Overview
The CZGY LHP-1500 Temperature and Humidity Controlled Incubator is an engineered environmental simulation platform designed for long-term stability testing, accelerated aging studies, and controlled-condition biological culture in regulated laboratory and industrial settings. It operates on a balanced air-jacketed heating and compressor-based refrigeration principle, coupled with precision humidity regulation via external auto-fill humidification. The system maintains stable thermal and hygroscopic conditions across its 1500 L working volume—critical for applications requiring strict adherence to ICH Q1A(R3), ISO 18416, ASTM D4332, and USP environmental test protocols. Its dual-door architecture, stainless steel interior, and corrosion-resistant exterior ensure structural integrity and contamination control over extended operational cycles. The incubator supports both constant-value and multi-segment programmable operation, enabling precise replication of real-world storage or stress conditions for pharmaceuticals, medical devices, food packaging, textiles, and polymer-based materials.
Key Features
- 7-inch full-color touchscreen interface with intuitive bilingual (English/Chinese) navigation, supporting both constant-setpoint and multi-step program modes
- Danfoss hermetic compressor integrated with electronic expansion valve for dynamic refrigerant flow control, ensuring consistent cooling performance and extended service life under continuous duty
- Balanced temperature–humidity regulation using PT100 platinum resistance thermometers and imported anti-condensation capacitive RH sensors, minimizing drift and hysteresis
- External 15 L humidification reservoir with automatic water intake, low-water cutoff, and dry-run protection—eliminating manual refilling during unattended operation
- Air-jacketed heating system with distributed 1800 W output and ten independent circulation fans (21 W each) for uniform airflow and minimized thermal gradients (±1.5°C uniformity)
- Four adjustable stainless steel shelves with reinforced load capacity, compatible with standard ISO/IEC 17025-compliant labware and multi-tier sample racks
- Triple-level user authentication (Operator / Supervisor / Administrator) with timestamped audit trail logging compliant with FDA 21 CFR Part 11 requirements for electronic records
- Real-time data acquisition and local storage via internal memory, with export capability to USB flash drives in CSV format for traceable post-processing
Sample Compatibility & Compliance
The LHP-1500 accommodates a broad spectrum of sample formats—including vials, Petri dishes, flasks, blister packs, pouches, and bulk material trays—within its 1500 × 770 × 1300 mm internal chamber. Its stainless steel interior and smooth-welded corners facilitate cleaning validation per GMP Annex 1 and ISO 14644-1 Class 7 cleanroom maintenance standards. The unit complies with electromagnetic compatibility (EMC) per IEC 61326-1 and safety requirements under IEC 61010-1. Its temperature and humidity control performance meets the reproducibility criteria specified in ISO 17025:2017 Clause 7.8.2 for environmental test equipment used in accredited laboratories. Optional IQ/OQ documentation packages are available upon request to support qualification under GLP and GMP frameworks.
Software & Data Management
The embedded control firmware supports up to five independent programs, each comprising up to 100 segments with definable ramp rates, dwell times (0–9999 minutes/hours), and setpoint transitions. All operational parameters—including actual vs. setpoint temperature/humidity, fan speed, compressor status, and humidifier activity—are logged at user-configurable intervals (1 s to 60 min). Data export via USB enables integration with LIMS platforms or statistical process control (SPC) software such as JMP or Minitab. The system retains all active settings and runtime history after power interruption and resumes operation automatically upon restoration, preserving experimental continuity. Audit trail entries include operator ID, timestamp, parameter change, and reason code—fully traceable for regulatory review.
Applications
- Pharmaceutical stability testing per ICH Q1 guidelines (long-term, intermediate, and accelerated conditions)
- Medical device packaging validation (ASTM F1980, ISO 11607-1)
- Food shelf-life modeling and moisture migration analysis
- Polymer degradation kinetics under combined thermal–hygric stress
- Microbial growth inhibition studies and fungal susceptibility screening
- Textile colorfastness and dimensional stability evaluation (ISO 139, AATCC 147)
- Electronics component reliability testing under high-humidity environments (JEDEC JESD22-A101)
FAQ
What is the maximum allowable ambient temperature for continuous operation?
The unit is rated for ambient temperatures up to 30°C at 60% RH. Operation above this threshold may reduce cooling efficiency and require derating per manufacturer’s technical bulletin.
Does the LHP-1500 support remote monitoring or network connectivity?
Standard configuration includes local touchscreen control and USB data export only. RS-485 Modbus RTU interface is available as an optional upgrade for integration into building management systems (BMS) or SCADA networks.
Can the internal lighting be disabled during dark-cycle experiments?
Yes—the 15 W LED illumination circuit is independently switchable via the touchscreen interface and can be scheduled or manually deactivated without affecting thermal or humidity control.
Is calibration certification included with delivery?
A factory-issued calibration report (traceable to NIM, China) covering temperature and humidity sensors at three points (25°C/60%RH, 40°C/75%RH, 55°C/85%RH) is provided. UKAS or NIST-traceable third-party calibration is available as a value-added service.
What maintenance intervals are recommended for optimal performance?
Compressor oil inspection every 24 months, humidifier tank cleaning weekly, and sensor verification annually—or per ISO/IEC 17025 internal quality schedule—are advised. Full preventive maintenance kits and service contracts are offered by CZGY authorized partners.
