ELEMENT REPLACEMENT
PERFORMANCE
MD-R Series dryer’s performance varies according
to dryer lengths and flow rates.
Field replacement of MD dryer elements
longer than 48” is difficult without special
equipment and is not recommended. The
instructions below are for the 12”, 24” and 48”
length models
1. Hold the dryer end fitting assembly
behind the rotating purge fitting carrier.
2. Grip the end nut and rotate counter-
clockwise to remove. Repeat for the
opposite end.
3. Gently pull the Nafion
®
tube element out
of the housing just far enough to be able
to remove the rubber ferrule. Remove the
rubber ferrule.
4. Remove the element by pulling the
element out from the other end of the
dryer housing.
5. When installing the new element, handle
the membrane tubing with gloves to
prevent contaminating the tubing surface.
6. Once the element is positioned with equal
lengths protruding from each fitting, install
the rubber ferrules about ¼” from the end.
7. Install the end nuts and tighten as much
as possible by hand.
