Compressed Air Dryer System

Refrigerated Air Dryers

A refrigerated air dryer works to dry compressed air by cooling down the warm air that enters the dryer. Once cooled, the water vapour condenses into water. At Cleveland Compressed Air Services, you'll find a wide range of refrigerated dryers to suit your business needs.

Refrigerated Air Dryers

Frequently Asked Questions

A compressed air dryer is a machine built to significantly reduce or remove moisture and water vapour that is inherently present in compressed air. Water vapour needs to be reduced or eliminated as once the moisture in the compressed air reaches the dew point (under the right conditions), it can condense into a harmful fluid.

The effects of liquid or water on the parts of refrigerated compressed air dryers can be corrosive, damaging and expensive. If the condensate is left to accumulate inside the compressor unit, it could slowly dry into the metal surfaces of the different moisture-sensitive motor components, leading to rusting. In turn, the compressor could start to drag, malfunction and eventually overheat due to corrosion.

This is why compressed air dryers are used with air compressors. Doing so prevents condensation that could affect your machines, tools, piping and product quality and creates a safer workplace for your employees.

There are different types of compressed air dryers, and they also operate in different ways. Refrigerated compressed air dryers, desiccant air dryers, membrane air dryers, speciality gas and liquid dryers, and deliquescent air dryers are the standard forms of air dryers used with air compressor systems.

Your specific application or industry will determine which type of compressed air dryer you should use. In turn, the kind of dryer you use will determine how the machine works and the air quality it produces.

Industries that utilise compressed air dryers include the naval, chemical and petrochemical, nuclear power, pharmaceutical, manufacturing, and food and beverage sectors. However, since there are specific types of air dryers, they also vary significantly in terms of their industrial applications.

The refrigerated air dryer is one of the most common air dryers used with compressed air systems. In fact, refrigerated dryers are the most popular air dryers you’ll find being used with industrial compressed air systems. One reason for this is that refrigerated air dryers are reasonably priced. They are also compatible with setups that are not operating under extremely hot conditions and where there is no requirement for exceptionally high drying capacity.

A refrigerated compressed air dryer uses a simple mechanism comprising a single or several heat exchangers that work to cool the hot compressed air. The heat exchangers condense out most of the warm wet air from the compressed air and remove it using a separator equipped with an automatic drain.

To get the right refrigerated air dryer that would provide you more years of use, make sure you consider the following:

  • Check the pressure dew point (PDP) you need for your air compressor system. You can get PDP information from the manufacturer, or you can make the calculations yourself.
  • Determine the dew point class of the refrigerated air dryer you require. Note that these classifications are based on the industry standards that apply to compressed air dryers, and remember that the lower the dew point, the dryer the air.
  • Ascertain the right dryer size and the refrigerant circuit you need for your industrial or commercial setup.
  • If you're operating in a cold climate, a hot gas bypass valve can keep your refrigerated compressed air dryer running at the optimal temperature without risking the health of your system.

In general, businesses or industries that use compressed air systems can benefit from using a refrigerated air dryer.

Some industries that utilise refrigerated air dryers include healthcare, pharmaceuticals, chemical manufacturing, and food and beverage. Refrigerated air dryers are particularly commonly used in beverage carton processing and for transferring chemicals in sterile environments.

However, there are other types of compressed air dryers, so it’s crucial to know the needs of your business to determine whether refrigerated air dryers will be the solution to your compressed air needs.

Refrigerated air dryers are suitable for various industrial applications where moisture reduction or elimination is required. Aside from this, they offer other benefits:

  • They are considered an economical choice because of their low acquisition cost.
  • They prevent moisture-related corrosion and oxidation in woodworking and other applications.
  • They are very reliable, simple to operate and require very little maintenance.
  • They can extend the life of your air compressor system significantly.
  • They are energy-efficient, so you can save on power bills.


Pressure dew point is the temperature at which water vapour in the air becomes saturated with water and condenses to form liquid dew. The higher the dew point, the more moisture there is in the air. It is a common measurement to assess how much moisture will be present in an environment over time.

Cleveland Compressed Air Services has been around since 1994. We’ve been part of Australia’s commercial and industrial landscape, providing compressed air solutions to a wide range of industries and businesses.

We not only offer a comprehensive selection of refrigerated compressed air dryers and components but also supply air blowers and industrial chillers. Moreover, our highly experienced team of professional technicians have the familiarity and capabilities to handle all your repair, maintenance and other servicing needs.

Flow rate is the amount of fluid that passes through a given point at a specific time. Technically, it's the volumetric airflow rate, which means how much volume flows past a point per unit time. This can be measured in cubic feet per minute (CFM). The more CFMs, the more air your unit will disperse throughout your space.
