DEHYDRATOR DEW POINT READINGS
1. LP air (type I) dehydrator’s normal dew point
This reading is taken every 4 hours of dehydrator
service. Readings verify that the dehydrator is operating
correctly. The normal readings of the various types of
air dehydrators are as follows:
reading is a dew point temperature reading of 40°F or
lower at 80 lb/in2. This indicates that the dehydrator is
delivering an air quality within its design capability. A
reading of 50°F or higher at 80 lb/in2 indicates that the
dehydrator is not working properly, and you should
check the applicable technical manual.
