High-Temperature & High-Pressure Aging Chamber

Overview

The High-Temperature & High-Pressure Aging Chamber is an engineered environmental test system designed for accelerated thermal aging evaluation of materials, components, and finished products under controlled elevated temperature and optional pressure conditions. While this base model operates as a high-temperature convection oven, its structural integrity, sealed chamber design, and configurable pressure interface support integration with external pressurization modules—enabling compliance with combined thermal-pressure stress testing protocols per GB/T 2423.2, IEC 60068-2-2, and ASTM D3045. The chamber utilizes forced-air circulation via bottom-mounted axial fans and dual independently controlled far-infrared heating elements to ensure rapid thermal ramping and stable equilibrium across the working volume. Its microprocessor-based control architecture continuously monitors and adjusts power output using real-time feedback from calibrated PT100 sensors, delivering reproducible thermal profiles essential for reliability qualification in electronics, polymers, automotive seals, and aerospace composites.

Key Features

• Robust dual-zone heating system: Two 2 kW nickel-chromium far-infrared heaters operate independently, allowing segmented thermal profiling and redundancy for continuous operation.
• Precision temperature regulation: ±0.5°C control accuracy and ±1.5°C uniformity across the full internal volume (450 × 400 × 400 mm), validated per ISO/IEC 17025 traceable procedures.
• Corrosion-resistant construction: Interior chamber fabricated from SUS#304 stainless steel; exterior housing features electrostatically applied powder coating over cold-rolled steel for long-term durability.
• Intelligent microprocessor controller: Touch-enabled digital interface with programmable ramp-soak cycles, user-defined timer (0–999 minutes), data logging capability, and password-protected parameter locking.
• Safety-critical protection suite: Integrated overtemperature cutoff, earth leakage circuit breaker (ELCB), audible/visual alarm triggers, and automatic heater shutdown upon sensor failure.
• Modular scalability: Chamber body and door sealing are rated for optional pressurization up to 0.5 MPa (5 bar) when interfaced with certified external gas supply and pressure monitoring systems.

Sample Compatibility & Compliance

This chamber accommodates non-volatile, non-explosive, and non-dripping samples—including PCB assemblies, elastomeric gaskets, insulating resins, ceramic substrates, and coated metal parts. It excludes flammable solvents, volatile organic compounds (VOCs), and liquids prone to vaporization or condensation within the operating range. Designed and verified to meet the thermal test requirements of GB/T 2423.2 (equivalent to IEC 60068-2-2 Test Bb), it supports qualification testing for MIL-STD-810, JEDEC JESD22-A108, and IPC-9701. Optional calibration certificates (NIST-traceable) and IQ/OQ documentation packages are available to support GLP, GMP, and FDA 21 CFR Part 11-compliant validation workflows.

Software & Data Management

The embedded controller supports RS485 communication (Modbus RTU protocol) for integration into centralized laboratory information management systems (LIMS) or SCADA platforms. Real-time temperature data can be streamed to external PCs for automated reporting, trend analysis, and audit trail generation. Optional software add-ons provide CSV export, graphical profile visualization, deviation alerting, and electronic signature-enabled report generation—fully aligned with 21 CFR Part 11 requirements for electronic records and signatures in regulated environments.

Applications

• Accelerated life testing of polymer encapsulants, adhesives, and conformal coatings under sustained thermal stress.
• Pre-conditioning of electronic components prior to HALT/HASS screening or solderability verification.
• Thermal stability assessment of battery separator membranes and cathode active materials.
• Outgassing behavior analysis of space-grade materials per ECSS-Q-ST-70-02C.
• Process validation of heat-curing cycles in composite layup and adhesive bonding operations.
• Compliance verification for automotive component standards including ISO 16750-4 and AEC-Q200 stress tests.

FAQ

Does this chamber support true high-pressure operation out-of-the-box?

No. This standard configuration is a high-temperature aging chamber. High-pressure functionality requires integration with an externally supplied, CE-certified pressure vessel module and associated safety interlocks—available as a customized engineering package.

Can the temperature range be extended beyond 300°C?

Yes. Custom variants are offered with upgraded insulation, high-temp door gaskets, and 500°C-rated heaters—subject to structural reinforcement and additional safety certification.

Is third-party calibration included with delivery?

A factory calibration report is provided. NIST-traceable on-site calibration and annual recalibration services are available upon request.

What is the maximum load capacity per shelf?

Each SUS#304 wire shelf supports up to 15 kg uniformly distributed load. Load distribution must avoid blocking airflow grilles located at the chamber base and left-side duct outlet.

How is thermal uniformity verified during installation qualification?

IQ includes 9-point temperature mapping per ASTM E2297-03 using calibrated thermocouples, with results documented in a formal validation report compliant with ISO/IEC 17025.
