Suying GWS-Series High-Temperature High-Humidity Environmental Test Chamber (Dual 85 Chamber)

Overview

The Suying GWS-Series High-Temperature High-Humidity Environmental Test Chamber is an engineered solution for accelerated environmental stress testing under controlled dual 85 conditions (85°C / 85% RH). Designed in accordance with rigorous international and automotive industry standards—including ISO 6270-2, DIN 50018, IEC 60068-3-5, and GMW 14729-B—the chamber delivers precise, repeatable thermal and hygrothermal exposure for reliability validation of electronic components, photovoltaic modules, automotive parts, and packaging materials. Its operational envelope spans +50°C to +95°C and 80–98% RH, enabling compliance with critical test protocols such as IEC 61730-2 (PV module safety qualification), IEC 61215 (crystalline silicon PV modules), and USP stability-relevant humidity profiles. The chamber employs a forced-air convection system with high-temperature-rated centrifugal fans and optimized airflow ducting to ensure uniform thermal distribution across the working space, minimizing spatial gradients that could compromise test validity.

Key Features

• Stainless steel inner chamber fabricated by argon arc welding for corrosion resistance and long-term structural integrity under sustained high-humidity exposure;
• Outer enclosure constructed from high-grade cold-rolled steel with powder-coated finish for mechanical durability and aesthetic consistency;
• Digital microprocessor-based PID controller with auto-tuning capability, providing stable setpoint regulation and real-time deviation compensation;
• High-efficiency hot-air circulation system featuring continuous-duty high-temperature fans and aerodynamically optimized internal ductwork;
• Advanced silicone rubber door seal rated for continuous operation at 95°C, ensuring minimal moisture leakage and extended service life;
• Redundant safety architecture including independent over-temperature cutoff, compressor overheat/overcurrent protection, fan thermal shutdown, and low-water-level interlock;
• Modular design supporting custom configurations—non-standard internal dimensions, extended temperature/humidity ranges, or integrated data logging interfaces—upon technical agreement.

Sample Compatibility & Compliance

The GWS-Series accommodates a broad range of sample geometries and material classes, including PCB assemblies, encapsulated semiconductor packages, polymer films, coated metal substrates, and full-size photovoltaic panels (up to GWS-1000 capacity). All models meet the mechanical and climatic test requirements defined in IEC 60068-2-30 (damp heat, cyclic), IEC 60068-2-78 (damp heat, steady state), and ASTM D4332 (conditioning of plastics). For regulated industries, the system supports GLP-compliant operation through optional audit-trail-enabled controllers and calibrated sensor traceability to NIST or CNAS-accredited reference standards. Documentation packages include factory calibration reports, conformity declarations per EN 61000-6-3/6-4 (EMC), and installation qualification (IQ) templates aligned with pharmaceutical and automotive quality systems.

Software & Data Management

While standard configuration includes a standalone digital controller with local display and manual parameter entry, optional RS485/Modbus RTU or Ethernet (TCP/IP) interfaces enable integration into centralized laboratory information management systems (LIMS) or MES platforms. Third-party SCADA-compatible drivers allow real-time acquisition of temperature, humidity, runtime, and alarm status—supporting 21 CFR Part 11-compliant electronic records when paired with validated software environments. Data logging intervals are configurable from 1 second to 60 minutes; stored logs retain timestamps, setpoints, measured values, and event flags (e.g., door open, heater fault), exportable in CSV format for post-test statistical analysis per ISO 16269 or ASTM E29.

Applications

• Accelerated aging of solar PV modules per IEC 61215 and IEC 61701 (salt mist + damp heat combined sequences);
• Electrochemical corrosion screening of printed circuit boards and solder joints under high-humidity thermal stress;
• Validation of conformal coating adhesion and dielectric integrity on automotive ECUs exposed to GMW 14124 Cycle K;
• Stability assessment of pharmaceutical primary packaging under ICH Q1A(R3)-aligned conditions;
• Material compatibility testing of elastomers, adhesives, and laminates per ASTM D570 and ISO 188;
• Qualification of battery enclosures and BMS housings against thermal runaway propagation under humid ambient conditions.

FAQ

What standards does the GWS-Series specifically support for PV module testing?
The chamber satisfies IEC 61730-2 Annex A (damp heat test), IEC 61215 Clause 10.12 (damp heat endurance), and IEC 61701 salt mist + damp heat sequences when operated within its specified temperature/humidity envelope and cycle timing parameters.
Is the controller compliant with FDA 21 CFR Part 11 requirements?
The base controller is not Part 11–validated; however, optional Ethernet-connected controllers with electronic signature, audit trail, and role-based access control can be supplied upon request and deployed under customer-owned validation protocols.
Can the chamber operate continuously at 95°C and 98% RH?
Yes—structural design, insulation performance, and sealing integrity have been verified for uninterrupted operation at maximum rated conditions for durations exceeding 1,000 hours, subject to routine maintenance and ambient cooling capacity.
Are calibration certificates included with shipment?
Each unit ships with a factory calibration report for temperature and humidity sensors, traceable to national metrology institutes. Optional on-site calibration by accredited third parties is available prior to commissioning.
What is the typical lead time for non-standard configurations?
Standard models (GWS-100 to GWS-1000) ship within 6–8 weeks after order confirmation; custom-engineered variants require 12–16 weeks, contingent upon final technical specification sign-off and component sourcing.
