The low temperature cold trap can capture the steam and harmful gas discharged from the vacuum drying oven or vacuum concentration device, improve the efficiency of the vacuum system, greatly reduce the steam intake of the vacuum pump, and prolong the service life of the vacuum pump.

The temperature of low temperature cold trap adopts digital display mode, which is convenient to determine the start-up time of vacuum pump and prevent water in piping from being pumped into the pump.

The tank is made of 304 stainless steel, which can be used in water system and ethanol system experiment. After equipped with glass condenser, it can be used in acid system and organic solvent system experiment.

It can be used in the drying system of capacitor, battery pole piece and battery cell.

It can be used as pre freezing tank and low temperature tank.

Equipped with drain valve, easy to control the discharge of collected liquid.

Application principle:

There are some residual gases in the high vacuum environment using oil diffusion pump. More than 80% of them are water steam, oil steam and other high boiling point steam. However, the ability to remove the residual gas is low and the time is long. Moreover, the residual gas is the pollution source of the workpiece, which affects the production and quality of the products. Ultra low temperature trap pump is the best choice to solve the problem.

The working principle of ultra-low temperature trap pump: a refrigeration coil which can reach below - 120 ℃ is placed in the vacuum chamber or the pump port of oil diffusion pump. Through the low-temperature condensation effect on its surface, the residual gas in the vacuum system can be quickly captured. Therefore, the vacuum time can be greatly shortened (60-90% of the pumping time can be shortened), and a clean vacuum environment (the vacuum degree can be increased by half an order of magnitude, reaching 10-8 Torr, 10 ˉ 5pa)

It can be widely used in various industries, such as injection molding and suction molding in plastic industry. The water chiller can accurately control the temperature of plastic molding mold to shorten the molding cycle, accelerate the product finalization, so that the product does not deform and shrink, but also can improve the surface finish. It is also suitable for cooling CNC machine tools, coordinate boring machines, grinding machines, machining centers, modular machine tools and spindle lubrication of various precision machine tools The cooling of sliding and hydraulic transmission media can accurately control the oil temperature, effectively reduce the thermal deformation of the machine tool, and improve the machining accuracy of the machine tool; in addition, it is also suitable for electroplating industry, food industry, bleaching and dyeing industry and other industries.
