Compressor system having a refrigerated dryer

An apparatus comprising:

• a compressor structured to compress a working fluid to produce a flow of compressed gas;
• a main discharge conduit from the compressor which is structured to convey the flow of compressed gas;
• a splitter at the main discharge conduit structured to receive the flow of compressed gas, the splitter coupled with an offtake passage and a main passage, the offtake passage structured to flow an offtake flow of compressed gas which includes a portion of the flow of compressed gas flowing into the splitter, the main passage structured to flow a main flow of compressed gas which includes the remainder of the flow of compressed gas that is not flowed to the offtake passage;
• a refrigerated dryer having a refrigeration fluid circulating between an evaporator and a condenser, the evaporator structured to flow relatively cool refrigeration fluid, the evaporator in thermal communication with and useful to remove moisture from the main flow of compressed gas, the condenser structured to receive relatively warm refrigeration fluid from a refrigerant compressor after it has flowed from the evaporator, wherein the condenser includes a conduit having an internal passage for the conveyance of the refrigeration fluid and an array of external cooling fins in thermal communication with the conduit that conveys the refrigeration fluid such that the external cooling fins assist in cooling the relatively warm refrigeration fluid received from the refrigerant compressor;
• a fan structured to provide motive force to a cooling fluid across the external cooling fins of the condenser;
• and
• a plurality of air jet nozzles having an outlet oriented to discharge the offtake flow to the external cooling fins to aid in removal of foreign debris that reduces the heat transfer effectiveness of the external cooling fins;
• wherein the compressor and offtake passage are sized to provide the offtake flow of compressed gas at an offtake pressure and an offtake flow rate;
• and
• wherein the offtake pressure and the offtake flow rate of the offtake flow of compressed gas causes the offtake flow discharged from the plurality of air jet nozzles to be at a higher momentum flow than the momentum flow from the fan during operation.
