DESERT WIND™ Stationary Test Chamber

OVERVIEW

 

Designed to meet the specifications set by the MIL-STD-810G 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-810G standards in the testing and certification of a manufactured device or laboratories that require certification of a device. 

KEY FEATURES:

  • Automated Temperature Control from 70°F to 200°F

  • 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.

BACKGROUND

 

The United States Military and Commercial Manufacturers have been seeking the capability to simulate the conditions or environment found in the Desert. Conflict in desert areas require people and support equipment to operate in the harsh environment. The demands of the harsh environment require specialized equipment to simulate the deleterious effects of operating and storing equipment in the deserts of the world.

Until now, there has not been an environmental simulator that can provide real-time recorded outputs of each critical parameter of a blowing sand or blowing dust environmental simulator. The shortfalls are typically in the area of particle concentration, particle velocity, particle distribution and air velocity at the test chamber cross-sectional opening. Current equipment offered that comprises a closed loop with particulate circulating through the air mover yields itself to non-repeatability. This means the dust or sand concentration and particle distribution into the test chamber is continuously variable.

This shortfall in design points to the disclaimer in the FOREWORD section of the MIL-STD-810G document. “Therefore users should not assume that a system or component that passes laboratory tests of this standard also would pass field/fleet verification trials.” Of course this is true, if we lack quantification, then our test results are not predictable or repeatable. In essence, we run a different test each time.

The Desert Wind™ stationary blowing sand and dust chamber can provide real-time data of each key test parameter while conducting the blowing test.  We offer consistent, repeatable testing for MIL-STD-810G, Method 510.4 that moves us towards predictive failure testing and analysis.

Stationary Chamber

The Desert Wind™ in its original application is designed to meet MIL-STD-810G, as well as perform to any desired parameters by the client. 

Each system can be designed to blow either sand or dust, at any concentration, at any velocity requested. Each system ensures consistent, repeatable, and automated testing making sure you get the best results possible.

 

VIDEO INFORMATION

PART 1 | The Desert Wind™ 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 2 | The Desert Wind™ 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 3 | 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 4 | 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.
