Cleveland Controls offers the Inline Bleed Hole Kit to deal with
situations where inline condensation is determined to be a problem
after the switch is installed and the process is running. The Inline
Bleed Hole Kit adds a 0.016” bleed hole feature to an existing installed
sensing switch. The bleed hole draws fresh air into the sample line,
helping to prevent the buildup of condensate inside the air switch
and sample line.
