Designed to meet and exceed the specifications set by the MIL-STD-810F by a factor of 100 in order to simulate desert environments for the testing of equipment and devices. The Desert Wind™ sand/dust test chamber is ideal for those striving to meet MIL-STD-810F standards in the testing and certification of a manufactured device or laboratories that require certification of a device.
Desert Wind Environmental Test Chamber Capabilities
- Automated Temperature Control from 70oF to 200oF
- Automated Humidity Control for dust tests to less than 30% RH
- Automated Wind Velocity Control from 0-29 meters per second
- Automated Industrial Hygiene System protects the operator from silica exposure.
- Automated Dust recirculation process
- Automated Sand disposal process
- Automated Sand or Dust Concentration System provides a calibrated loss-in-weight measurement using: Rate = (Concentration)(Area)(Velocity)
This concentration system is unique to the Desert Wind™ Patented design. It is the only system currently capable of providing a repeatable concentration of sand or dust to the test chamber.
DESERT WIND ENVIRONMENTAL TEST CHAMBERS
Part One: The Desert Wind (TM) Blowing Sand & Dust Test Chamber is being prepared to test a specimen in accordance with MIL-STD-810G Method 510.4. The blowing dust test chamber exceeds the MIL-STD concentration standard by at least 92%. The system is fully automated using the latest Allen-Bradley PLC controls and software.
Part Two: The Desert Wind (TM) Blowing Dust and Sand Environmental Test Chambers incorporate a rotating table. The feature allows remote positioning of the test specimen from the local operator console or via a remote operator console. Here, the specimen is verified to rotate freely.
Part Three: Handling silica dust is serious business. Here, the blowing dust environmental simulator system is loaded or charged with silica dust using the built-in, automated system. This makes the process of handling silica safer and less labor intensive. The automated system is designed to comply with OSHA requirements for Industrial Ventilation as required by the American Conference of Industrial Hygienists and Part 21 of the Code of Federal Regulations.
Part Four: Today’s laboratory environment requires automation in order to perform complex blowing dust and blowing sand testing. Yesterday’s hand written checklists no longer measure up to the world of technologically advanced environmental simulators such as the Desert Wind system. The fully automated test chamber produces 8640 data points in a typical 6 hour blowing dust test. In this video the test is started with a few operator inputs at the local touch screen or remotely via Ethernet.
