Cold Trap
In vacuum applications,a cold trap is a device that condenses all vapors(except the permanent gases) into a liquid or solid. The main purpose is to prevent vapors being produced by an experiment from entering the vacuum pump where they would condense and contaminate it. Clod traps can also cool surfaces or baffles to prevent oil vapors flowing from a pump into a chamber. In such a case,a baffle or section of pipe containing a number of cooled vanes, will be attached to the inlet of an existing pumping system.
Cold Trap
Features
Improve pump working efficiency
The low temperature of the cold trap can condense the water vapor directly in the cold trap, thus greatly improving the working efficiency of the vacuum pump.
Protect vacuum pump
Pumps that use oil either as their working fluid (diffusion pumps), or as their lubricant (mechanical rotary pumps), are often the sources of contamination in vacuum systems. Placing a cold trap at the mouth of such a pump greatly lowers the risk that oil vapors will back stream into the cavity.
