low-temperature operation

Sample Compatibility & Compliance

The HWS-600 accommodates standard ISO-compliant stacking configurations: up to eight 300 mm × 300 mm × 150 mm stackable culture trays or four 500 mL Erlenmeyer flasks per shelf level. Its interior dimensions (1100 × 520 × 820 mm W×D×H) support multi-tiered sample arrays without compromising airflow integrity. The unit complies with IEC 61010-1:2010 for laboratory equipment safety and conforms to EN 60335-2-86 for household and similar electrical appliances used in scientific environments. While not certified for GMP manufacturing environments, it supports GLP-aligned workflows through traceable parameter logging, manual calibration verification points, and documented maintenance intervals. Humidity control performance aligns with ASTM D4332–22 for conditioning procedures in biological material storage.

Software & Data Management

The incubator features a built-in 7-inch capacitive touchscreen interface with embedded firmware supporting real-time monitoring of temperature, relative humidity, runtime, and error codes. All setpoints and actual values are logged at user-configurable intervals (1–60 minutes) to internal non-volatile memory (≥30 days at 10-min resolution). Data export is available via USB 2.0 port in CSV format for integration into LIMS or Excel-based QA review. Optional RS-485 Modbus RTU interface enables centralized building management system (BMS) integration. Audit trail functionality records operator login events, parameter changes, and alarm acknowledgments—supporting basic 21 CFR Part 11 readiness when paired with institutional electronic signature policies.

Applications

• Biochemical Oxygen Demand (BOD) testing per APHA Standard Methods 5210B and ISO 5815-1
• Plant tissue culture and seed germination studies requiring diurnal humidity cycling
• Microbial growth kinetics under defined hygrothermal stress (e.g., Aspergillus spp. sporulation assays)
• Long-duration stability testing of diagnostic reagents and vaccine formulations
• Environmental simulation for aquatic toxicology (e.g., OECD 202 algal growth inhibition)
• Pre-conditioning of polymer-based medical device packaging prior to accelerated aging

FAQ

What is the recommended maintenance schedule for the ultrasonic humidifier?**
Clean the transducer plate weekly with deionized water and soft lint-free cloth; replace the external water tank filter every 6 months or after 500 operating hours.
Can the HWS-600 operate continuously at 5 °C with 95 %RH?**
Yes—its compressor and humidification subsystems are thermally coordinated to sustain this condition; however, periodic manual drainage of the condensate pan is required to prevent overflow.
Is remote monitoring supported out-of-the-box?**
No native Ethernet or Wi-Fi module is included; remote access requires third-party IoT gateway integration via the RS-485 interface.
Does the unit meet UL or CSA certification requirements?**
It carries CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD); UL/CSA listing is not available but may be pursued under contract for specific regional deployments.
How is temperature uniformity validated across the chamber volume?**
Uniformity is verified using nine NIST-traceable PT100 probes positioned per ISO 15265:2021 Annex B—three per horizontal plane (top/middle/bottom), each at center and corners.
