Micono GDW-050 High-Low Temperature Alternating Environmental Test Chamber

Overview

The Micono GDW-050 High-Low Temperature Alternating Environmental Test Chamber is an engineered platform for controlled thermal stress evaluation of industrial components and materials under defined climatic conditions. It operates on the principle of forced-air convection with dual-stage refrigeration and electric heating, enabling precise simulation of temperature extremes and transition profiles required in environmental qualification testing. Designed for compliance with international test standards—including IEC 60068-2-1 (Cold), IEC 60068-2-2 (Dry Heat), MIL-STD-810H Method 502.7, and GJB 150.3A/150.4A—the chamber supports both steady-state and cycling protocols. Its architecture integrates thermodynamic stability, mechanical robustness, and operational repeatability, making it suitable for validation laboratories, R&D centers, and quality assurance departments in aerospace, automotive electronics, consumer appliance manufacturing, and defense electronics sectors.

Key Features

• Configurable temperature range spanning −60 °C to +200 °C, selectable at time of order to match application-specific thermal envelope requirements.
• High-fidelity thermal control system featuring PID algorithm with auto-tuning capability, delivering ±0.5 °C stability and ±2 °C uniformity across the full working volume (700 × 800 × 900 mm).
• Internally lined with electropolished SUS304 stainless steel—resistant to corrosion, thermal fatigue, and cleaning agents—ensuring long-term integrity and contamination-free testing environments.
• Dual-circuit refrigeration system utilizing a hermetically sealed French Tecumseh compressor and imported OEM expansion valves, condensers, and evaporators for consistent cooling performance and extended service life.
• Conductive-heated, double-glazed observation window with integrated LED illumination enables real-time visual monitoring without compromising thermal isolation or introducing condensation.
• One standardized Φ50 mm cable port with high-temperature silicone gasket allows safe integration of external instrumentation, power feeds, or sensor leads without leakage or thermal bridging.
• Comprehensive safety architecture includes redundant over-temperature cutoffs, phase sequence protection, earth leakage circuit interruption, and compressor high-pressure shutdown—all logged and accessible via the controller interface.

Sample Compatibility & Compliance

The GDW-050 accommodates samples up to 60 kg (static load) and dimensions compatible with its internal cavity. Its thermal profile fidelity supports testing per ASTM D3418 (thermal transitions of polymers), ISO 16750-4 (road vehicles—electrical loads), and USP (pharmaceutical packaging stability). The chamber meets GB/T 10586–2006 (Environmental Test Chambers General Requirements), GB/T 2423.1–2023 (Cold Testing), GB/T 2423.2–2023 (Dry Heat Testing), and aligns with GLP-compliant data traceability when paired with optional audit-trail-enabled software. All electrical components—including Schneider and Merlin Gerin contactors, relays, and circuit breakers—comply with IEC 60947 and CE marking directives.

Software & Data Management

The standard RKC or Fuji controller provides local setpoint programming, ramp-soak cycling, real-time curve display, and event logging (up to 10,000 records). Optional PC-based software enables remote supervision, automated report generation (PDF/CSV), and integration into LIMS or MES platforms via Modbus RTU or Ethernet/IP. When configured for 21 CFR Part 11 compliance, the system supports user-level access control, electronic signatures, and immutable audit trails—including operator ID, timestamp, parameter changes, and alarm acknowledgments—meeting FDA-regulated validation requirements for pharmaceutical and medical device testing.

Applications

• Qualification of printed circuit boards (PCBs) and embedded controllers under thermal shock and storage conditions per IPC-9701 and JEDEC JESD22-A104.
• Material aging studies of elastomers, adhesives, and composite laminates under prolonged exposure to extreme cold or elevated temperatures.
• Pre-conditioning of lithium-ion battery modules prior to safety testing (UN 38.3, IEC 62133).
• Validation of automotive ECUs against ISO 16750-4 temperature profiles for engine bay, cabin, and under-hood environments.
• Stress screening of avionics hardware per DO-160G Section 4 (Temperature Variation) and Section 5 (Temperature Altitude).

FAQ

What temperature ranges are available for the GDW-050 model?

The GDW-050 is offered in three low-temperature options (−20 °C, −40 °C, or −60 °C) and three high-temperature limits (100 °C, 150 °C, or 200 °C); selection is finalized during ordering based on intended test standards.

Does the chamber support programmable temperature cycling?

Yes—up to 99 segments per cycle, with independent ramp rate, soak duration, and setpoint definition; cycles may be repeated up to 999 times with automatic termination logic.

Is third-party calibration certification included?

Factory calibration is performed using NIST-traceable PT100 reference probes; ISO/IEC 17025-accredited calibration certificates are available as an add-on service.

Can the GDW-050 be integrated into an existing laboratory automation network?

Standard RS485 Modbus RTU is provided; optional Ethernet/IP, Profibus DP, or OPC UA gateways enable seamless SCADA or MES connectivity.

What is the warranty coverage and service response time?

The unit carries a 12-month parts-and-labor warranty from commissioning date; technical support is available within 2 business hours, with on-site service dispatch scheduled within 3–5 business days for covered regions.
