Benefits of the Integrated Refrigerated Dryer
Atmospheric air naturally contains water vapor. Compressing the air concentrates that moisture, which can condense into liquid water as the air cools inside the receiver tank and distribution piping.
The integrated refrigerated dryer helps reduce moisture in the compressed-air system and provides several potential benefits:
- Helps protect pneumatic tools from internal corrosion
- Reduces water accumulation in compressed-air piping
- Helps protect CNC machinery and automation components
- Improves air quality for paint and finishing applications
- Reduces moisture-related equipment maintenance
- Helps prevent water contamination at points of use
- Simplifies installation compared with a separate dryer
- Reduces external piping and electrical connections
- Helps protect downstream regulators and control valves
- Supports more consistent production-air quality
The refrigerated dryer must be properly ventilated, drained, and maintained to provide dependable moisture removal.
Benefits of the 132-Gallon Receiver Tank
The integrated 132-gallon receiver provides stored compressed air that helps the system respond to short periods of increased demand.
Potential benefits include:
- Stabilizes compressed-air system pressure
- Provides stored air for intermittent demand
- Helps reduce rapid compressor loading and unloading
- Supports short bursts of high air consumption
- Encourages condensate separation as compressed air cools
- Reduces pressure fluctuations at downstream equipment
- Simplifies installation compared with a separate receiver tank
- Reduces external piping requirements
The receiver tank does not increase the compressor’s continuous airflow capacity. Sustained air consumption must remain within the compressor’s rated output of 82.2 ACFM at 125 PSIG.
Additional Air Treatment Recommendations
Although this compressor includes a refrigerated dryer, additional air treatment may still be required to remove condensed moisture, particulate contamination, and oil aerosols.
Depending on the application, the compressed-air system may also require:
- Moisture separator
- Automatic receiver-tank drain
- Automatic dryer condensate drain
- General-purpose particulate filter
- High-efficiency coalescing filter
- Activated-carbon filter
- Pressure regulator
- Oil-water separator
- Point-of-use filtration
Paint spraying, instrumentation, sensitive CNC machinery, and other critical processes may require additional filtration or a lower pressure dew point than a standard refrigerated dryer can provide.
Installation Considerations
The compressor should be installed indoors on a level, structurally adequate surface with sufficient room for ventilation, inspection, and routine maintenance.
Before installation:
- Confirm that the facility has 208, 230, or 460-volt three-phase electrical service.
- Verify that total compressed-air demand is within the compressor’s 82.2 ACFM capacity.
- Confirm that piping and downstream equipment are rated for the operating pressure.
- Verify the electrical requirements shown on the refrigerated dryer data plate.
- Provide adequate ventilation around both the compressor and dryer.
- Prevent heated cooling air from recirculating into either cooling intake.
- Keep the package pre-filter and fresh-air intake clear of obstructions.
- Install the required electrical disconnects and overcurrent protection.
- Confirm that the electrical system can support the Wye-Delta starter.
- Use properly sized compressed-air piping.
- Install a flexible connection between the compressor and rigid piping.
- Verify that the dryer and receiver condensate drains are installed and operating correctly.
- Route oily condensate to an approved oil-water separator or disposal system.
- Maintain the manufacturer’s recommended service clearances.
- Verify proper motor rotation during startup.
- Configure the ES4000 Connect controller for the application.
- Activate ICONS remote monitoring when desired.
Although the QRS 20-30 platform is designed for ambient temperatures up to approximately 115°F, cooler and well-ventilated installation conditions generally support better reliability and longer equipment life.
Electrical and mechanical installation should be completed according to Chicago Pneumatic’s instructions and all applicable local codes.
