Key Features
- Precision control: PID with auto-tuning for tight stability (about ±0.3°C, ±2% RH).
- Uniformity: Optimized airflow for typical ±1.0°C and ±3% RH across the workspace.
- Build quality: SUS304 stainless-steel interior, high-density insulation, heated anti-fog window, LED lighting, airtight gaskets.
- Safety: Over-temperature cut-offs, compressor high-pressure protection, humidifier dry-run prevention, low-water alarms, door interlock, emergency stop.
- Interface and data: Touch-screen HMI, multi-step profiles, Ethernet/USB export, remote monitoring, event logs, and trend views.
Performance and Working Range
- Standard ranges: −40°C to +150°C and 20%–95% RH.
- Options: Extend to −70°C to +180°C and higher ramp capability.
- Typical ramp rates: Up to 3°C/min standard; 5°C/min optional.
- Stability and uniformity: About ±0.3°C and ±2% RH stability; typical ±1.0°C and ±3% RH uniformity.
- Rapid pull-down and recovery to reduce cycle time and protect profile integrity.
Sizes and Configurations
- Benchtop (80–150 L): Compact footprint for small assemblies, connectors, and polymer coupons; single-phase power options.
- Floor-standing (300–1000 L): Larger capacity, robust airflow, and dual-stage refrigeration for deeper low temperatures.
- Custom walk-in: Site-specific volumes, integrated data acquisition, and on-site installation for oversized parts.
Core Systems
- Refrigeration: Energy-efficient compressors, eco-friendly refrigerants (e.g., R404A/R449A), hot-gas bypass, optimized heat exchangers; cascade options for deep-low temperatures.
- Humidity control: Stainless-steel steam humidifier and precision RH sensing, refrigeration-assisted dehumidification; ultrasonic optional.
- Insulation and sealing: High-density insulation and engineered door seals maintain tight control and improve energy use.
Applications and Standards
Use the chamber for temperature cycling, damp heat endurance, and stability conditioning across electronics, PCBs, sensors, connectors, polymer specimens, wire and cable insulation, packaging materials, and automotive/aerospace parts.
It supports preconditioning of plastics per ASTM D618, packaging conditioning per ASTM D4332, and common humidity and temperature methods in IEC 60068-2-1/-2/-78. Programmable ramps, dwells, and cycles with data logging aid method validation and audits.
Selection Tips
- Define the lowest/highest temperature and RH, plus required ramp rates.
- Match chamber volume to sample size, fixtures, and airflow needs.
- Confirm uniformity needs across shelves for multi-sample runs.
- Choose ports, shelves, windows, and fixturing that fit your instrumentation.
- Consider energy options such as inverter drives or low-GWP refrigerants.
