YUELIAN PW-CFT150-40L10 Rapid Temperature Change Test Chamber

Overview

The YUELIAN PW-CFT150-40L10 Rapid Temperature Change Test Chamber is an engineered environmental simulation system designed for accelerated thermal stress testing of electronic components, automotive modules, aerospace hardware, and polymer-based materials. It operates on a dual-refrigerant cascade refrigeration cycle (R404A/R23), enabling precise and repeatable transitions across extreme temperature boundaries—from cryogenic -40 °C to high-temperature +150 °C—while maintaining strict humidity control (20–98 % RH). Its architecture complies with the thermal performance requirements outlined in IEC 60068-2-14 (Test N: Change of Temperature) and supports test profiles referenced in MIL-STD-810H Method 503.7 and JEDEC JESD22-A104F. The chamber integrates a water-cooled condenser system for stable operation under continuous thermal cycling, eliminating ambient dependency common in air-cooled alternatives.

Key Features

• High-fidelity 7-inch color touchscreen controller with embedded PID auto-tuning, 12 programmable test sequences (up to 120 segments per program), and full data logging capability.
• Temperature resolution of ±0.01 °C and humidity resolution of ±0.01 % RH, with real-time graphical display of active profile curves and cumulative runtime tracking.
• Dual-stage refrigeration system using environmentally compliant R404A (high-stage) and R23 (low-stage) refrigerants, paired with imported ALCO dry filters, RAINBOW high-pressure safety switches, and SANYO/Embraco hermetic compressors.
• Uniform airflow distribution via twin 60 W long-shaft motors driving multi-wing impellers and adjustable louvered ducting—ensuring ≤2.0 °C internal temperature uniformity per IEC 60068-3-5.
• Robust thermal insulation comprising rigid polyurethane foam (≥100 mm thickness) and layered glass wool, minimizing thermal leakage and energy consumption during extended cycling protocols.
• Triple-layer vacuum-view window (tempered glass), stainless-steel (SUS#304) interior chamber, electrostatically coated steel exterior, and reinforced angle-iron base frame for structural integrity and vibration damping.

Sample Compatibility & Compliance

The PW-CFT150-40L10 accommodates standard industrial samples up to 5 kg mass (e.g., PCB assemblies, sensors, battery cells, molded plastics) within its 150 L working volume. Its design conforms to key regulatory and industry frameworks including ISO/IEC 17025 calibration traceability pathways, ASTM E145-22 (Standard Specification for Gravity-Convection and Forced-Ventilation Ovens), and GLP-compliant test documentation requirements. Optional validation packages support IQ/OQ/PQ execution per FDA 21 CFR Part 11 guidelines when integrated with compliant data acquisition software. Safety systems include dual-stage compressor overheat protection, high-pressure cutouts, solid-state relay monitoring, dry-burn prevention for humidification elements, and fail-safe door interlocks.

Software & Data Management

The built-in controller provides native RS485/RS232 communication interfaces and optional Ethernet connectivity for remote monitoring and centralized fleet management. A Windows-based PC software suite (included) enables bidirectional parameter upload/download, real-time telemetry streaming, alarm event timestamping, and PDF report generation with digital signature support. Audit trails record all user actions—including setpoint modifications, program starts/stops, and fault acknowledgments—with immutable timestamps. Data export formats include CSV and XML, facilitating integration into LIMS platforms or enterprise MES systems. Firmware updates are delivered via USB flash drive with version-controlled checksum verification.

Applications

This chamber serves critical roles in reliability engineering workflows: thermal shock qualification per IPC-9701A, solder joint fatigue analysis under cyclic thermal loading, moisture resistance validation of conformal coatings (per IPC-CC-830B), and preconditioning prior to HALT/HASS testing. It is routinely deployed in Tier-1 automotive supplier labs for ISO/TS 16949-compliant PPAP submissions, in semiconductor packaging facilities for JEDEC-standard pre-conditioning, and in academic materials science laboratories investigating phase transition kinetics in shape-memory alloys and thermoplastic elastomers.

FAQ

What is the minimum dwell time between temperature extremes in a single cycle?

The controller supports programmable dwell periods from 0 minutes to 99 hours 59 minutes per segment; typical thermal shock protocols specify 10–30 minute dwells at each extreme to ensure thermal equilibrium.

Can the chamber operate unattended for extended durations?

Yes—equipped with non-volatile memory, power-loss recovery, and comprehensive hardware-level safety interlocks, it supports fully autonomous execution of multi-day test programs.

Is humidity control available during sub-zero temperature phases?

Humidity modulation is disabled below +5 °C to prevent condensation and ice formation on sensor elements and chamber walls; RH control resumes automatically above this threshold.

What calibration standards does the controller support?

The controller accepts external PT100 reference inputs for field verification and supports NIST-traceable calibration certificates for temperature and humidity sensors upon request.

Are custom test ports or mounting fixtures available?

Standard configuration includes one 100 mm diameter access port on the left side wall with stainless-steel flange and silicone gasket; OEM-specific penetrations or rack-mount brackets can be supplied under engineering consultation.
