Environmental Test Chamber Sand Dust Test Chamber

Equipment Overview

The sand dust test box is named “Sand Dust Test Chamber”, which simulates the destructiveness of sandstorm weather in nature and is suitable for detecting the product's shell sealing performance. It is mainly used for the IP5X and IP6X grades specified in the enclosure protection grade standards. test. The equipment has a vertical circulation of dust-carrying airflow. The test dust can be recycled. The entire air duct is made of imported high-grade stainless steel plate. The bottom of the air duct is connected with the cone hopper interface. The inlet and outlet of the air blower is directly connected with the air duct and is in proper position. The diffuser at the top of the working chamber is connected to the working body to form an “O” closed vertical dust blowing circulation system, so that the airflow can flow smoothly and the dust can be dispersed evenly. Adopt a single high-power low-noise centrifugal fan, and use the frequency converter to adjust the wind speed according to the test needs.

Control System

1. With original German Molex programmable controller

2. Model EASY412-AC-RC, with time, and status display

3. The parameter setting is simple, no need to enter the program menu, you can directly enter the parameter menu to modify

4. The total test time can be controlled, the intermittent time of blowing dust, the period of blowing dust, and the intermittent time of the sample power supply.

5. The temperature adopts RKC, DC type temperature controller, which can be adjusted at RT+5°C~60°C to prevent the moisture in the test dust air from being wet and damp, and the humidity in the test chamber can be controlled below 50% R·H.

6. The test tank and the control cabinet are integrated, and the casters are installed at the lower part. Other systems are concealed, beautiful and easy to install.

7. Sample dust can be directly added into the tank. When the replacement is completed, the valve must be opened at the bottom of the tank funnel. The valve can be discharged in a short time, eliminating the need for manual refueling by operators.

Protective Device
1. Studio over-temperature protection
2. Heater short circuit protection
3. Vibration machine overload protection
4. Leakage protection
5. Safe and reliable grounding device

Main Features

1. Test chamber inner shell made of 3042B stainless steel
2. The shell of the test chamber is a high quality cold-rolled plate electrostatically sprayed
3. Blow dust motor is a special stainless steel shell, strong sealing, low noise, high wind speed
4. The inner shell of the box is funnel-shaped, and the vibration period is adjustable. The dust is flying freely and falls down next to the blowing hole.
5. There is observation window on the door, which can observe the status of the sample in the box when the dust blowing stops.
