Yuelian YTS-100-40EC Energy-Efficient Temperature and Humidity Controlled Chamber for Adhesive Tape & Thin-Film Testing

Overview

The Yuelian YTS-100-40EC is a vertically oriented, energy-optimized temperature and humidity controlled chamber engineered specifically for the physical property evaluation of pressure-sensitive adhesive tapes, polymer films, laminates, and other thin-film substrates under precisely regulated climatic conditions. Its dual-stage cascade refrigeration architecture enables stable operation down to −55 °C—critical for assessing low-temperature peel adhesion, cold-flow resistance, and dimensional stability in elastomeric and viscoelastic materials. Unlike single-stage systems limited by refrigerant thermodynamic constraints (e.g., R-404A saturation limits near −40 °C), this chamber achieves sub-zero reproducibility without reliance on temperature compensation algorithms or external auxiliary cooling. The integrated carbon-fiber humidification reservoir minimizes surface condensation and eliminates droplet formation—preventing unintended moisture exposure that could compromise test integrity during high-RH cycling or long-duration aging protocols.

Key Features

• Energy-efficient dual-compressor cascade refrigeration: Two 375 W Tecumseh hermetic compressors operate independently or in tandem, reducing peak power draw to ≤750 W during deep-cooling phases—significantly lower than conventional single-stage 1.5 HP (1125 W) alternatives.
• Condensation-free humidification system: Carbon-fiber water tank with low thermal conductivity prevents surface dewing; combined with overflow diversion channels and pressure-relief pathways to ensure no incidental wetting of test specimens.
• Precision 7-inch color touchscreen controller: Supports up to 12 programmable test profiles, each with 120 editable segments; features real-time graphical curve display, alarm history logging, USB data export, and RS-485 Modbus RTU compatibility for integration into centralized lab management systems.
• High-fidelity environmental uniformity: Achieves ±1.0 °C temperature stability and ±1.0 %RH humidity stability across the full working volume, validated per IEC 60068-3-5 methodology for chamber qualification.
• Rugged mechanical construction: Mirror-polished SUS#304 stainless steel interior resists corrosion from solvent vapors and adhesive residues; 100 mm composite insulation (rigid PU foam + glass wool) ensures thermal efficiency and noise reduction.
• Comprehensive safety architecture: Includes redundant compressor overheat/overcurrent protection, high-pressure cut-off switches, dry-burn prevention for humidifiers, and phase-loss detection—all compliant with IEC 61000-6-2 EMC immunity standards.

Sample Compatibility & Compliance

The YTS-100-40EC accommodates standard adhesive tape rolls (≤10 kg per shelf), film reels, and flat-sheet specimens up to 400 mm × 500 mm. Its internal geometry supports ASTM D3330 (peel adhesion), ASTM D1000 (electrical tape performance), ISO 29862 (pressure-sensitive adhesive classification), and GB/T 2792 (Chinese national standard for tape tack and peel). The chamber’s environmental repeatability meets calibration traceability requirements aligned with ISO/IEC 17025:2017 Clause 6.4.10 for testing equipment used in accredited laboratories. While not certified to UL or CE as a standalone medical device, its electrical and mechanical design conforms to IEC 61010-1 safety principles for laboratory equipment.

Software & Data Management

The embedded controller provides native data logging at user-selectable intervals (1–600 seconds), storing temperature/humidity readings, alarm events, and program execution status internally for ≥30 days. Data can be exported via USB flash drive in CSV format for post-processing in MATLAB, Python (Pandas), or LIMS platforms. Optional PC-based software (supplied free of charge) enables remote monitoring, script-based profile automation, and audit-trail generation—including operator ID tagging and timestamped parameter changes—supporting GLP/GMP documentation needs. All logged data retains immutable timestamps synchronized to NTP servers when connected to Ethernet-enabled gateways.

Applications

• Evaluating low-temperature brittleness and cohesive failure modes of acrylic, rubber-based, and silicone PSA formulations per ASTM D6202.
• Accelerated aging studies of optical films and barrier coatings under 85 °C/85 %RH stress conditions (JEDEC JESD22-A101).
• Studying humidity-induced dimensional change and interlayer delamination in multilayer laminates used in flexible packaging.
• Validating storage stability of medical-grade adhesive patches across regulatory climate zones (ICH Q1A, Q5C).
• Supporting QC/QA workflows in ISO 9001-certified manufacturing facilities where environmental conditioning precedes tensile, shear, or loop tack testing.

FAQ

What is the lowest operational temperature achievable with full humidity control?
The chamber maintains 20–98 %RH capability down to −40 °C. Below that, dehumidification is disabled to prevent ice accumulation; however, dry-cold testing to −55 °C remains fully supported.
Does the controller support 21 CFR Part 11-compliant electronic signatures?
The base controller does not include electronic signature functionality; however, the optional PC software package supports role-based access control, audit trails, and digital signature capture when deployed on validated Windows OS environments.
Can the unit be integrated into a building management system (BMS)?
Yes—via RS-485 Modbus RTU output, the chamber transmits real-time temperature, humidity, alarm status, and setpoint values to third-party BMS platforms using standard register mapping.
Is calibration certification included with shipment?
A factory-as-tested report (including temperature/humidity uniformity verification at three load points) is provided. Full ISO/IEC 17025-accredited calibration requires engagement with an external accredited provider.
What maintenance intervals are recommended for long-term reliability?
Compressor oil inspection every 24 months; refrigerant leak check annually; humidifier tank cleaning weekly; air filter replacement quarterly; and full controller firmware update verification semiannually.
