 | Troubleshooting Fan Coil Evaporators, Part 1
The art and science of troubleshooting finned coil
evaporator performance varies as much as the applications in which this
refrigeration component is placed. To understand the performance of an
evaporator, you must first understand what you are dealing with. Evaporator
design, refrigerant feed and coil engineering all must be factored into
evaluating performance.

Ammonia Pump-Out Systems, Part 4
At one food processing plant, a
complete pump-out system was installed as part of the initial installation of
the ammonia refrigeration system. It consists of a bank of pump-out valves, an
oil regenerator, and a 50 hp pump-out compressor.

Ammonia Pump-Out Systems, Part 3
In Parts 1 and 2, I discussed the advantages and features of a pump-out
system. Now, I’ll demonstrate how those features can be put to use via
a case history at a representative frozen food plant located somewhere
in the United States.

Ammonia Pump-Out Systems, Part 2
In Part 1, I discussed the advantages of a pump-out system, which include enabling safer operation of the ammonia refrigeration system and providing zero emissions during plant tie-ins. In this column, I’ll look at some typical features of a pump-out system
