CZGY HWS-1000 Temperature and Humidity Controlled Incubator

Overview

The CZGY HWS-1000 Temperature and Humidity Controlled Incubator is an engineered environmental simulation platform designed for long-term, high-stability operation in pharmaceutical stability testing, accelerated aging studies, biotechnology research, and materials science applications. It operates on a dual-control principle—air-jacketed heating combined with compressor-based cooling and external reservoir humidification—to achieve precise, independent regulation of temperature and relative humidity across a broad operational envelope (5–65°C / 20–95% RH). Unlike single-loop systems, the HWS-1000 employs a balanced air-flow modulation strategy: heated and cooled air is dynamically mixed and distributed via a rear-mounted centrifugal fan system, while humidity is introduced through a dedicated vaporization chamber fed by an auto-refill water reservoir. This architecture minimizes thermal lag and condensation risk, ensuring low-hysteresis response and stable setpoint maintenance—even during extended low-humidity operation at elevated temperatures (e.g., 65°C / 20% RH), a critical requirement for ICH Q1A(R2) stability protocols.

Key Features

• 7-inch full-color TFT touchscreen interface with 800 × 480 resolution, supporting both English and Chinese language modes and intuitive drag-and-drop program editing
• Dual-stage compressor cooling system with imported electronic expansion valve for fine-grained refrigerant flow control and continuous-duty reliability
• External humidification module featuring automatic water level detection, solenoid-controlled refill, and dry-run prevention circuitry
• Stainless steel 304 interior chamber (1200 × 695 × 1200 mm) with seamless welding, rounded corners, and non-porous surface finish for ease of decontamination
• Double-door viewing structure: inner tempered glass door + outer insulated observation window with anti-fog coating
• Five-tier adjustable shelving system with load-rated stainless steel trays (max. 15 kg per shelf)
• Real-time data logging via embedded SD card or USB drive; optional Ethernet connectivity enables remote monitoring and centralized lab management integration
• Independent over-temperature cutoff circuit with mechanical backup limiter, compliant with IEC 61000-4-2/4-4 immunity standards

Sample Compatibility & Compliance

The HWS-1000 accommodates a wide range of sample formats—including stacked stability chambers, multi-well plates, vials, blister packs, textile swatches, and packaged food specimens—within its 1000 L working volume. Its uniform airflow design ensures ±1.5°C temperature homogeneity and ±5% RH humidity consistency across the entire chamber, validated per ISO 16770:2017 (Environmental testing — Guidance on validation of environmental test chambers). The unit meets structural and electrical safety requirements under GB 4793.1–2019 (Safety requirements for electrical equipment for measurement, control, and laboratory use) and is compatible with Good Laboratory Practice (GLP) and Good Manufacturing Practice (GMP) workflows when paired with validated data acquisition software. Optional 21 CFR Part 11-compliant audit trail modules are available for regulated pharmaceutical environments.

Software & Data Management

The onboard controller supports local programming of up to five distinct test profiles, each comprising up to 100 time-temperature-humidity segments with durations configurable in minutes or hours. All operational parameters—including setpoints, actual readings, alarm events, and power status—are timestamped and stored internally. Data export is supported via USB mass storage mode (CSV format) or real-time streaming over TCP/IP using Modbus RTU/TCP protocol. When connected to a networked laboratory information management system (LIMS), the incubator can feed raw sensor outputs (PT100 temperature probes, capacitive RH sensors) directly into centralized databases. Optional firmware upgrades enable CSV-to-Excel conversion, statistical process control (SPC) charting, and automated deviation reporting aligned with Annex 11 and ALCOA+ data integrity principles.

Applications

• ICH-guided long-term and accelerated stability testing of APIs and finished drug products
• Accelerated aging studies for medical device packaging (ISO 11607, ASTM F1980)
• Moisture sorption isotherm determination in food science and polymer research
• Plant growth physiology experiments requiring controlled diurnal cycles
• Textile and leather durability assessment under cyclic humidity stress
• Material degradation analysis of adhesives, coatings, and composite laminates
• Microbial culture support where ambient humidity impacts colony morphology and metabolic rate

FAQ

What is the minimum achievable humidity at 65°C?
At 65°C, the HWS-1000 maintains stable operation down to 20% RH with ±5% RH accuracy, verified under continuous 72-hour hold conditions.
Does the unit support remote monitoring via Ethernet?
Yes—RS485 and Ethernet interfaces are standard; IP address, subnet mask, and gateway settings are configurable via the touchscreen UI.
Is the internal chamber fully drainable for cleaning?
The sloped stainless steel floor features a central drainage port with quick-connect fitting, enabling full chamber evacuation without disassembly.
Can the incubator operate unattended for extended periods?
With its compressor-rated duty cycle, electronic expansion valve, and redundant thermal protection, the HWS-1000 is certified for uninterrupted 24/7 operation up to 30 days.
Are calibration certificates included with shipment?
NIST-traceable factory calibration reports for temperature and humidity sensors are provided; on-site IQ/OQ/PQ validation support is available upon request.
