ESS Thermal Shock Chambers (TSV, TSH, TSD Series)

Russells’ air-to-air thermal shock chambers meet the demands of today’s environmental stress screening with proven performance in installations around the world. Our direct transfer method between hot and cold is an economical way to achieve rapid part temperature change for ESS or thermal shock. A Russells application engineer can assist you in selecting the configuration, size, and options that best suit your needs.

About ESS Thermal Shock Chambers

ESS is a means of screening products to expose defective parts or process problems that can’t be detected upon visual inspection or electrical testing. Developed to detect product defects and production flaws in electronics manufacturing, ESS uses thermal cycling or vibration to expose failures. Environmental stress screening chambers can be used as part of the manufacturing process, or they can be used in new product qualification testing.
