Air Treatment Systems 0

The flexibility engineered into every RNC Series dryer allows you to satisfy your air quality requirements with a single package. Enlist us to deliver the dew point stability, air quality, energy efficiency, and product reliability that you expect from Gardner Denver. ISO 8573.1 Air Quality Classes 1992 earmarked the year the International Organization for Standardization (ISO) established ISO 8573.1 as the global benchmark for evaluating the quality of compressed air. Thus, providing engineers with a universally accepted unit of measure for quantifying compressed air stream contaminants. Namely Solid Particulates, Moisture, and Oil.

Built To Perform 0

Package Design At first glance, the ruggedness and ease of serviceability engineered into RNC 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. Proven Performance All models use reliable refrigeration compressors and environmentally friendly refrigerants. Models through RNC750 use proven reciprocating refrigeration compressors and R-134a refrigerant. RNC1000 through RNC3000 incorporate rugged scroll compressors and R-404a refrigerant. You benefit from long component life, and exceptional around-the-clock performance. Heat Transfer RNC 10–15 models have the patented static condenser technology that eliminates the need for a cooling fan. These models include an on/off switch, longer power cord (8 ft), a timer operated drain valve with isolation valve on RNC, a float trap on RNC, and deliver heated outlet air to eliminate sweaty piping. RNC models 25–75 benefit from our smooth handcrafted all copper heat exchangers. Only large bore multiple tubes-in-tube designs efficiently split the airflow to achieve the low pressure drop, high heat transfer. RNC Series models 100–3000 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. RNC25 and larger includes 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 RNC dryers (RNC25–RNC750) were engineered with foresight to readily accept all FIL Series Filters without the need for cumbersome adaptors and fittings. RNC/1000 - 3000 inlet/outlet connections are on top of unit for ease of installation. You gain the installation flexibility you need today that may help you be prepared to meet the changes of tomorrow.

Refrigeration Circuit 0

RNC Series dryers enlist proven components and modern materials to deliver the durability you expect from Gardner Denver. Hot, moist incoming compressed air enters the Precooler/Reheater (1) where it is precooled by the cold dehydrated airstream. Environmentally friendly low-pressure refrigerant gas is pressurized in the refrigeration compressor (2) Once compressed into a high-pressure gas, it then flows through the condenser (3) and changes to a cold 35°F liquid. The thermal expansion valve (4) precisely meters the cold liquid refrigerant into the evaporator (5) 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 (6). The cold air stream then flows through (7) the Cold Coalescing Oil Removal Filter (optional on models RNC25–RNC3000) 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 (1) 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 (8) of the refrigeration compressor to continue the process. RNC 10–15 Warm saturated air enters the Evaporator (A), where it is cooled by an air-to-refrigerant process. Water vapor condenses into a liquid for 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 to ambient. This eliminates the need for a cooling fan and prevents pipeline sweating at the air outlet. A Constant Pressure (F) Expansion Valve (CPEV) modulates the flow of liquid refrigeration to the Evaporator (A). This eliminates freeze-ups and assures continuous, automatic dew point control. The CPEV responds to pressure changes as the refrigerant leaves the Evaporator. This maintains the proper cooling rate under all load conditions. The CPEV is adjusted at the factory to deliver automatic operation.
