Overview
The Jianhu JH-ATL Series High-Low Temperature Environmental Test Chamber is an engineered solution designed specifically for aerospace qualification testing under extreme thermal conditions. Based on forced-air convection with dual-stage compressor refrigeration and PID-controlled resistive heating, the chamber delivers repeatable, traceable thermal profiles across a wide operational range (−70 °C to +150 °C). Its architecture adheres to principles defined in MIL-STD-810H, RTCA DO-160G Section 4 (Temperature), and ISO 16750-4 for automotive and aerospace environmental stress screening—making it suitable for component-level validation, subsystem thermal cycling, and full-system environmental simulation. Unlike general-purpose environmental chambers, the JH-ATL Series integrates structural rigidity, hermetic sealing integrity, and real-time thermal mapping capabilities to support GLP-compliant test documentation and audit-ready data trails.
Key Features
- Explosion-proof construction certified per IEC 60079-1 and GB 3836.1–2010, enabling safe operation with volatile materials or oxygen-enriched test environments.
- High-strength alloy steel chamber walls with multi-layer insulation (vacuum-insulated panels optional), minimizing thermal bridging and ensuring long-term dimensional stability during repeated thermal cycling.
- Advanced dual-loop PID control system with redundant platinum resistance temperature sensors (PT100 Class A), delivering temperature fluctuation ≤ ±0.5 °C and uniformity ≤ ±2.0 °C across the working volume.
- Multi-segment programmable temperature profiles supporting up to 99 cycles, ramp rates from 0.5 °C/min to 10 °C/min, and soak dwell times configurable to 999 hours.
- Integrated mechanical vibration isolation mounts and reinforced floor anchoring points to maintain thermal stability during concurrent mechanical stress testing (e.g., when interfaced with shaker tables).
- Real-time thermal mapping interface compatible with external data loggers (e.g., Omega OM-DAQPRO-5300) for spatial temperature validation per ASTM E2297-03.
Sample Compatibility & Compliance
The JH-ATL Series accommodates test specimens ranging from microelectromechanical systems (MEMS) sensors to full-scale avionics enclosures (up to 2 m³ internal volume, customizable). Chamber ports support feedthroughs for power, signal, and optical access—enabling in-situ monitoring of device-under-test (DUT) performance during thermal transients. All units comply with electromagnetic compatibility (EMC) requirements per EN 61326-1 and meet safety standards outlined in IEC 61010-1. For regulated aerospace applications, the chamber supports 21 CFR Part 11-compliant electronic signatures and audit trail generation when paired with validated software modules. Calibration certificates are traceable to NIM (National Institute of Metrology, China) and include as-found/as-left data per ISO/IEC 17025.
Software & Data Management
The embedded controller features a 10.1-inch capacitive touchscreen HMI with multilingual UI (English, Chinese, French, German). It supports CSV export of time-stamped temperature, humidity (if equipped), and alarm logs. Optional PC-based software (Jianhu TestSuite v4.2) provides GMP-aligned features including user role management (admin/operator/auditor), electronic batch records, deviation reporting, and automated report generation compliant with ISO 9001:2015 Annex A. Data encryption (AES-256) and secure FTP transfer ensure integrity during remote diagnostics and regulatory submission preparation.
Applications
- Thermal vacuum pre-screening of satellite payload electronics prior to TPS (Thermal Protection System) integration.
- Material coefficient-of-thermal-expansion (CTE) characterization of carbon-fiber-reinforced polymer (CFRP) airframe components.
- Qualification testing of inertial measurement units (IMUs), star trackers, and radiation-hardened FPGAs across mission-relevant thermal orbits.
- Environmental stress screening (ESS) of launch vehicle telemetry systems per NASA-HDBK-7120.5B.
- Accelerated life testing of thermal interface materials (TIMs) used in high-power RF amplifiers and phased-array antennas.
FAQ
Does the JH-ATL Series support custom chamber dimensions?
Yes—standard configurations range from 150 L to 1000 L internal volume; non-standard geometries (e.g., tall/slim, cylindrical, or split-chamber designs) are available upon engineering review.
Can the chamber be integrated into an existing test automation framework?
Yes—RS-485 Modbus RTU, Ethernet TCP/IP, and optional IEEE-488 (GPIB) interfaces enable seamless integration with LabVIEW, Python-based test sequencers, or enterprise MES platforms.
What calibration services are offered post-installation?
Jianhu provides on-site IQ/OQ/PQ validation packages aligned with ISO/IEC 17025, including uncertainty budgeting, sensor placement verification, and thermal gradient analysis reports.
Is remote firmware update capability supported?
Firmware updates are delivered via encrypted USB media or secure HTTPS portal; over-the-air (OTA) updates require prior security assessment and customer authorization per ITAR/EAR guidelines.
How does the system handle rapid thermal transitions without condensation or frost accumulation?
The chamber employs dew-point controlled defrost logic, dynamic airflow modulation, and optional nitrogen purge integration to suppress moisture ingress during sub-zero ramping phases.
