Xuzhou Rapid Temperature Change Chamber Manufacturer

Overview

The Xuzhou Rapid Temperature Change Chamber is an environmental test system engineered for accelerated thermal stress screening of electronic components, automotive modules, aerospace assemblies, and industrial materials. It operates on the principle of controlled, high-rate thermal cycling—inducing repeated expansion and contraction in test specimens by rapidly alternating between extreme temperature limits (–70 °C to +150 °C). This accelerates the manifestation of latent defects—including material microcracks, interfacial delamination, solder joint fatigue, and process-induced voids—before field deployment. Unlike standard thermal shock or steady-state chambers, this system delivers programmable ramp rates up to 25 °C/min across defined temperature bands (e.g., –45 °C ↔ +85 °C), enabling precise replication of real-world thermal transients encountered during operational startup, altitude changes, or diurnal cycling.

Key Features

• Programmable rapid temperature transition: selectable ramp rates of 5, 10, 15, 20, and 25 °C/min within user-defined temperature boundaries
• Integrated humidity control: wide operating range of 20–98% RH (optional extended range: 5–98% RH)
• High-precision conditioning: temperature uniformity ±2 °C, humidity uniformity ±3.0% RH (at ≥75% RH), temperature fluctuation ±0.5 °C, humidity fluctuation ±2.5% RH
• Robust chamber construction: interior and exterior walls fabricated from SUS#304 stainless steel for corrosion resistance and long-term stability
• Energy-efficient refrigeration: fully sealed, low-noise dual-stage compressor system utilizing environmentally compliant refrigerants R404A and R23
• Intuitive human-machine interface: 7-inch color LCD touchscreen controller with bilingual (English/Chinese) display and real-time graphical trend logging
• Flexible power configuration: tri-phase 5-wire AC380 V ±5%, 50 Hz ±0.5 Hz; rear-mounted power inlet with 2.5 m cable

Sample Compatibility & Compliance

This chamber accommodates a broad spectrum of sample geometries via customizable internal dimensions—from KS-TH-225 (50 × 75 × 60 cm) to KS-TH-1000 (100 × 100 × 100 cm)—allowing integration of full subassemblies, PCB stacks, or molded enclosures. The system complies with multiple international and national environmental testing standards, including ISO/IEC 17025-aligned validation protocols. It supports execution of ASTM D5276 (thermal cycling for packaging), IEC 60068-2-14 (Test N: Change of Temperature), and MIL-STD-810H Method 503.7 (Temperature Shock). Domestic compliance includes GB/T 2423.1–2023 (Cold Test), GB/T 2423.2–2023 (Dry Heat), GB/T 2423.22–2012 (Temperature Change), GJB 150.3A–2009 (High Temperature), GJB 150.4A–2009 (Low Temperature), and GB/T 10589–2015 (Low-Temperature Chamber Requirements).

Software & Data Management

The embedded controller enables full cycle definition—including dwell times, ramp profiles, humidity setpoints, and step sequencing—with non-volatile memory retention. All operational parameters and real-time sensor data (temperature, humidity, ramp rate, alarm status) are timestamped and exportable via USB to CSV format. While the base system does not include network connectivity or remote supervision, it supports GLP/GMP-aligned audit trails when paired with external data acquisition systems meeting FDA 21 CFR Part 11 requirements for electronic records and signatures. Calibration verification points are traceable to national metrology institutes per ISO/IEC 17025 guidelines.

Applications

• Qualification testing of avionics and satellite subsystems under thermal cycling stress
• Reliability assessment of lithium-ion battery packs during charge/discharge thermal transients
• Process validation for conformal coating adhesion and encapsulant integrity
• Design verification of MEMS sensors subjected to ambient thermal gradients
• Failure analysis root cause identification in field-return electronics
• Pre-compliance screening prior to formal certification per AEC-Q200 or JEDEC JESD22-A104

FAQ

What is the maximum achievable ramp rate, and is it sustained across the full temperature range?
The system achieves up to 25 °C/min within user-specified temperature bands (e.g., –45 °C to +85 °C); sustained ramp performance is verified at nominal load conditions per GB/T 2423.22–2012 Annex B.
Does the chamber support automated test sequencing with conditional logic (e.g., “if temperature deviation > ±1.0 °C, pause and alert”)?
The standard controller supports fixed-sequence programming but lacks embedded conditional branching; such functionality requires integration with external PLC or SCADA platforms.
Is third-party calibration documentation included with shipment?
Factory calibration certificates (traceable to CNAS-accredited labs) are provided; on-site IQ/OQ protocol execution and annual recalibration services are available under separate service agreement.
Can the humidity system operate independently of temperature cycling?
Yes—standalone constant-humidity mode is supported at any stable temperature setpoint within the chamber’s operating envelope.
What safety interlocks are implemented to protect samples and operators?
Dual redundant over-temperature cutoffs, door-open safety shutdown, refrigerant pressure monitoring, and real-time heater current sensing are integrated into the control architecture per IEC 61000-6-2 EMC and IEC 61010-1 safety standards.
