What is a Walk-In Chamber?
Walk-In Chambers from ATMARS serves as an ideal test site for large components, assemblies, and finished products. We manufacture both Panel (modilar) Walk-In Chambers and Solid (welded) Walk-In Chambers and can be configured as a temperature chamber or a temperature humidity chamber. A Panel Walk-In Chamber is made from lightweight insulated panels for fast and easy installation.
| Technical Specifications of AHW-8 SERIES Walk-in Environmental Chambers Performance is based on ambient temperature +20 ℃ or circulating water temperature +25 ℃, empty load no specimen. |
