Description

The importance of clean, dry compressed air
A well-designed air treatment system has several critical stages, each of which contributes to the goal of achieving dry, clean air. The diagram below represents a sample of a complete system from start to finish. The Digi-pro controller offers one-touch settings with digital dew point monitoring, energy-saving mode,
maintenance intervals, hour meter and status reporting.
The ESD3 controller offers savings features and alarm capabilities.
Aluminum Plate Heat Exchanger
With a state-of-the-art design, this component is standard for all units and offers some of the best savings in the industry
Very low pressure drop saves compressor energy
Thin aluminum plate thickness
High heat transfer surface area
Thick outer cylindrical walls offer increased strength
Optimized water separator for improved performance
Fast start-up and reaction times
Provides longer production time
Energy efficient
High-efficiency R134a refrigerant standards on all models
Best-in-class refrigerant compressors
Consume less energy than the competition
Displacement compressors (energy efficient and liquid shock resistant) are standard for models RFA-275 to RFA-7300
Pressure switches
Control condenser fan motor to save energy and system operation under desired conditions
Simple and safe electrical wiring
There are very few electrical wires inside the refrigerant side of the dryer. The electrical box has an external cover with outside access, so there is no need to open the dryer panels to gain access to the electrical panel
Dew point of 37F to + 50F depending on operating conditions
Sullair Warranty: 2 Years
Electrical Standards Compliance: UL-508A
Compact design n Suitable for small installation spaces n Two filters integrated into the dryer, saving duct costs, space, and labor time for technicians and end users n Flexibility and economy during transport n Easy accessibility n Easily accessible cooling components through screwless panels and plastic handles
