LabCompanion C-Series Environmental Test Chamber

Overview

The LabCompanion C-Series Environmental Test Chamber is a precision-engineered thermal stress testing system designed for rigorous temperature cycling, steady-state thermal exposure, and combined temperature-humidity conditioning in industrial quality assurance, electronics reliability validation, automotive component qualification, and materials science laboratories. Built upon the principles of forced-air convection thermodynamics and closed-loop PID-controlled refrigeration, the chamber delivers repeatable, traceable, and standards-compliant environmental simulation across an extended operational range—from ultra-low temperatures of −70 °C to elevated thermal extremes of +150 °C. Its dual-stage (cascade) refrigeration architecture enables stable sub-zero operation without cryogenic media, while the optimized airflow design—featuring stainless steel centrifugal impellers and extended-shaft circulation—ensures uniform thermal distribution (≤2 °C deviation) and minimal spatial gradient per IEC 60068-3-5 and ASTM E145 Class B requirements.

Key Features

• Modular temperature range configuration: Select from five base variants (H/R/L/S/U) covering −70 °C to +150 °C, each validated for long-term stability under continuous operation.
• High-fidelity microprocessor touch controller with real-time data logging, programmable multi-step profiles (up to 99 segments), and intuitive graphical interface compliant with IEC 61000-4-30 EMC immunity standards.
• Dual-stage refrigeration system utilizing imported hermetic compressors (Tecumseh-licensed), multi-plate evaporators, and environmentally compliant R404A/R23 refrigerant blends—optimized for low-noise, low-vibration performance and extended service life.
• Double-wall construction: Inner chamber of brushed SUS304 stainless steel; outer shell of powder-coated cold-rolled steel with oil-pattern finish—resistant to corrosion, mechanical abrasion, and thermal fatigue.
• Robust thermal insulation: 120 mm composite layer comprising rigid polyurethane foam (λ ≈ 0.022 W/m·K) and mineral rock wool—achieving thermal transmittance (U-value) <0.25 W/m²·K per EN ISO 6946.
• Comprehensive safety architecture: Independent over-temperature cut-off (mechanical backup), compressor high-pressure switch, ground-fault circuit interrupter (GFCI), and fast-acting fusing—all independently certified to UL 61010-1 and IEC 61010-1.

Sample Compatibility & Compliance

The C-Series accommodates diverse sample geometries and material classes—including PCB assemblies, polymer composites, battery cells, aerospace fasteners, and medical device housings—within its standardized internal volumes (400 L to 1000 L). All models meet structural and operational criteria outlined in MIL-STD-810H Method 501.7 (High Temperature), Method 502.7 (Low Temperature), and Method 503.7 (Temperature Shock), as well as ISO 16750-4 for automotive electronics. Optional humidity control modules comply with IEC 60068-2-78 (damp heat, cyclic) and ASTM D4329 (UV + condensation exposure when integrated with UV irradiation options). The chamber’s construction materials and electrical design conform to RoHS 2011/65/EU and REACH Annex XVII restrictions.

Software & Data Management

Equipped with LabCompanion’s proprietary TC-Link™ software suite (Windows-compatible), the C-Series supports full remote monitoring, alarm notification via SMTP/SNMP, and audit-trail-enabled data export in CSV and PDF formats. The controller firmware implements time-stamped event logging—including setpoint changes, door openings, alarm triggers, and calibration adjustments—with optional 21 CFR Part 11 compliance modules available for regulated environments (pharmaceutical QC, medical device validation). Data integrity is preserved through non-volatile memory retention (>10 years), password-protected user roles (Operator/Engineer/Administrator), and encrypted USB export functionality.

Applications

• Accelerated life testing of lithium-ion battery modules under thermal stress (UN 38.3 T1–T5 protocols)
• Thermal cycling validation of automotive ECUs per AEC-Q200 Grade 1/2 specifications
• Material coefficient of thermal expansion (CTE) characterization via dimensional metrology integration
• Pre-conditioning of optical components prior to laser-induced damage threshold (LIDT) measurement
• Stability assessment of adhesives, encapsulants, and conformal coatings per IPC-9701
• Environmental screening of avionics hardware per DO-160 Section 4 and 5

FAQ

What is the standard warranty period for the C-Series chamber?
LabCompanion provides a 24-month limited warranty covering parts and labor for defects in materials and workmanship under normal laboratory use.
Can the chamber be integrated into a centralized lab monitoring network?
Yes—Ethernet (RJ45) and RS485 interfaces support Modbus TCP/RTU communication for SCADA and MES integration.
Is third-party calibration certification included with delivery?
Factory calibration reports (traceable to NIM, China) are provided; ISO/IEC 17025-accredited calibration certificates are available as an optional add-on.
Does the system support rapid temperature transitions between extreme setpoints?
Standard ramp rates are 0.7–1 °C/min; optional high-speed configurations achieve up to 10 °C/min using enhanced refrigerant charge and auxiliary heating/cooling circuits.
Are custom internal fixtures or test ports available?
Yes—customizable stainless steel shelves, cable access ports (with silicone grommets), and DIN-rail mounting kits can be specified at order entry.
