Precision Thermal Shock Chambers | Reliable Performance for Extreme Temperature Variation Testing

Thermal Shock Chambers are high-performance environmental testing devices designed to simulate rapid temperature changes between extreme hot and cold conditions. They are essential for evaluating product durability, performance, and reliability when exposed to sudden thermal transitions. These chambers eliminate manual testing, providing automated, consistent, and highly accurate results that meet global testing standards.

At their core, Thermal Shock Chambers create controlled, repeatable environments to assess the thermal resistance and material stability of components, assemblies, and finished products. They are widely used in industries such as electronics, automotive, aerospace, defense, pharmaceuticals, and research laboratories to ensure products can withstand temperature extremes without compromising quality or safety.

FAQ's

What materials are used in chamber construction?
Typically stainless steel (SS 304 or 316) for interiors and insulated mild steel for exteriors.

Are these chambers suitable for PCB testing?
Yes, they are ideal for testing PCB durability under thermal stress.

What’s the difference between 2-zone and 3-zone chambers?

2-zone chambers have hot and cold sections, while 3-zone adds a room temperature section for complex testing.


Which industries need thermal shock testing?

Industries like electronics, automotive, aerospace, and defense rely on this testing.


What is a Thermal Shock Chamber used for?

It is used to test a product's resistance to sudden and extreme temperature changes.


What are the various types of Thermal Shock Chambers?

In Vertical Orientation Thermal Shock Chamber has two independently controlled hot and cold zones, a single product carrier moves between each zone which results in dramatic temperature changes. Also, it has the advantage that it uses fewer floor spaces making it a better deal for smaller labs.
In Horizontal Orientation Thermal Shock Chamber has three side-by-side independent zones hot, ambient & cold. This chamber is used for accomplishing by programing the product carrier which tends to transfer the product from hot to cold and back again, by eliminating dwell in the ambient zone.
A Double Duty Thermal Shock Chamber is positioned in cold zones between two hot zones which are aligned vertically top and bottom. At least one product carrier is always occupied by the cold zone. This design makes efficient use of the chamber cooling system which provides increased product testing over standard thermal shock designs.

How does Thermal Shock Chamber Works?

The temperature of the chamber is controlled by an electric heater or a refrigeration device. Researchers spray a salt solution through a nozzle within the chamber to mimic the corrosive effect of the sea, for example, creating a fine mist that covers the whole product.

What is the meaning of thermal shock?

Thermal shock is a form of mechanical load that occurs quickly. A mechanical load is described as a load caused by a rapid change in temperature at a specific point. It can also be applied to a thermal gradient, in which different sections of an object expand at different rates.
