The MIL Sand and Dust Chamber is engineered to simulate desert environments for testing military equipment and devices according to MIL-STD-810G standards. It replicates desert conditions by blowing dust as per Procedure I, with concentrations of 10 ± 7 g/m³ and air velocities of 1.5 to 8.9 m/s, and sand as per Procedure II, with concentrations of 0.18 to 2.2 g/m³ and air velocities of 18 to 29 m/s. The chamber features automatically controlled sand and dust feeders, and air velocity is managed via a variable frequency drive (VFD). Humidity levels are maintained below 30% RH, and all parameters are programmable through a Graphite touchscreen with Siemens SIMATIC controllers.
Operating in a temperature range of 23°C to 90°C, the interior is made of 304-grade stainless steel for erosion and high-temperature resistance, while the exterior is coated steel for durability. The system and sub-systems are shielded against sand and dust intrusion. A turntable, externally controlled, rotates the test specimen, and a viewing window with wipers allows monitoring of the testing process. This robust design ensures reliable performance under harsh desert conditions.
