Why You Need a Refrigerated Compressed Air Dryer

If you operate in an industry or manufacturing business that incorporates compressed air systems into daily operations, you’ve likely run into an issue stemming from water build-up.

The way that water gets into your compressed air system is through humidity in the air entering through the compressors inlet air filter. This water vapour then converts to liquid water inside your compressor, which could cause severe operational problems. A higher environment humidity, the larger quantity of water build-up you’ll find in your air compressor.

One of the most efficient ways to prevent this liquid water build up is to connect a refrigerated compressed air dryer to your current system.


How Does a Refrigerated Compressed Air Dryer Work?

A refrigerated air dryer is connected to your air compressor and cools the air to a specific temperature, usually between 2°C to 10°C. This is known as the dew point, the temperature at which the vapour will begin to condense into liquid water, in the given conditions.

This process of cooling will then drain away the liquid water within the air dryer system, preventing it from reaching the air compressor’s main chamber.


Benefits of Connecting an Air Dryer to Your Compressed Air System

If your industry or manufacturing business uses a compressed air system, then you need a refrigerated compressed air dryer. Here’s why:

Removes Impurities from Compressors

While drawing air, your compressed air system will be exposed to a range of impurities which may compromise its performance and cause damage internally. The impurities can also result in a build-up of mildew and mould which is not only harmful to the machine, but also the people operating it. These impurities include the following:

  • Moisture (water vapour)
  • Liquid water
  • Airborne pollutants (dust, pollen, etc.)
  • Oil

Refrigerated compressed air dryers will reduce the opportunity for these impurities to reach your air compressor, stopping them beforehand and filtering them out. This will help to reduce and prevent the build-up of mould, rust and corrosion in your compressed air system.

Assists in Prevention of Operational Problems

Excess liquid water and water vapour can cause operational problems if it reaches your air compressor. This could cause unexpected machinery downtime and long-term operational issues that are costly to rectify.

These problems could extend further, being transferred to any machinery or appliances attached to the air compressor – such as air tools used in production lines. The water and vapour could also be transferred and cause problems during application, affecting the end product.

Connecting a compressed air dryer to your compressor system will ensure the output of air is always vapour free. This reduces the chance of appliances and end products being exposed to air impurities, preventing operational problems and reducing downtime.

Reduces Maintenance and Repair Costs

By failing to remove the water and vapour build up in your air compressors, it will show rapid signs of corrosion, mould and wear. This may also result in severe damage occurring within your compressor, causing overheating and poor performance.

The most successful way to reduce this risk is through a refrigerated compressed air dryer. The air dryer will prevent this build-up – reducing the costs associated with your routine and emergency maintenance and repair.


Finding the Ideal Refrigerated Compressed Air Dryer

Before purchasing an air dryer, you need to understand your current compressed air system requirements. What pressure does the compressor run at; what pressure flow does it provide:

Maximum Pressure

The maximum pressure listed on your compressed air dryer must be equal to or above that of your compressed air system.

Maximum Flow Capacity

The maximum flow that your compressed air system can provide must be matched or less than that of your compressed air dryer. If you purchase a refrigerated compressed air dryer that cannot provide an adequate maximum flow, it will result in big pressure drops in your system.

If you require a flow capacity of less than 50 CFM, the EMDRY50 Refrigerated Compressed Air Dryer will provide optimum results. For larger flow capacity requirements of up to 10 CFM, the EMDRY100 Refrigerated Compressed Air Dryer would be ideal.

If you want to find the right refrigerated air dryer for your compressed air system, contact the team at Able Sales at one of our showrooms in Perth, Brisbane or Melbourne. Alternatively, you can speak to our specialised team by calling 1300 793 001.
