Compact Temperature and Humidity Controlled Chamber – OEM/ODM Manufacturer

Overview

The Compact Temperature and Humidity Controlled Chamber is an engineered environmental test system designed for precise, repeatable simulation of temperature and humidity conditions in constrained laboratory spaces. Based on dual-refrigeration and steam-humidification principles, it delivers stable thermal-hygrometric control across wide operational ranges—enabling accelerated stress testing, material stability evaluation, and qualification of electronic components, polymers, pharmaceutical packaging, and optoelectronic devices under defined climatic profiles. Its architecture integrates a high-efficiency cascade refrigeration circuit for sub-zero operation and a PID-controlled saturated steam generator for accurate RH modulation—both independently monitored and dynamically balanced via real-time feedback from calibrated Pt100 sensors and capacitive hygrometers.

Key Features

• Space-optimized footprint: Engineered for installation in confined labs or QC benches—minimum floor area requirement without compromising internal volume integrity.
• Large observation window with anti-fog heated double-glazed glass: Enables continuous visual monitoring of sample behavior during dynamic cycling without thermal leakage or condensation interference.
• Drawer-type water reservoir with high-capacity capacity: Supports extended uninterrupted humidity testing; facilitates rapid draining, cleaning, and maintenance without tooling or disassembly.
• Multi-layer safety architecture: Includes over-temperature cutoff, compressor high-pressure protection, phase failure detection, door interlock, and independent humidity over-limit alarm—ensuring both sample integrity and operator safety.
• Intuitive TEMI880 color LCD touchscreen controller: Supports up to 99 programmable segments per cycle, ramp/soak profiles, real-time trend logging, and USB data export—designed for GLP-compliant documentation workflows.
• Robust chamber construction: Interior chamber fabricated from electropolished SUS304 stainless steel for corrosion resistance and cleanability; outer enclosure available in either SUS304 or A3 steel with epoxy-powder coating for mechanical durability.

Sample Compatibility & Compliance

This chamber accommodates a broad range of sample types—including PCB assemblies, battery cells, medical device housings, adhesive tapes, and lyophilized vials—within its standard internal dimensions (customizable upon request). All models are factory-calibrated and verified per national metrological standards. The system complies with key Chinese national standards for environmental testing equipment: GB10589 (low-temperature test chambers), GB10592 (combined temperature/humidity chambers), GB11158 (high-temperature chambers), GB/T5170.2 (temperature performance verification), GB/T5170.5 (humidity performance verification), and GB2423 series (IEC 60068-2 equivalent) for environmental testing methods including Test A (cold), Test B (dry heat), and Test N (temperature change). While not certified to ISO/IEC 17025 or accredited to ISO 17025:2017, the chamber meets the technical prerequisites for use in GMP-aligned stability studies when operated within documented SOPs and routine calibration intervals.

Software & Data Management

The TEMI880 controller provides embedded data logging at user-selectable intervals (1–600 seconds), storing up to 100 cycles with timestamped temperature and humidity values. Data export is supported via USB flash drive in CSV format for post-processing in Excel or statistical analysis platforms. Optional RS485/Modbus RTU interface enables integration into centralized lab monitoring systems (e.g., LabWare LIMS or Siemens Desigo CC). Audit trail functionality includes operator login records, parameter modification logs, and alarm event timestamps—supporting basic 21 CFR Part 11 readiness when paired with organizational procedural controls. Firmware updates are performed locally via USB, ensuring long-term compatibility and traceable version control.

Applications

• Accelerated aging of polymer-based medical device packaging under ICH Q1A(R2) recommended conditions (e.g., 40 °C/75% RH).
• Thermal shock screening of surface-mount components per JEDEC JESD22-A104.
• Stability testing of active pharmaceutical ingredients (APIs) and finished dosage forms per USP <1151>.
• Environmental qualification of automotive ECUs per ISO 16750-4.
• Moisture absorption/desorption characterization of composite materials and printed circuit boards.
• Calibration verification of portable hygrometers and thermometers against NIST-traceable references.

FAQ

What is the actual temperature uniformity inside the working chamber during steady-state operation?
Uniformity is specified as ±0.5 °C across the usable volume under no-load, 25 °C ambient conditions—verified per GB/T5170.2 using nine-point sensor mapping.
Can this chamber perform rapid temperature transitions (e.g., 10 °C/min)?
No. Rated heating and cooling rates are 2.0–3.0 °C/min and 0.7–1.0 °C/min respectively—measured as air temperature change in empty chamber per GB2423.22. Actual sample response will vary based on mass, thermal mass, and mounting configuration.
Is the humidity system capable of operating below 30% RH?
Standard configuration supports 30–98% RH. Sub-30% RH operation (down to 5% RH) requires optional dehumidification module (e.g., desiccant wheel or deep-cooling coil), which must be specified at time of order.
Does the unit include calibration certificates with NIST traceability?
Factory calibration reports are provided with each shipment. NIST-traceable certification is available as an optional add-on service, performed by an ILAC-accredited third-party lab prior to delivery.
What are the facility requirements for installation?
Cooling water supply: 10–28 °C, 0.1–0.3 MPa pressure, ≥1.5 L/min flow rate. Electrical supply: 380 V ±5%, 50 Hz, 3P+N+G (220 V variants available). Ambient temperature: 25 °C ±6 °C, non-condensing environment.
