Large Capacity Thermal Shock Chamber

Custom Product

Today, the automotive industry accelerates electronic multi-functions. According to this trend, safety standards such as ISO26262 and IEC61508 require high environmental stress that is generated by thermal shock chambers for higher reliability of vehicle equipments.

It is available from 1,100-liter, 1,650-liter, and 2,200-liter models. Unlike conventional chambers, this enables thermal shock testing of large automobile parts (e.g. Li-ion battery modules, electric turbochargers, intercoolers, radiators, and inverters for vehicles), large flat panel displays, and relatively large products that could not be previously tested due to their size or weight. This is ideal for customers who need to quickly test large amounts of specimens, such as for quality inspection during the production process.

Large test area

Available following three large-capacity models.

  • TSA-1100-W 1000(W)×1100(H)×1000(D)mm
  • TSA-1650-W 1500(W)×1100(H)×1000(D)mm
  • TSA-2200-W 2000(W)×1100(H)×1000(D)mm
TSA series common operability
Basic control method is common by using the same interactive touch panel instrumentation as that of the standard TSA series for easy operation.
Considerable design for installation
Large-capacity chambers bring with them the problems of installation space. This chamber has been designed to reduce protrusions as much as possible. The chamber consists of separable unit structure, which facilitates installation work. In addition, the refrigerator can be accessed from the rear for ease of maintenance.
Easy specimen carry-in & carry-out

In the testing of some specimens, such as battery modules, the weight of specimens increases since not only is the size of specimen large but also the loading capacity is large.

  • Designed lower floor of the test area by placing the hot chamber on top and the cold chamber in the rear.
  • Openings for a specimen loading hand lift truck.
  • Doorstopper prevents accidents when closing the door during operation.

Safety devices
Various safety devices are available in case og testing second batteries and fuel cells that are flammable or gaseous.

Typical devices:

  • Pressure release vent
  • Gas detector
  • Forced ventilation system
  • CO2 gas extinguisher
  • Safety lock mechanism

* Be sure to install the safety device if the chamber is used for charge-discharge testing or testing Li-ion battery packs or Li-ion battery modules.
