High Low Temperature Test Chamber – General OEM Model

Overview

The High Low Temperature Test Chamber – General OEM Model is a precision-engineered environmental simulation system designed for controlled thermal stress testing of electronic components, automotive parts, aerospace materials, and industrial assemblies. Operating on the principle of forced-air convection with dual-stage refrigeration and PID-controlled electric heating, this chamber delivers stable, repeatable temperature profiles across a wide operational range—typically –40 °C to +150 °C (configurable per model variant). Its architecture complies with fundamental thermal test chamber design principles defined in IEC 60068-3-5 and ISO 16750-4 for environmental robustness validation. The unit is intended for laboratory-based qualification testing, reliability screening (e.g., HALT pre-screening), and routine compliance verification under standardized thermal cycling conditions.

Key Features

• Rounded ergonomic enclosure with matte-finish stainless steel exterior and seamless welded interior chamber—minimizing thermal bridging and enhancing long-term corrosion resistance;
• Non-rebound planar door handle mechanism with magnetic gasket seal, ensuring consistent compression force and leak-tight integrity during operation;
• Hermetically sealed refrigeration circuit utilizing environmentally compliant R404A or R507 refrigerant (subject to regional regulations), coupled with low-noise scroll compressors and high-efficiency finned evaporators;
• Integrated anti-vibration mounting pads (EPDM rubber compound, Shore A 60 hardness) reducing structure-borne transmission to ≤45 dB(A) at 1 m distance under full-load cycling;
• Electrical feedthrough capability (up to 30 A / 250 V AC) with IP65-rated connectors—enabling real-time powered-device-in-test (DUT) monitoring during thermal exposure;
• Philips LED observation window lighting (6500 K CCT, 120° beam angle) combined with resistive glass-heating demisting system (12 V DC, 25 W/m²) for uninterrupted visual inspection without condensation interference;
• Multi-layer safety architecture including over-temperature cut-off (mechanical backup), compressor high-pressure switch, phase failure protection, and door-open interlock with automatic power cutoff.

Sample Compatibility & Compliance

This test chamber accommodates standard sample racks (max. 500 mm × 500 mm × 500 mm internal volume; optional larger configurations available). It supports specimens with active power draw, embedded sensors, or data cables routed via dedicated feedthrough ports. The system meets the metrological and performance validation criteria outlined in GB/T 5170.2–2017 (equivalent to IEC 60068-3-5 Ed. 3.0), GB/T 10592–2008, and MIL-STD-810G Method 501.6/502.6. Calibration traceability follows ISO/IEC 17025 requirements when performed by an accredited service provider. While not pre-certified to UL or CE as a standalone product (as supplied via distributor channel), it is fully compatible with third-party conformity assessment pathways for end-user integration into ISO 9001, IATF 16949, or AS9100-compliant quality systems.

Software & Data Management

The chamber integrates with optional PC-based control software supporting RS485 (Modbus RTU) or Ethernet (TCP/IP) communication protocols. Logged data—including chamber setpoint, actual chamber temperature, DUT thermocouple inputs (Type K/J), cycle count, and alarm history—is timestamped and stored in CSV format compliant with 21 CFR Part 11 audit trail requirements when configured with user authentication and electronic signature modules. Data export supports automated FTP upload or local SD card archiving. All firmware updates are delivered via signed binary packages with SHA-256 hash verification to ensure integrity.

Applications

• Temperature cycling validation per JEDEC JESD22-A104 for semiconductor packaging;
• Thermal shock pre-screening of PCBAs prior to burn-in;
• Material coefficient-of-thermal-expansion (CTE) characterization under controlled ramp rates (1–5 °C/min typical);
• Automotive component endurance testing per ISO 16750-4 and GMW3172;
• Accelerated aging studies for polymer seals, adhesives, and encapsulants;
• Verification of thermal management system performance in battery modules and power electronics enclosures.

FAQ

Does this chamber support programmable ramp-soak-cycle profiles?
Yes—up to 99 segments per program, with adjustable ramp rates, dwell times, and loop counts. Profiles are retained in non-volatile memory after power loss.
Is NIST-traceable calibration documentation included?
Calibration certificates are provided upon request and performed by ISO/IEC 17025-accredited laboratories. Standard delivery includes factory verification report only.
Can the chamber be integrated into a central lab monitoring network?
Yes—via Modbus TCP or optional OPC UA server add-on, enabling interoperability with SCADA, MES, or LIMS platforms.
What is the standard warranty coverage?
24 months parts-and-labor limited warranty from date of commissioning, excluding consumables and damage from improper installation or misuse.
Are custom chamber dimensions or temperature ranges available?
Yes—OEM engineering collaboration is supported for bespoke configurations, including extended low-temperature options (–70 °C), humidity integration (combined temp/humidity chambers), or explosion-proof variants (ATEX/IECEx certified).
