The liquid nitrogen cryogenic low temperature test chamber is mainly composed of liquid nitrogen storage tank, pressure regulating protection device, electric control cabinet, deep freezer, heat exchanger, heat preservation device, electric motor, circulation fan and temperature regulating device. The liquid nitrogen cryogenic low temperature test chamber uses liquid nitrogen as a cold source. The liquid nitrogen is stored in the cryogenic liquid storage tank. When using, the venting valve of the storage tank is closed first, and then the pressure increasing valve is opened. The internal pressure of the storage tank is increased due to the partial nitrogen gasification. At this time, the liquid nitrogen outlet valve is found. That is, it is pressed out from the storage tank and enters the deep freezer through the pneumatic diaphragm regulating valve. After the liquid nitrogen enters the deep freezer, it is ejected through the nozzle. Since the temperature of the tank is higher than the temperature of the liquid nitrogen, it quickly vaporizes, and the volume expands, causing the temperature to drop. The axial fan blows the low-temperature nitrogen into the working chamber. The workpiece is cooled. Sensor Trash Bin With Ozone Sanitizing Sensor Trash Bin with ozone sanitizing is multifuctional. Multifunctional sensor trash can is not only with sensor function to help you much more effortless to trash and equipped with an ozone generator on the lid to release the ozone to do sanitize inside the bucket. The rubbish bin with ozone sanitizer could be open the lid automatically by waving your hands in its sensor area 15-25cm or kicking the bin body. The sanitizable garbage bin for home is designed with two buttons on the sensor screen. One is for lid stay open --press "open" the lid will open and it won't close until you press "close". The other is ozone switch--press the button, then the ozone generator will start release ozone to do sanitize inside the bucket.
