Thermal Shock Test Chamber

Thermal shock test chambers, also known as high-low temperature shock test chambers or temperature shock test chambers, are categorised structurally into two-chamber and three-chamber configurations. Primarily employed across aerospace, automotive manufacturing, naval armaments, electronics, electrical engineering, and instrumentation industries, these chambers subject materials and components used in these sectors to temperature variation testing, Thermal shock testing and alternating high-low temperature impact testing assess the tolerance of metals, plastics, rubber, electronics, new materials, and composites to consecutive exposure to extreme high and low temperatures within the shortest possible timeframe. This evaluates the chemical alterations or physical damage incurred by specimens due to thermal expansion and contraction.

1. Imported from South Korea, the TEMI8226 colour touchscreen display shows set parameters, test curves, operating time, and heater status, alongside measured and set values. It supports USB data export for records and operational curve extraction.

2. The refrigeration core employs a dual-stage cascade air-cooled system comprising two imported 2×6HP IFC Tecumseh hermetically sealed compressors. All circulation fans utilise imported brands (EBM 4E-300-Z), with environmentally sound refrigerants (R23/R404) employed;

3. Employs novel PWM cold control technology for energy-efficient low-temperature operation. During sub-zero conditions, the heater remains inactive. PWM technology regulates refrigerant flow rate and direction within the refrigeration unit, adjusting three-way flow through the refrigeration line, cold bypass line, and hot bypass line to automatically maintain constant chamber temperature, reducing energy consumption by 40%;

4. Imported low-noise forced-air fans with unique duct design ensure uniform air distribution within the chamber, guaranteeing temperature homogeneity. The refrigeration system employs a classic configuration proven stable through years of market testing, delivering safety and reliability;

5. Supports remote network control operation (Ethernet, optional). Enables effortless remote control, programme setting, parameter viewing, and fault troubleshooting;

6. The control system incorporates comprehensive self-diagnostic functions, automatically performing self-checks upon startup while displaying current equipment status and alerts;

7. Single-screen display of set parameters, current programme number, elapsed/remaining time, heater/humidifier operational status, and remaining cycle count. Capable of visualising programme curves, switching freely between fixed-value and programmed control modes, and language selection (Chinese/English). Performs automatic fault detection, display, and alarm activation.

8. Scheduled start/stop functionality. Preserves data curves during power outages following programmed completion.

9. Comprehensive communication system enabling real-time experimental curve analysis, with RS232/USB (select one) data storage and export connectivity;

10. Automatic return of test specimens to ambient temperature upon test completion to prevent frost/condensation formation;

11. Servo refrigerant flow control technology achieving over 30% energy savings;

12. Automatic parameter saving during emergencies with power-restoration capability, alongside sensor self-diagnosis, over-temperature, and fault alarm functions;

13. Inner chamber constructed from 304 brushed stainless steel; outer casing from premium cold-rolled steel plate with electrostatic powder coating for durable, anti-static finish.
