Bio Gene Model No-BTI-SDC-422 The BioGene Sand and Dust Chamber is a cutting-edge environmental testing equipment designed to simulate harsh conditions of sand and dust exposure for various products and materials. This chamber is an essential tool for industries such as automotive, electronics, aerospace, and defense, where products must withstand extreme environments to ensure their reliability and durability.

Sand and dust chamber is used during device development, testing and evaluation to check reliability relative to atmospheric effects from dry sand and dust (fine sand).

This chamber is an essential tool for industries such as automotive, electronics, aerospace, and defense, where products must withstand extreme environments to ensure their reliability and durability.

Sand and Dust Chamber:
Air containing sand and dust is circulated in a wind tunnel, flowing from the top to the bottom of the test area.
The san and dust therefore form a laminar flow from above the test sample and are blown against it, so the test plan needs to specify the test sample placement direction.
The test area measures 4000 x 2000 x 2000 mm (W x H x D). The test sample surface area needs to be no more than 30 to 50% of the floor surface area to ensure there is a path for the air flow.



Constructed with CRCA sheet, Stainless Steel (304, 316 & 316 L) or Galvanized sheet. Interior chamber is made of stainless steel with mirror finish. The door is solid and lockable with a micro switch enabling an interlocking system. The door is provided with toughened glass observation window and a rubber wiper with rotating handle.


The Gap between the walls is filled with high-grade seams and fireproofs non-hygroscopic 2" thick Mineral wool insulation, which is impervious to corrosive vapors and fumes and also ensures maximum thermal efficiency in our sand and dust chamber.


Indirect heating system is provided in our units, comprising of air heaters made of high grade Kanthal A-1 wires of suitable wattage. The warm air is evenly distributed throughout the chamber through efficient motor fans ensuring very good temperature sensitivity.



The temperature inside our temperature and humidity control cabinets is controlled through programmable micro-processor based temperature controller cum indicator.




Temperature ranges of our standard models are 20°C to 80°C.  However we have the capacity to modify the same to suit the individual specialized requirements of our customers.



Bio Gene Equipment included an appropriate standard make stabilizer for better stability during incubation.
