DRETOP THS-C1000-II High-Low Temperature Environmental Test Chamber

Overview

The DRETOP THS-C1000-II High-Low Temperature Environmental Test Chamber is an engineered precision platform for accelerated environmental stress testing of industrial components and finished products under controlled thermal extremes. Designed in accordance with IEC 60068-2-1 (Cold), IEC 60068-2-2 (Dry Heat), and ISO 16750-4 (Road Vehicles – Environmental Conditions), the chamber delivers reproducible, traceable thermal profiles across a wide operating range of -60 °C to +150 °C. Its dual independent control architecture separates heating, cooling, and airflow subsystems—minimizing cross-interference and ensuring stable setpoint adherence during dynamic ramp-and-soak cycles. The chamber’s 1000 L internal volume (1000 × 1000 × 1000 mm) accommodates large-format automotive modules, aerospace subassemblies, or multi-unit electronics racks, while its optimized air distribution system—featuring high-efficiency centrifugal fans and symmetrically arranged ductwork—meets ASTM E145 Class B uniformity requirements (<2 °C deviation across load zone).

Key Features

• Full-color 7-inch TFT touchscreen HMI with bilingual (English/Chinese) interface, hierarchical user permissions (up to 10 accounts), and password-protected parameter editing to prevent unauthorized configuration changes.
• Advanced programmable logic controller supporting up to 100 segments per program, 100 stored programs, and flexible sequence operations including jump-to-step, hold, loop, and transition to constant-value mode.
• Independent PID-tuned heating (NiCr alloy resistive elements) and refrigeration (imported hermetic scroll compressor, R404A/R23 cascade system) circuits—enabling precise decoupled control of ramp rates (1–3 °C/min heating; 0.7–1 °C/min cooling) and minimizing thermal overshoot.
• Double-glazed, electrically heated observation window with integrated LED illumination—preventing condensation and enabling real-time visual inspection without thermal disturbance.
• Stainless steel 304 interior with radius-corner construction, removable adjustable shelves, and silicone door seal rated for continuous operation from -60 °C to +150 °C without hardening or adhesion loss.
• Comprehensive safety suite: over-temperature cut-off (mechanical backup sensor), compressor discharge temperature monitoring, fan failure detection, ground-fault circuit interruption (GFCI), and automatic power recovery with configurable restart delay.
• Standard 50 mm diameter test port (with EPDM plug) for live signal, power, or pneumatic feedthrough—compatible with external data acquisition systems and in-situ monitoring probes.

Sample Compatibility & Compliance

The THS-C1000-II is validated for testing non-hazardous solid and assembled products per IPC-J-STD-004B (flux residue evaluation), AEC-Q200 (passive component qualification), and MIL-STD-810H Method 502.7 (low temperature) / Method 501.7 (high temperature). It supports static and dynamic thermal cycling protocols required by JEDEC JESD22-A104F and IATF 16949 clause 8.5.1.2 for production part approval process (PPAP) validation. The chamber’s stainless steel interior and sealed airflow path meet basic cleanroom compatibility requirements (ISO Class 8 equivalent), while its electromagnetic compatibility complies with EN 61326-1 for laboratory use. Optional humidity control (30–95% RH, ±3–5% RH accuracy) extends applicability to combined temperature-humidity stress testing per IEC 60068-2-30.

Software & Data Management

Embedded firmware enables local data logging at user-defined intervals (1–600 seconds), with onboard storage for ≥30 days of timestamped temperature/humidity/program status records. Export formats include CSV and native .DRE files convertible to Excel-compatible spreadsheets or time-series plots via DRETOP’s free PC software (v4.2+). For regulated environments, optional 21 CFR Part 11-compliant audit trail functionality—including electronic signatures, immutable event logs, and role-based access control—is available upon configuration. Remote access is implemented via HTTPS-secured web server supporting simultaneous connections from up to five clients (desktop, tablet, smartphone), with synchronized UI mirroring and real-time alarm push notifications. Firmware updates are performed over-the-air or via USB drive without interrupting active test sequences.

Applications

This chamber serves as a core reliability assessment tool across multiple sectors: validating thermal endurance of EV battery management systems (BMS) and power electronics under ISO 16750-4 cold soak and heat soak conditions; qualifying LED lighting modules for outdoor deployment per IEC 62717; verifying solder joint integrity in PCB assemblies using JEDEC J-STD-020D moisture sensitivity level (MSL) preconditioning; conducting accelerated aging of polymer enclosures and gaskets in accordance with ASTM D573; and supporting R&D-stage material characterization for aerospace composites under extreme thermal gradients. Its robust mechanical design and factory-calibrated sensors make it suitable for both QA/QC labs and long-duration validation campaigns under GLP or GMP-aligned quality systems.

FAQ

What is the maximum allowable sample mass for thermal stability testing in the THS-C1000-II?
The chamber is rated for a maximum thermal load of 15 kg at steady-state conditions. For dynamic ramp tests, total thermal mass should remain below 8 kg to maintain specified heating/cooling rates and uniformity.
Does the unit comply with CE or UKCA marking requirements?
Yes—fully compliant with EU Machinery Directive 2006/42/EC, Electromagnetic Compatibility Directive 2014/30/EU, and Low Voltage Directive 2014/35/EU. Declaration of Conformity and technical file documentation are supplied with each unit.
Can the chamber be integrated into a centralized lab monitoring network?
Yes—standard Modbus RTU (RS485) and optional Modbus TCP/IP (Ethernet) protocols enable seamless integration with SCADA, LIMS, or MES platforms. OPC UA support is available under custom firmware configuration.
Is calibration certification included with shipment?
A factory-issued NIST-traceable temperature calibration report (at three points: -40 °C, 25 °C, +100 °C) is provided. On-site IQ/OQ validation services and annual recalibration contracts are offered through DRETOP’s global service partners.
What maintenance intervals are recommended for sustained performance?
Compressor oil and refrigerant levels should be verified annually; air filters require cleaning every 3 months; door gasket integrity and heater resistance should be inspected semiannually. Full preventive maintenance is advised every 24 months or after 5,000 operational hours.
