Overview
JIANGKAI NBC-LC-150 (-60 ℃) Thermal Shock Test Chamber is mainly used to test the tolerance of materials in extremely high temperature or extremely low temperature instantaneous alternating environment, simulating chemical changes or physical damage caused by thermal expansion and contraction of products. The equipment adopts PID automatic Control system to ensure the accuracy and Reliability of testing, conforms to a number of national standards and international norms, and is suitable for mass testing and product improvement in metal, plastic, rubber, electronics and other industries.
Features
1. Adopt programmable color screen TEMI8226S Touchscreen controller imported from Korea, intuitive operation, with data saving, reservation switch and experimental Linear dispersion analysis functions.
2. Equipped with RS232, USB Data storage interface, support remote monitoring and data export.
3. Using servo refrigerant Flow rate control technology and PWM cold control technology, effective energy saving is more than 30%, and energy consumption can be reduced by 40% under low temperature conditions.
4. Adopt pure aluminum fin evaporator and multi-stage membrane air heat exchanger to reduce energy storage time and improve heat exchange efficiency.
5. Equipped with Dual-Box and Three-Box test functions, in line with test specifications, the experiment is carried out in a cycle, and defrost once every 5 days without affecting the Impact time.
6. At the end of the test, the product to be tested will automatically return to normal temperature to avoid frost and dew condensation protection mechanism.
7. The refrigeration system adopts the dual cascade Water-Cooled refrigeration system composed of the French Taikang fully enclosed Compressor, which operates stably.
8. Built-in multiple Safety protection measures, including over-temperature, overvoltage, overload, leakage and other protection functions.
Principle
The equipment adopts the forced ventilated internal equilibrate temperature control method (BTC). When the refrigeration system works continuously, the Control system controls the heater output through PID operation according to the set temperature to achieve dynamic equilibrate. The refrigeration system adopts a binary cascade cycle, including high temperature and low temperature refrigeration cycles. Energy is transferred through evaporative condenser, and the principle of inverse carrot cycle is used to achieve cooling. The air circulation device performs effective heat exchange through a long-axis centrifugal ventilator to improve the airflow to improve Temperature Uniformity.

4. The equipment automatically performs high and low temperature Impact testing, and automatically returns the sample to normal temperature after the test.
5. View and save experimental data and Linear dispersion through the controller or Interface.
Notice
* Ambient Temperature of the equipment should be kept between 5 ℃ and 40 ℃, Environmental humidity ≤ 80% R.H.
* Guaranteed performance conditions are Ambient Temperature ≤ 30 ° C and no condensation to ensure a minimum temperature of -60 ° C.
Safety protection is provided, but the refrigeration system, electrical components and protective devices need to be checked regularly.
Sample stand test, do not move the sample chamber while the equipment is running.
* The defrosting cycle is about once every 5 days, and the defrosting time is about 2 hours, which does not affect the impact test time.
* The power requirements are AC380V, 50~ 60Hz, Power 10~ 15KW, need to ensure stable power supply.
The left side of the device is equipped with a φ 50mm lead hole for external connection.
