FILTER-DRIERS
Liquid Line Filter Drier
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.
A Manitowoc filter-drier 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.
Listed below are the recommended O.E.M. field
replacement driers:
Liquid Line Driers
Suction Line Filter Drier
The suction filter traps particulate only and does not
contain a desiccant. The filter needs replacement when:
1. The pressure drop across the drier exceeds 2 psig.
2. The total system refrigerant charge has escaped
and the refrigeration system has been exposed to
the atmosphere.
3. A compressor is replaced.
4. Refrigeration system contains contaminants.
