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 capability.
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.
Listed below are the recommended O.E.M. field
replacement driers:
