What is a Two-Zone Thermal Shock Chamber ?
2-Zone Thermal Shock Chambers from ATMARS consist of two separately controlled hot and cold zones (one atop the other) with product being transferred vertically by a pneumatic basket for rapid product temperature changes. The conditioned air is pre-cooled or pre-heated beyond the setpoint, allowing quicker recovery of the desired condition after transfer.
The induced thermal stresses can reveal hidden manufacturing defects in electronic sub-assemblies and other components by the expansion and contraction of critical parts, ideal for testing to find product flaws before they reach your customers.

General Performance of ATMARS 2 ZONE Thermal Shock Test Chambers
AS2 Series Two Zone (Hot/Cold) Vertical Layout - direct hot/cold transfer of basket by a pneumatic elevator.
Our standard two-zone thermal shock chambers models workspace volumes include: 48L, 72L, 80L, 100L, 150L and 216L. And interior dimensions can be customized according to specimen sizes and your testing requirements.
Temperature Range:
- Hot zone to +180℃ (356° F)
- Cold zone to -75℃ (-103° F)
- Other temperature range available
High temperature exposure: +150℃ (302° F)
Low temperature exposure:
Type A: -40℃ (-40° F)
Type B: -55℃ (-67° F)
Type C: -65℃ (-85° F)
Recovery time for mechanical refrigeration : ≤ 3minutes
High / Low temperature exposure time: 30minutes
Automatic transfer of test specimens between hot zone and cold zone
Basket transfer time within 10 Sec.
An ATMARS application engineer can assist you in selecting the chamber configuration and size that is most economical for your testing needs.
