Refrigeration Circuit

CRN 25–3000 Series dryers enlist proven components andmodern materials to deliver the durability you expect fromChampion. Hot, moist incoming compressed air enters thePrecooler/Reheater (1) where it is precooled by the colddehydrated airstream. Environmentally friendly low-pressurerefrigerant gas is pressurized in the refrigeration compressor (2)Once compressed into a high-pressure gas, it then flows throughthe condenser (3) and changes to a cold 35°F liquid. The thermalexpansion valve (4) precisely meters the cold liquid refrigerant intothe evaporator (5) where the work is done. Hot, saturatedcompressed air enters the evaporator at the end opposite theincoming liquid refrigerant. The compressed air is chilled as theycross paths. Water is condensed out of the cold exiting air and isefficiently removed in the Separator/3 micron Filter (6). The coldair stream then flows through (7) the Cold Coalescing Oil RemovalFilter (optional on models CRN25-CRN3000) where oil droplets andaerosols to 0.008 ppm w/w are captured and removed. The exitingcold, dry compressed air then reenters the Precooler/Reheater (1)where it is reheated by the hot incoming air to prevent pipesweating in your plant. Finally, the warm refrigerant is now a low-pressure gas and returns to the suction-side (8) of the refrigerationcompressor to continue the process.

SURE-SAVE cooling injection (optional on models CRN125 – CRN750only) protects the refrigeration compressor during extreme heatevents. When high-inlet air temperatures (up to 140°F) threatenthe refrigeration compressor, SURE-SAVE (9) injects cooling reliefinto the suction-side (8) of the refrigeration circuit. This lowersthe return gas temperature to compensate for the higher inlet airtemperature and sustains operation.

CRN 10–15

Warm saturated air enters the Evaporator (A), where it is cooled byan air-to-refrigerant process. Water vapor condenses into a liquidfor removal at the moisture separator (B) by an Automatic Drain(C). The cold, dry air is reheated as it passes through the Reheater(D) while the patented Static Condenser (E) radiates waste heat toambient. This eliminates the need for a cooling fan and preventspipeline sweating at the air outlet.

A Constant Pressure (F) Expansion Valve (CPEV) modulates the flowof liquid refrigeration to the Evaporator (A). This eliminates freeze-ups and assures continuous, automatic dew point control. The CPEVresponds to pressure changes as the refrigerant leaves theEvaporator. This maintains the proper cooling rate under all loadconditions. The CPEV is adjusted at the factory to deliver automaticoperation.

Fabricated fromsolid steel, the corrosion resistant epoxy powder paint and thefit and finish of the cabinet, foretell of the quality to befound within. At the touch of a button, quick fastenersrelease each lift out door panel. Easy interior access anduser-friendly serviceability translate to reduced maintenancecosts.

PROVEN PERFORMANCEAll models use reliable refrigeration compressors andenvironmentally friendly refrigerants. Models through CRN750use proven reciprocating refrigeration compressors and R-134arefrigerant. CRN1000 through CRN3000 incorporate ruggedscroll compressors and R-404a refrigerant. You benefit fromlong component life, and exceptional around-the-clockperformance.

HEAT TRANSFERCRN Series models 25-3000 incorporate heat exchangerscrafted from multiple offset layers of press formed AISI 316stainless steel. Press forming creates peaks and valleys thatform media channels that are rich in fluid turbulence. Thisprevents fouling and maximizes energy efficiency.

MAXIMUM EXTRACTION SEPARATOR/ FILTEREffective moisture removal at all flow rates is the key topreserve dew point stability. CRN25 and larger includes GradeB two-stage cold filtration to ensure maximum waterextraction even under low flow conditions. Stage onemechanically entraps solids >10 microns with dual stainlesssteel orifice tubes. Stage two utilizes in-depth fiber media tocoalesce water droplets and retain solid particles 3 micronsand larger.

GET CONNECTEDThe extended inlet/outlet connections on CRN dryers (CRN25-CRN750) were engineered with foresight to readily accept allCFF Series Filters without the need for cumbersome adaptorsand fittings. You gain the installation flexibility you needtoday that may help you be prepared to meet the changes oftomorrow.

CRN 10-15The patented static condenser technology eliminates the needfor a cooling fan. These models include an on/off switch,longer power cord (8 ft), a timer operated drain valve withisolation valve on CRN15 ,a float trap on CRN10, and deliverheated outlet air to eliminate sweaty piping.

* Lifetime Heat Exchanger warranty requires an CFF Series prefilter on theinitial purchase and annual filter element replacement with a genuine CFFSeries element. Standard warranty is 5 years on Heat Exchangers.
