The A-4400 Series Refrigerated Air Dryers are designed for continuous operation to supply dry air to pneumatic control systems. All components are selected and assembled to provide dependable service over a long period of time with a minimum amount of maintenance. The air dryer uses R-134a refrigerant, an environmentally friendly HFC, minimizing the risks and/or costs associated with use and disposal of refrigerants.

Overview

Six variations of A-4400 Series Refrigerated Air Dryers are available with flow capacities of 12, 17, and 23 scfm (5.7, 8.0, and 10.9 L/s). Models can be ordered with an optional factory mounted Air Purification System consisting of a coalescing oil removal filter with integral pressure drop indicator, packed column type activated carbon oil vapor removal filter, service bypass valve, pressure reducing valve, safety relief valve, and power on/fail lamp. On models featuring an Air Purification System, a low pressure gauge is furnished on the reducing valve to provide output pressure indication. Refer to Table 1 for a comprehensive listing of refrigerated air dryers available. As outlined in Product Data A-4000 and the Installation and Service Manual for PureFlow Air Compressors (Publication No. 2629), clean, dry, oil-free air is essential to any pneumatic control system. Existence of water, oil, and/or particulate in air lines and instruments can cause instrument calibration to drift, often leading to equipment failure. For A-4400 Series Refrigerated Air Dryers not equipped with an optional factory mounted Air Purification System, a properly configured air supply system must include a coalescing oil removal filter as well as an activated carbon oil vapor removal filter. All A-4400 Series Refrigerated Air Dryers feature a hermetically sealed compressor, heat exchanger, and automatic condensate drain trap. An insulating sleeve, that easily slips on and off, covers the automatic condensate drain trap to eliminate external condensation. An evaporator pressure gauge and the automatic condensate drain trap with particle filter are internally mounted and are easily accessible through the end of the unit. All refrigerated air dryers also include a standard cord and plug for 115 volt 60 Hz, single-phase electrical service. Where permanent wiring is required, the cord is easily removed and conduit may be used.

Features

• Superior Part Load Performance
  
  Dew point remains steady as air consumption and cooling loads decrease, ensuring consistent water removal performance at all conditions including critical low-load operating points (without threat of unit freeze-up). Evaporator design eliminates the need for, and maintenance of, a hot gas bypass valve.
  
  
• Available with Optional Factory Mounted Air Purification System
  
  Particle filter (standard)/coalescing filter/activated carbon filter/service bypass valve/pressure reducing valve combination provides precise, clean, dry, oil-free air, enabling the control system to operate at peak performance.
  
  Full instrumentation including coalescing filter pressure drop indicator, refrigerant and air pressure gauges, and power on/fail lamp simplifies operation and maintenance with quick and easy visual identification of unit performance.
  
  Minimizes installation time via factory mounting and piping of all components, including service bypass valve.
• Available in Three Flow Capacity Sizes Utilizing One Universal Cabinet; UL Listed for US and Canada
  
  Allows application flexibility to minimize cost. Standardized design with common footprint.
  
  
• Uses R-134a Refrigerant
  
  Environmentally friendly HFC, minimizes risks/costs associated with use and disposal of refrigerants.
