Application Notes of Sand and Dust Test Chamber

Sanwood Technology's sand and dust test chamber is a professional reliability environment testing equipment, which can simulate the natural wind and sand climate, and help customers assess the durability of products in the wind and sand climate by simulating the weather of sandstorms.

Equipment features of sand and dust test chamber

The sand and dust test chamber of Sanwood Technology has the following features:

Moisture and heat system: Heating and dehumidifying evenly.

Operation device: fully automatic powder exchange device, easy to operate.

Circulation dust blowing system: the equipment adopts ‘O’ type closed vertical dust blowing circulation system, so that the airflow can flow smoothly, the dust disperses evenly and is not easy to agglomerate.

Temperature control system: There is an intelligent temperature controller to control the temperature, and the temperature can be directly displayed digitally.

Test Placement: No funnel design, easier to place the test samples, no need in pre-set pit.

High-quality materials: the outer wall is made of double-sided galvanized steel plate with plastic spraying surface treatment; the inner wall is made of SUS304 stainless steel plate to ensure the corrosion resistance and durability of the equipment.

Application of sand and dust test chamber

Sanwood's sand and dust test chamber is mainly used to simulate the destructiveness of the natural wind and sand climate on the product, to detect the sealing performance of the product shell, applicable to most of the machinery, electrical appliances, electronics, electrochemical and electromechanical products. By using Sanwood's sand and dust test chamber, it is possible to assess the resistance of these products when exposed to dry sand or dust-filled atmosphere, and whether they can operate normally.
