Dedicated Purge Tank
The best location for dedicated purge tanks is above the air dryer

Check to be sure that the compressor discharge line is long enough to allow the compressed air temperature to drop below 175°F before it reaches the air dryer.
Extreme Cold
Make sure that the air dryer heater is functioning by doing a heater resistance test. (See the Maintenance Manual link above)
Check the line from the governor to the air dryer to be sure that its free of oil and water.
