Answer: The drainage volume of the automatic drain is limited. If the amount of condensate generated by the cold dryer is greater than the drainage volume of the automatic drain at the same time, condensate will accumulate in the machine. Over time, the condensate will accumulate more and more. Therefore, in large and medium-sized cold dryers, more than two automatic drains are often installed to ensure that condensate does not accumulate in the machine. The automatic drain should be installed downstream of the precooler and evaporator. The most common method is to install it directly below the gas-water separator.
