Filter-Driers
The filter-driers used on Manitowoc ice machines are
manufactured to Manitowoc specifications.
The difference between a Manitowoc drier and an off-
the-shelf drier is in filtration. A Manitowoc drier has
dirt-retaining filtration, with fiberglass filters on both the
inlet and outlet ends. This is very important because
ice machines have a back-flushing action that takes
place during every harvest cycle.
A Manitowoc filter-drier has a very high moisture
removal capability and a good acid removal capacity.
The size of the filter-drier is important. The refrigerant
charge is critical. Using an improperly sized filter-drier
will cause the ice machine to be improperly charged
with refrigerant.
