Beier collaborated closely with the client through multiple technical meetings to deconstruct specific testing scenarios, required parameters, and on-site spatial constraints for this large-scale military standard sand and dust testing chamber. By integrating industry standards with prior engineering experience, our project team iteratively refined the solution design. Every detail, from dimensional engineering to functional configuration, was verified with the client prior to manufacturing to achieve full compliance with national military testing standards (GJB150.12).
| Temperature Range | RT~+80°C (adjustable) |
| Temperature Deviation | ≤±2.0℃ |
| Temperature Fluctuation | ≤±0.5℃ |
| Humidity Range | ≤30%RH |
| Compliance | Dust/sand concentrations and test procedures strictly comply with GJB 150.12. |
| Structural Design | The circular/annular structure eliminates dead corners, preventing sand and dust accumulation commonly found in rectangular chambers. |
During final acceptance, the client was welcomed by Chairman Hua Ming and accompanied to the manufacturing site for on-site inspection and equipment verification.
