Overview
The LabCompanion HH-3 High-Temperature Aging Test Chamber is an industrial-grade environmental test system engineered for precise, stable, and repeatable thermal aging evaluation of materials, components, and finished products under elevated temperature conditions. Designed in accordance with fundamental principles of convective heat transfer and thermal equilibrium control, the chamber employs a dual-channel horizontal air circulation architecture to ensure uniform thermal distribution across its 225 L working volume (750 × 600 × 500 mm). Its operational range spans from ambient +10 °C up to 250 °C — a capability critical for accelerated life testing, polymer degradation studies, coating curing validation, and electronic component reliability screening. The unit integrates a bottom-mounted stainless steel tubular heating system, 80 mm thick glass wool insulation, and a 40 W high-efficiency centrifugal blower — collectively enabling rapid thermal ramping, minimal overshoot, and long-term stability at maximum setpoints.
Key Features
- Dual-channel horizontal forced-air circulation ensures consistent airflow velocity and minimizes thermal stratification — validated by ISO 17025-aligned internal mapping protocols
- Stainless steel interior chamber and ductwork resist oxidation and corrosion at sustained temperatures up to 250 °C, supporting GLP-compliant cleaning and residue-free operation
- Digital PID temperature controller with Pt100 RTD feedback delivers resolution of 0.1 °C and repeatability within ±0.3 °C over 24-hour continuous operation
- Programmable timer (0.01–99.99 h) with automatic power cutoff and audible alarm enhances process safety and unattended operation integrity
- Comprehensive electrical protection suite includes short-circuit interruption, motor thermal overload detection, and three-phase loss monitoring (for optional 380 V configurations)
- Cold-rolled steel outer casing with epoxy-polyester powder coating (light gray RAL 7035) provides mechanical durability and chemical resistance in shared laboratory or production-floor environments
Sample Compatibility & Compliance
The HH-3 accommodates a broad spectrum of sample types — including metallic alloys, thermosetting resins, elastomers, printed circuit boards (PCBs), pharmaceutical excipients, and composite laminates — without risk of cross-contamination or catalytic surface interaction. Its stainless steel construction and absence of organic gaskets or adhesives near the hot zone comply with ASTM D3045 (Standard Practice for Heat Aging of Plastics), IEC 60068-2-2 (Environmental Testing – Part 2-2: Tests – Test B: Dry Heat), and MIL-STD-810G Method 501.5. While not certified for Class I Div 2 hazardous locations, the chamber meets CE marking requirements per EN 61000-6-3 (EMC Emission) and EN 61000-6-2 (Immunity), and conforms to RoHS Directive 2011/65/EU for restricted substances.
Software & Data Management
The HH-3 operates as a standalone instrument with embedded firmware; no proprietary software is required for basic functionality. However, optional RS485 Modbus RTU interface enables integration into centralized SCADA or MES platforms for real-time temperature logging, alarm event capture, and audit trail generation. When connected to compliant data acquisition systems, the chamber supports 21 CFR Part 11–aligned electronic records — including user authentication, timestamped parameter changes, and immutable session logs — facilitating FDA-regulated stability studies and quality assurance workflows under GMP Annex 11.
Applications
- Accelerated aging of automotive seals, gaskets, and under-hood plastics per SAE J2236
- Thermal endurance qualification of insulating materials used in transformers and motors (IEC 60216)
- Pre-conditioning of lithium-ion battery cells prior to electrochemical cycling tests
- Moisture removal and residual solvent evaporation in active pharmaceutical ingredient (API) processing
- Validation of paint and powder coating cure profiles in aerospace OEM supply chains
- Long-term thermal stress screening of optical adhesives and encapsulants in photonics packaging
FAQ
What is the maximum continuous operating temperature of the HH-3?
The chamber is rated for continuous operation at 250 °C, with thermal stability maintained within ±1.6% of setpoint across the full working volume.
Can the HH-3 be used for humidity-controlled aging tests?
No — the HH-3 is a dry-heat-only chamber. For combined temperature/humidity stress testing, consider the LabCompanion TH-3 Series Thermal-Humidity Chambers.
Is calibration documentation included with shipment?
A factory-as-tested calibration certificate (traceable to NIM, China) is provided. Optional UKAS-accredited calibration services are available upon request.
Are custom shelf configurations or port fittings available?
Yes — LabCompanion offers OEM engineering support for modified interior layouts, cable feedthroughs, and DIN-rail mounting brackets, subject to structural integrity review.
Does the unit meet international shipping standards for export?
All HH-3 units are packed in ISPM-15 compliant wooden crates with desiccant and vibration-dampening foam, meeting IATA and IMDG requirements for global air and sea freight.
