3-Zone Thermal Shock Tester

3-Zone Thermal Shock Tester


Thermal Shock Tester















The 3-zone thermal shock testing chamber has a high-temperature zone, a low-temperature zone, and a testing zone. It is used to test the degree to which a material can endure in a continuous environment of high temperature and low temperature in an instant so as to test its chemical changes or physical damage caused by thermal expansion and contraction in a short period of time.

Cooling System

  1. Selected compressor: imported Germany Bitzer hermetic compressor with lower noise, more stable operation and better performance;
  2. Standardization of refrigeration unit modules, divided into three modules: partial assembly, final assembly, and condensing evaporator; establish a pipe bending language manual to ensure the uniformity of pipeline production;
  3. Standardized modules are easy to install, repair, and maintain;
  4. All pipelines are welded with nitrogen protection to ensure that the inside of the pipeline is not oxidized, and
  5. the surface of the weld is coated with an anti-corrosion protective layer;
  6. Adopt HFC (fluorocarbon) refrigerants with zero ozone depletion coefficient;
  7. The refrigeration system adopts intelligent control, which can adapt to a wide range of loads and consume less power;
  8. All condensers are equipped with filter devices to protect the normal operation of the unit;
  9. Adopt components of international famous brands;


Compliance with ASTM G53-77 specifications GB, GJB, MIL, ASTM, CNS, IEC, JIS, AATCC, DIN, Fed Test, BS and SAE.


  1. Features a static three-chambers product structure;
  2. It is equipped with a super large window design, facilitating convenient observation of test sample conditions within the chamber;
  3. The door lock design utilizes leverage principles, ensuring easy operation and effective sealing;
  4. High wind speed guarantees uniform exposure of samples and enhances overall box uniformity;
  5. The chamber comes standard with a defrosting device, featuring automatic and manual defrosting functions;
  6. The box door is equipped with a limit switch that triggers automatic alarms and stops when opened;
  7. The inner box is constructed with SUS304 stainless steel plate, while the outer box is made of cold-rolled steel plate with baking paint or SUS304 stainless steel;
  8. To ensure safety, the system, cooling system, and electrical system of the chamber are modularized and arranged separately.
