Jianhu JH-THP Series Programmable High-Low Temperature Environmental Test Chamber

Overview

The Jianhu JH-THP Series Programmable High-Low Temperature Environmental Test Chamber is an engineered solution for accelerated environmental stress screening (ESS), qualification testing, and long-term reliability validation in R&D labs and production QA/QC environments. Based on forced-air convection with dual-stage cascade refrigeration and PID-controlled resistive heating, the chamber delivers precise, repeatable thermal profiles across a wide operational range (–70 °C to +150 °C). Its architecture complies with the updated GB/T 10592–2025 national standard for environmental test chambers—mandating ≤±0.5 °C temperature fluctuation, ≥500-segment programmability, and audit-trail-capable data logging. Designed for high-integrity applications in electronics, new energy vehicles (NEV), aerospace components, and medical device manufacturing, the JH-THP integrates structural redundancy, explosion-proof variants (certified per IEC 60079-0 and ATEX Directive 2014/34/EU), and hardware-level synchronization for multi-chamber coordination.

Key Features

• Programmable thermal profiling with up to 500-step sequences, supporting ramp-hold-soak cycles, loop nesting, and real-time parameter override via front-panel HMI or Ethernet interface.
• Stable thermal performance: ±0.3 °C typical temperature fluctuation (verified per ISO 17025-accredited calibration report), ±2.0 °C uniformity across working volume (per IEC 60068-3-5).
• Dual-stage cascade refrigeration system using environmentally compliant R404A/R23 mixed refrigerant, enabling rapid cooling down to –70 °C without liquid nitrogen dependency.
• Explosion-proof configuration available with pressure-relief venting, intrinsically safe wiring, and certified enclosure (ATEX II 2G Ex db IIB T4 Gb / IECEx DBE 22.0022X).
• Modular chamber construction with stainless-steel interior (SUS304), double-wall insulation (polyurethane foam, 120 mm thickness), and electromagnetic-shielded observation window (optional).
• Embedded controller with non-volatile memory retention, USB data export, and optional cloud-sync capability for remote monitoring and firmware updates.

Sample Compatibility & Compliance

The JH-THP accommodates PCB assemblies, battery modules (Li-ion, solid-state), optical sensors, automotive ECUs, and polymer-based medical disposables. Its internal dimensions are fully customizable—from compact 100 L units for benchtop qualification to 300 L industrial-grade chambers with reinforced floor loading (up to 150 kg). All models meet mandatory requirements of GB/T 10592–2025 and support traceable compliance documentation including CNAS-accredited factory calibration certificates (traceable to NIM), full test reports per IEC 60068-2-1 (cold), IEC 60068-2-2 (dry heat), and IEC 60068-2-14 (change of temperature). Optional UL 61010-1 and UL 60950-1 certification packages are available for North American market deployment; CE marking (including Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU) and FDA 21 CFR Part 11–compliant software validation kits can be supplied upon request.

Software & Data Management

The chamber operates under Jianhu’s proprietary TH-Control v4.2 firmware, which supports GLP/GMP-aligned data integrity protocols: time-stamped event logs, user-access levels (admin/operator/guest), electronic signatures, and immutable audit trails retained for ≥5 years. Data export formats include CSV, PDF test reports, and XML (compatible with LabWare LIMS and Siemens Opcenter Quality). Optional integration with PLC systems (Modbus TCP/RTU, EtherNet/IP) enables synchronized operation with adjacent equipment such as vibration shakers or power cycling units. Remote access is secured via TLS 1.2–encrypted web interface; no third-party cloud hosting is used—data residency remains on-premise unless explicitly configured by the end user.

Applications

• Electronics reliability: Thermal cycling of semiconductor packages (JEDEC JESD22-A104), solder joint fatigue analysis, and burn-in screening of 5G RF modules.
• New energy vehicle validation: Battery module thermal runaway propagation testing (UN 38.3, GB/T 31467.3), motor inverter thermal shock endurance (–40 °C ↔ +125 °C, ΔT ≥15 °C/min).
• Aerospace component qualification: Environmental stress screening of avionics enclosures per MIL-STD-810H Method 501.7/502.7.
• Pharmaceutical stability: ICH Q1A(R2)-aligned long-term and accelerated stability studies (25 °C/60% RH, 40 °C/75% RH), with optional humidity control add-on.
• Materials science: Polymer crystallinity assessment via controlled cooling ramps, elastomer compression set evaluation at elevated temperatures.

FAQ

Does the JH-THP series comply with GB/T 10592–2025 out of the box?
Yes. All units shipped after January 2025 include firmware v4.2 and mechanical configurations pre-validated against the updated standard—including mandatory 500-segment program storage, ±0.5 °C fluctuation tolerance, and calibrated sensor placement per Clause 6.3.
Can the chamber be integrated into an existing MES or SCADA infrastructure?
Yes. Standard Modbus TCP and optional EtherNet/IP drivers are provided. Integration documentation includes register maps, sample Python scripts, and commissioning checklists aligned with ISA-95 Level 0–2 data exchange requirements.
What level of after-sales support is available in Shenzhen?
Jianhu maintains a dedicated logistics hub in Bao’an District with local spare parts inventory. On-site calibration and technical intervention are guaranteed within 90 minutes for metrological services and 4 hours for critical hardware faults—subject to SLA agreement.
Is remote firmware update supported, and is it validated per IEC 62304?
Yes. Firmware updates are digitally signed and delivered via secure HTTPS. Update validation reports—including unit testing, regression testing, and risk analysis per IEC 62304 Class B—are available under NDA upon request.
Are CNAS calibration certificates included with delivery?
Yes. Each unit ships with a CNAS-accredited calibration certificate (No. CNAS LXXXXX) covering temperature uniformity, fluctuation, and deviation at three load points (center, upper corner, lower corner), valid for 12 months from date of shipment.
