Description
Package Design
At first glance, the ruggedness and ease of serviceability engineered into the CRN Series becomes apparent. Fabricated from solid steel, the corrosion resistant epoxy powder paint and the fit and finish of the cabinet, foretell of the quality to be found within. At the touch of a button, quick fasteners release each lift out door panel. Easy interior access and user-friendly serviceability translate to reduced maintenance costs.
Heat Transfer
CRN25 models incorporate heat exchangers crafted from multiple offset layers of press formed AISI 316 stainless steel. Press forming creates peaks and valleys that form media channels that are rich in fluid turbulence. This prevents fouling and maximizes energy efficiency.
Maximum Extraction Separator/Filter
Effective moisture removal at all flow rates is the key to preserve dew point stability. CRN25 driers include Grade B two-stage cold filtration to ensure maximum water extraction even under low flow conditions. Stage one mechanically entraps solids >10 microns with dual stainless steel orifice tubes. Stage two utilizes in-depth fiber media to coalesce water droplets and retain solid particles 3 microns and larger.
Get Connected
The extended inlet/outlet connections on CRN25 dryers were engineered with foresight to readily accept all CFF Series Filters without the need for cumbersome adaptors and fittings. You gain the installation flexibility you need today that may help you be prepared to meet the changes of tomorrow.
Refrigeration Process
CRN25 Series dryers enlist proven components and modern materials to deliver the durability you expect from Champion. Hot, moist incoming compressed air enters the Precooler/Reheater where it is precooled by the cold dehydrated airstream. Environmentally friendly low-pressure refrigerant gas is pressurized in the refrigeration compressor.
Once compressed into a high-pressure gas, it then flows through the condenser and changes to a cold 35°F liquid. The thermal expansion valve precisely meters the cold liquid refrigerant into the evaporator where the work is done. Hot, saturated compressed air enters the evaporator at the end opposite the incoming liquid refrigerant. The compressed air is chilled as they cross paths. Water is condensed out of the cold exiting air and is efficiently removed in the Separator/3 micron Filter.
The cold air stream then flows through the Cold Coalescing Oil Removal Filter (optional on the CRN25) where oil droplets and aerosols to 0.008 ppm w/w are captured and removed. The exiting cold, dry compressed air then reenters the Precooler/Reheater where it is reheated by the hot incoming air to prevent pipe sweating in your plant. Finally, the warm refrigerant is now a low-pressure gas and returns to the suction-side of the refrigeration compressor to continue the process.
