What is a Three -Zone Thermal Shock Chamber ?
3-Zone Thermal Shock Chambers from ATMARS has three side-by-side independent zones: hot, ambient, and cold. The addition of the ambient zone allows for three zone testing, which is a requirement of some military standards.
General Performance of ATMARS Three Zone Thermal Shock Test Chambers
AS3 Series Three Zone (Hot/Ambient/Cold) Horizontal Layout (side by side) - direct hot/cold transfer with selectable ambient temperature dwell required for some MIL-STD's.
Our standard three-zone thermal shock chambers models workspace volumes include: 72L, 100L, 150L, 200L, 252L, 300L and 480L. 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 : ≤ 5minutes
High / Low temperature exposure time: 30minutes
An ATMARS application engineer can assist you in selecting the chamber configuration and size that is most economical for your testing needs.
