Jianhu JH-RTP Series Rapid Temperature Change Chamber

Overview

The Jianhu JH-RTP Series Rapid Temperature Change Chamber is an engineered environmental simulation system designed for accelerated reliability assessment under dynamic thermal stress conditions. It operates on the principle of forced-air convection combined with a dual-stage cascade refrigeration cycle and high-efficiency resistive heating elements, enabling precise, repeatable transitions between extreme temperature extremes. Unlike static thermal chambers, the JH-RTP series delivers controlled ramp rates up to 15 °C/min (typical, dependent on load and setpoint span), making it suitable for compliance testing against IEC 60068-2-14 (change of temperature), IEC 60068-2-38 (combined temperature/humidity cycling), and GB/T 2423.34—standards widely adopted in electronics qualification, automotive component validation, and aerospace hardware screening. Its architecture supports both single-step and multi-segment thermal profiles, facilitating test protocols such as HALT (Highly Accelerated Life Testing), ELT (Environmental Stress Screening), and qualification per MIL-STD-810G Method 503.4.

Key Features

• Temperature range spanning −70 °C to +150 °C, validated across full operational envelope using NIST-traceable PT100 sensors
• Dual-stage cascade compressor system with environmentally compliant R404A/R23 refrigerant blend, optimized for rapid cooldown without oil carryover or frost accumulation
• Explosion-proof configuration available (ATEX II 2G Ex db IIB T4 Gb / IECEx DBE22.0001X), meeting requirements for battery cell testing, solvent-based material evaluation, and hazardous area deployment
• Stainless steel 304 interior chamber and insulated double-wall construction ensure long-term corrosion resistance and thermal integrity
• Microprocessor-based controller with 7-inch color touchscreen interface, supporting profile programming, real-time trend display, alarm logging, and USB data export
• Onboard data logger stores ≥200,000 timestamped records (temperature, time, alarm status), compliant with GLP/GMP audit trail requirements
• Optional Ethernet/RS485 communication ports enable integration with MES, LIMS, or SCADA systems via Modbus TCP or ASCII protocol

Sample Compatibility & Compliance

The JH-RTP chamber accommodates diverse sample geometries—from PCB assemblies and semiconductor packages to EV battery modules and medical device enclosures—via customizable interior dimensions (100 L to 1000 L standard; non-standard builds supported). All units undergo factory calibration per ISO/IEC 17025-accredited procedures and are supplied with a Certificate of Conformance detailing traceability to national standards. The system meets electromagnetic compatibility (EMC) requirements per EN 61326-1 and safety standards per IEC 61010-1. For regulated industries, optional features include 21 CFR Part 11-compliant electronic signatures, user access level management (admin/operator/guest), and encrypted audit logs. Validation documentation (IQ/OQ/PQ templates) is provided upon request to support FDA, ISO 13485, or IATF 16949 implementation.

Software & Data Management

Jianhu’s proprietary ChamberControl™ software (Windows-compatible, license-free) enables remote monitoring, automated report generation (PDF/CSV), and synchronized multi-chamber coordination. Data integrity safeguards include cyclic redundancy check (CRC) validation for all stored records, write-protection for historical datasets, and automatic backup to network drives or cloud storage (AWS S3 or Azure Blob). The system supports configurable alarm thresholds (deviation, rate-of-change, duration), email/SMS notification via SMTP gateway, and integration-ready APIs for custom dashboard development. All firmware updates are digitally signed and delivered through secure HTTPS channels to prevent unauthorized modification.
