FILTER-DRIERS
The filter-driers used on Manitowoc ice machines are
manufactured to Manitowoc specifications.
The difference between Manitowoc driers and off-
the-shelf driers is in filtration. Manitowoc driers have
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
which takes place during every harvest cycle.
These filter-driers have 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.
