AnYuJie HWS-1500 Large-Capacity Temperature and Humidity Controlled Incubator

Overview

The AnYuJie HWS-1500 is a large-capacity, microprocessor-controlled temperature and humidity incubator engineered for long-term, stable environmental simulation in life science research and industrial quality assurance. It operates on the principle of air-jacketed thermal regulation combined with ultrasonic humidification—enabling precise, independent control of temperature and relative humidity across a broad operational envelope. Unlike water-jacketed systems, the air-jacketed design offers rapid thermal response while maintaining robust stability under variable ambient conditions. The unit is purpose-built for applications requiring reproducible, GxP-aligned environmental conditioning—including BOD incubation, seed germination trials, microbial culture maintenance, pharmaceutical stability testing (per ICH Q1 guidelines), and environmental stress screening of biological samples. Its 1500 L internal chamber accommodates high-throughput experimental setups, multi-tier shelving configurations, and integrated sensor arrays without compromising spatial uniformity.

Key Features

• Air-jacketed heating architecture with dual-stage PID temperature control ensures fast ramp-up and minimal overshoot, optimized for routine laboratory cycling and extended incubation protocols.
• Compressor-based refrigeration system (original Tecumseh/Tecumseh-equivalent hermetic compressor) includes high/low pressure protection circuits and delayed startup logic to extend service life and prevent thermal shock during power recovery.
• Ultrasonic humidification module with external reservoir enables continuous, particle-free moisture delivery—eliminating mineral deposits, condensation pooling, and localized RH gradients common in steam-based systems.
• Dual-door construction with magnetic gasket seal and low-emissivity double-glazed observation window minimizes thermal bridging and maintains optical clarity under high-humidity operation.
• Stainless steel interior chamber (AISI 304 grade) with rear-mounted forced-air circulation ductwork ensures uniform airflow distribution and eliminates dead zones—validated per ISO 15197 Annex D methodology for spatial homogeneity.
• Independent overtemperature cutoff and sensor fault detection circuitry provide hardware-level safety redundancy, compliant with IEC 61010-1 Class II requirements for laboratory equipment.

Sample Compatibility & Compliance

The HWS-1500 supports diverse sample formats including Petri dishes, multiwell plates, flasks, bioreactor vessels, and botanical growth trays—compatible with standard laboratory shelving (max load: 25 kg per shelf). Its temperature and humidity profiles meet the operational prerequisites for ASTM D5208 (lightfastness testing), USP (pharmaceutical storage conditions), and EN 12460-3 (wood preservation testing). While not certified to full GLP/GMP validation standards out-of-the-box, the unit’s architecture supports IQ/OQ documentation and can be configured for 21 CFR Part 11-compliant data logging when paired with optional external audit-trail software modules. Humidity control performance has been verified across 40–95 %RH at 25 °C and 37 °C setpoints using NIST-traceable hygrometers.

Software & Data Management

The embedded microcontroller features a 4.3-inch TFT LCD interface with real-time graphing of temperature and RH trends (sampling interval: 30 s). All setpoints, alarms, and event logs (e.g., door openings, compressor cycles, humidifier activation) are timestamped and stored internally for up to 30 days. Optional RS-485 Modbus RTU or Ethernet TCP/IP connectivity enables integration into centralized lab management systems (LIMS) or SCADA platforms. Raw data export is supported via USB flash drive in CSV format—structured to align with ISO/IEC 17025 clause 7.5.2 requirements for measurement traceability and record retention. Firmware updates are performed via secure signed binaries to prevent unauthorized modification.

Applications

• Biochemical oxygen demand (BOD₅) analysis per APHA Standard Methods 5210B, maintaining strict 20 ± 0.5 °C and 90–95 %RH conditions for 5-day incubation.
• Plant tissue culture and seed viability studies requiring diurnal temperature cycling (programmable via external timer input).
• Microbial challenge testing of medical device packaging per ISO 11607-2, simulating accelerated aging at 55 °C/60 %RH.
• Environmental acclimation of aquatic species prior to toxicity assays (OECD 203), where stable O₂-saturated water baths require synchronized ambient chamber control.
• Long-term stability assessment of diagnostic reagents and monoclonal antibody formulations under ICH Q5C recommended storage conditions.

FAQ

What is the maximum allowable ambient temperature for continuous operation?
The unit is rated for continuous use in environments up to 32 °C ambient with ≤70 %RH. Performance validation data confirms stable 50 °C/95 %RH operation at 25 °C ambient; higher ambient temperatures may reduce achievable RH ceiling.
Can the incubator maintain humidity below 40 %RH?
No—the ultrasonic humidifier is not designed for active dehumidification. For sub-40 %RH applications, an external desiccant dryer or dedicated low-RH chamber is required.
Is stainless steel shelving included as standard?
Yes—three adjustable AISI 304 shelves are supplied with load-rated support brackets. Additional shelves or wire mesh inserts are available as accessories.
Does the controller support programmable ramp-and-soak profiles?
The base firmware supports single-setpoint control only. Multi-step programming requires optional firmware upgrade and external PC configuration tool.
What calibration documentation is provided with shipment?
Each unit ships with a factory calibration certificate covering temperature (at 25 °C and 37 °C) and humidity (at 60 %RH and 85 %RH), traceable to national metrology institutes via third-party accredited labs.
