Refrigerant Compressed Air Dryer

Refrigerant dryers are the most common type of drier technology used by many industries. As the name suggests, heat exchangers are used to cool compressed air which will condense the bulk amount of water vapour within the air. Once the compressed air is cooled and water is removed, the air is reheated to around room temperature to ensure no more vapour forms within the pipe system. In the above image from left to right you can see the air compressor, air tank (to store the compressed air), the refrigerant air dryer and the condensate management on the far right to collect the water and oil removed from the compressed air.

CompAir refrigerant dryers are manufactured in-house at our Fogliano plant, Italy where they use the latest cutting edge technology to produce maximum energy efficiency in the drying process, in other words to use as little energy as possible to complete the air drying process. Our comprehensive dryer ranges offer a host of benefits to the user including:

  • High quality heat exchangers with low pressure losses
  • Energy saving mode – shuts dryer off during low loads
  • Full feature, multi-function innovative control panel
  • Anti freeze mode – shuts dryer off to avoid icing
  • Low operating costs
  • Compact design
  • Alarm display with history of alarms
  • Effective condensate separation
  • Easy to install, operate and maintain
  • Simplified access to unit for easy maintenance

Our refrigerant dryers deliver a comprehensive, cost-effective solution to multiple applications across a wide range of sectors including automotive, manufacturing, petrochemical, oil and gas, dry cleaning and light processing to name a few, many 1000's of CompAir compressed air dryers are in use today across the world. They offer an excellent return on investment, updating your compressed air equipment will offer a payback a lot quicker than you may think, since these dryers offer a step change on energy savings which can be made.

Why select a refrigerant over a desiccant dryer ?


This graphic shows the different dryer technology types and how much water extraction is possible from the compressed air, for each type. In a nutshell, desiccant dryers can extract more water per mthan refrigerant, but will use more energy in the process, fridge (refrigerant) dryers also require less maintenance in comparison to desiccant ones. CompAir's patented sub-freezing technology can remove more water than a standard refrigerant dryer and use less energy than a desiccant dryer. You can also see the different air quality classes achievable, class 0 being the purest, read more about air quality classes on this page.

The size of the dryer you need is also dependant on the air flow rate and the air quality class you need depends on the process the compressed air is serving, some processes require purer air than others. Please contact us directly to understand which option is best for your process.


Single Source Compressed Air Systems

Unwanted substances can and do occur in compressed air – from the ambient air inducted and generated by the process, e.g. dirt, dust, water, oil, and other micro-contaminants. By installing the correct air treatment system, with the correctly sized compressed air dryer for your application, moisture and contaminants that will damage your production and application efficiency and increase costs will be avoided altogether. In addition, air treatment enables the delivery of compressed air to the exact quality specified by the application or process.

Meeting or exceeding even the most stringent air purity standards by removing contaminants from compressed air with the correct filtration will undoubtedly lower operating costs significantly and extend the service life of your compressed air systems and application equipment.
