Compressed Air Dryer

Compressed Air Dryer is a device meant for removing water vapor and various contaminants or impurities from the compressed air. The common types of compressed air dryers in use nowadays include regenerative desiccant dryers, refrigerated dryers, deliquescent dryers, and membrane dryers. Each of these dryers has its own unique and specified function to perform, and they are used in diverse applications according to the need and suitability. But, the main objective of each of these dryers is almost the same, i.e., to prevent condensation and moisture by removing vapor from the air, so that the sensitive industrial processes can be carried out smoothly and uninterruptedly. These dryers also solve the problem of tool corrosion.

Specifications of Compressed Air Dryers

While choosing a compressed air dryer, the following specifications should be taken into consideration:

Drying Capacity: It is the maximum volume of air that a dryer can dry at a time. The ideal capacity is 100 psig.
Maximum Pressure: It refers to the maximum rated inlet pressure of the dryer.
Dew-point: It is the measurement of the amount of water vapor present in the air. It is preferable to choose a dew-point temperature just below the lowest surrounding temperature around your compressed air system.
Motor Power: Motor power or motor horsepower is a reference value associated with the size of the dryer. It totally depends upon your requirement and the ambient operating temperature.

Compressed Air Dryer mainly consists of :

Pressure Gauge - These monitor pressure

• Integral Filters - These undergoes mechanical trapping of moisture, oil, smoke, etc.
  
  
• Automatic Condensate Drain - It senses the level of removed moisture and automatically drains it off.

Characteristics of Compresses Air Dryer

• Pre-cooler uses helical fin copper pipe to reduce heat load.
  
  
• Direct-vaporized heat exchanger immediately responds to change of load.
  
  
• During separation of liquid, the highly efficient moisture separator will separate the oil and dirt from the compressed air.
  
  
• Excellent filtration effect: technical index is 3µ5ppm.
  
  
• Auto drain has 3 levels which are each safe and reliable.
  
  
• Multiple control methods: instrument, computer, PLC control, etc.
  
  
• Compressor system-controlled with safety protection.
  
  
• Temperature controller gives stable dew point.
  
  
• Various alarm signals and protection devices.
  
  
• Two water cooling methods: air or water-cooled.
