Overview
The Generic High-Low Temperature Cycling Test Chamber is an engineered environmental simulation system designed to subject electronic components, automotive parts, aerospace materials, and industrial assemblies to controlled, programmable thermal stress profiles. Operating on the principle of forced-air convection with dual-stage refrigeration and electric heating, the chamber delivers precise temperature transitions between −70 °C and +180 °C (typical standard range; exact limits depend on configuration), with ramp rates adjustable from 1 °C/min to 10 °C/min. Its sealed, insulated enclosure minimizes thermal leakage and ensures high spatial uniformity (±1.0 °C at setpoint, per IEC 60068-3-5) and stability (±0.5 °C over 2 hours). The chamber supports both static temperature soak and dynamic cycling protocols—critical for accelerated life testing, qualification validation, and failure mode analysis in R&D and production QA environments.
Key Features
- Robust stainless-steel inner chamber with seamless welding and anti-corrosion finish for long-term exposure to thermal shock and humidity-free operation
- High-efficiency hermetic compressor system with eco-friendly R404A/R23 cascade refrigeration, enabling rapid cooldown without oil carryover or frost accumulation
- Intelligent PID + fuzzy logic temperature controller with real-time deviation compensation and auto-tuning capability
- Integrated load power feedthrough (up to 20 A, 250 V AC) supporting powered-in-use testing (e.g., functional verification of PCBs under thermal stress)
- Double-layer tempered glass observation window with Philips LED lighting and built-in resistive heating film to prevent condensation and maintain optical clarity during low-temperature operation
- Comprehensive safety architecture: over-temperature cut-off, compressor high-pressure protection, phase-sequence monitoring, door interlock switch, and ground-fault circuit interrupter (GFCI)
Sample Compatibility & Compliance
The chamber accommodates test specimens up to 600 mm × 600 mm × 600 mm (W×D×H) with internal volume options ranging from 100 L to 1000 L. It is compatible with non-volatile, non-explosive, and non-outgassing samples—including printed circuit boards, sensors, battery modules, polymer housings, and coated metal substrates. All performance verifications align with internationally recognized metrological standards: GB/T 5170.2–2017 (Temperature Testing Equipment), IEC 60068-3-5 (Thermal Shock and Cycling Guidance), MIL-STD-810H Method 501.7 (High Temperature) and 502.7 (Low Temperature), and ISO 16750-4 (Road Vehicles – Environmental Conditions). Calibration traceability is supported via NIST-traceable reference probes (optional accessory).
Software & Data Management
Equipped with a 7-inch color TFT touchscreen HMI, the chamber enables intuitive profile programming—including multi-step ramps, dwells, loops, and conditional branching. Optional PC-based software (Windows-compatible, USB/Ethernet interface) provides full data logging at user-defined intervals (minimum 1 s), real-time graphing, CSV export, and audit trail generation compliant with FDA 21 CFR Part 11 requirements (when configured with user authentication and electronic signature modules). Data integrity safeguards include cyclic redundancy check (CRC) file verification and automatic backup to external USB storage.
Applications
This test chamber serves critical roles across multiple regulated and industrial sectors: qualification testing of avionics per DO-160 Section 4; thermal cycling validation of Li-ion battery cells per UL 1642 and UN 38.3; solder joint reliability assessment using JEDEC JESD22-A104; aging studies of elastomeric seals under ASTM D573; and pre-compliance screening for automotive ECUs per ISO 16750-4. It is routinely deployed in GLP-compliant laboratories, Tier-1 supplier QC labs, and university materials science departments conducting thermomechanical fatigue research.
FAQ
Is this chamber suitable for humidity-controlled testing?
No—this is a dry-thermal cycling chamber. Humidity functionality requires a separate combined temperature/humidity test chamber (e.g., model series THx).
Can the chamber be integrated into a factory MES or SCADA system?
Yes—Modbus RTU/TCP and optional Ethernet/IP protocols are available for seamless PLC-level integration and centralized monitoring.
What documentation is provided for IQ/OQ validation?
A complete validation support package—including URS template, FAT/SAT checklists, calibration certificates, and protocol-ready test records—is supplied upon request.
Does the quoted price include installation, commissioning, or training?
No—the indicated price reflects ex-works cost only. On-site installation, operational qualification, and operator training are available as billable services.
Are spare parts and extended warranties available?
Yes—standard 12-month warranty is included; extended coverage (up to 36 months) and genuine OEM spare parts (compressor kits, controllers, sensors) are offered through authorized distribution channels.
