High Temperature Constant Temperature Chamber

Overview

The High Temperature Constant Temperature Chamber is a precision-engineered environmental test chamber designed for thermal stability evaluation, accelerated aging, and high-temperature performance validation of materials and components across aerospace, automotive, electronics, and industrial R&D sectors. Operating on the principle of forced convection heating with PID-controlled thermal regulation, it maintains stable, uniform temperature fields within a wide operational range—from ambient +20°C up to 500°C—enabling standardized thermal stress testing in accordance with international reliability protocols. Its robust architecture integrates independent high-temperature heating circuits, eliminating thermal cross-talk during prolonged exposure tests, while the dual-layer insulation system (polyurethane foam core + glass fiber cladding) ensures minimal heat loss and superior energy efficiency under continuous high-load operation.

Key Features

• Stable thermal environment: Achieves ±1.0°C temperature uniformity (measured at 9-point grid per IEC 60068-3-5) across the working volume at 300°C, validated via traceable Pt100 sensor array calibration.
• Industrial-grade construction: Exterior formed from CNC-machined 1.2 mm SECC steel with electrostatic powder coating; interior chamber fabricated from seamless SUS304 stainless steel to resist oxidation and thermal fatigue up to 500°C.
• Precision control system: Fuji Electric PXR series PID controller with SSR solid-state relay output delivers microsecond-level power modulation, enabling rapid ramp rates (up to 5°C/min) and sub-degree steady-state stability.
• Forced horizontal airflow: High-efficiency, high-temperature-rated turbine fan ensures laminar, low-turbulence circulation—critical for minimizing thermal gradients during long-duration aging tests.
• Dual-safety architecture: Independent overtemperature protection circuit (mechanical backup switch) operates in parallel with electronic limit monitoring; leakage current detection complies with IEC 61000-4-5 surge immunity requirements.

Sample Compatibility & Compliance

The chamber accommodates diverse sample geometries—including PCB assemblies, polymer composites, battery cells, and metallic fasteners—within customizable internal dimensions (standard models: W600 × D500 × H600 mm; custom configurations available upon engineering review). All structural and control subsystems conform to essential safety and electromagnetic compatibility directives: IEC 61000-6-2 (immunity), IEC 61000-6-4 (emission), and UL 61010-1 (electrical safety). Test methodologies executed in this chamber align with ASTM D3045 (thermal aging of plastics), ISO 188 (vulcanized rubber), and MIL-STD-810H Method 501.7 (high-temperature exposure), supporting GLP-compliant data generation when paired with validated calibration records and audit-trail-enabled software.

Software & Data Management

While the base configuration utilizes standalone Fuji controller with local display and manual setpoint adjustment, optional Ethernet-enabled data logging modules support real-time acquisition of temperature profiles (sampling interval: 1–60 sec), event-triggered alarms, and CSV export for post-test analysis. When integrated with third-party LIMS or MES platforms, the chamber supports Modbus TCP communication for centralized monitoring, remote parameter adjustment, and automated report generation—including time-stamped pass/fail status against user-defined thermal soak criteria. All digital records maintain full traceability per FDA 21 CFR Part 11 requirements when deployed with electronic signature and audit trail functionality.

Applications

• Accelerated thermal aging of elastomers, adhesives, and thermoset resins per ASTM D573 and ISO 11358.
• Pre-conditioning of lithium-ion battery modules prior to cycle life testing (UN 38.3 Section 38.3.4.1).
• Thermal stress screening of automotive ECUs and infotainment systems under ISO 16750-4.
• Outgassing characterization of space-grade materials per ECSS-Q-ST-70-02C.
• Validation of solder joint reliability in high-reliability PCB assemblies (IPC-J-STD-001, J-STD-020).

FAQ

What is the maximum continuous operating temperature?
The chamber is rated for continuous operation at 500°C, with thermal derating not required below this threshold. Structural integrity and sensor accuracy are verified per IEC 60068-2-2 Annex B.
Is the chamber suitable for use with flammable atmospheres?
No—this model is configured for air atmosphere only. Explosion-proof variants require ATEX/IECEx-certified modifications and must be specified at order stage.
Can the internal volume be customized for oversized samples?
Yes. Engineering consultation is provided for non-standard dimensions; lead time and structural reinforcement requirements are assessed case-by-case.
How often does the Pt100 sensor require recalibration?
Annual calibration is recommended per ISO/IEC 17025; factory calibration certificate with NIST-traceable reference is supplied with each unit.
Does the system include validation documentation for GxP environments?
IQ/OQ documentation templates are available upon request; full qualification support (including protocol development and execution) is offered as a professional services option.
