Product description
Parameters
-95°C/-135°C pot type cold trap is a small ultra-low temperature freezing equipment suitable for nano-waterproofing of electronic components, Parylene vacuum coating cold trap, biochemical petroleum experiment, cryogenic liquid bath, gas trapping, lyophilization And many other uses. The size and cooling method of the cold trap can be customized according to the needs of the user.
 
The important role of cold traps in vacuum operation
 
1, improve vacuum efficiency
The oil and gas and water vapor in the vacuum chamber are condensed into liquid by the low temperature of the cold trap, reducing the influence on the degree of vacuum. Freeze vacuum drying is a common drying method. Taking 1 g of ice as an example, it can produce 10,000 L of water vapor at 0.1 Torr. The moisture in the drying oven will produce a huge amount of water vapor. If these water vapors are only removed by a vacuum pump, the working efficiency of the vacuum pump will be extremely low. The low temperature of the cold trap can directly condense water vapor in the cold trap, which greatly improves the working efficiency of the vacuum pump. This is the reason for the low temperature drying oven, which is equipped with a cold trap.
 
2, reduce the impact of corrosive test gas vacuum pump
In vacuum systems, there are often corrosive agents present. Corrosive reagents are converted into gas molecules during the vacuuming process and are discharged into the atmosphere through a vacuum pump through a pipeline. Corrosive gases can cause permanent damage to the vacuum pump as it flows through the vacuum pump. For example, acid gases can corrode metal parts of the vacuum pump. Corrosive gases pass through the exhaust port of the vacuum pump and can also pollute the air if discharged directly into the atmosphere.
 
The use of a cold trap allows the corrosive gas to be collected by effective condensation before entering the vacuum pump, reducing the damage of the corrosive gas to the vacuum pump.
 
1. The freezer adopts non-azeotropic refrigerant mixture, single compressor natural cascade refrigeration cycle technology (taking into account the reliability of equipment and energy saving and mute); refrigerant is fluorine-free environmentally friendly products, compressor, refrigeration parts, electronic control system All of them are imported famous brands and are durable.
 
2. The freezer can be used only by connecting the power supply (220V~380V-50HZ), no need for other peripheral equipment, no wearing parts and consumables, safe and reliable, and low cost.
