There is an industry debate as to whether to install a compressed air receiver tank before or after the refrigerator dryer. Really, it depends on the type of tank you’re looking to install. Wet and dry tank placement comes down to a few important factors.
- Primary tank placement should take place before the dryer for better moisture and surge control.
- Secondary tank placement should take place after the dryer for better storage of clean, dry air.
At Compressor Services, we take great care in when and how to install wet and dry tanks in all the industries we serve.
Key Takeaways
- The most effective placement for wet and dry tanks depend on whether it is a primary or secondary tank.
- Both placements have distinct advantages and disadvantages, depending on your needs.
- Incorrect placement can lead to reduced moisture separation, increased load on dryers and filters, pressure fluctuations, and higher energy consumption.
The Advantages Of Installing A Compressed Air Tank Before The Dryer
You’ll Get A Favorable Dryer Size
The dryer can be sized according to the actual consumption of compressed air, or for the partial flow of compressed air that needs to be dried.
The Drying Of A Non-Turbulent Volume Flow
Placing the tank before the dryer allows moisture-laden air to expand and slow down, reducing turbulence. This steadier airflow improves dryer efficiency and leads to better moisture removal.
Low Compressed Air Entry Temperature
The compressed air can cool down further in the compressed air receiver. As the air cools, more moisture condenses out before reaching the dryer, reducing the load on the drying system and improving overall efficiency.
Low Quantities Of Condensate
The droplets of condensate collect in the compressed air receiver and do not burden the rest of the system.
The Disadvantages Of Installing A Compressed Air Receiver Tank Before The Dryer
Condensate In The Receiver
While it’s true that the condensate stays isolated in the compressed air receiver, it can cause corrosion there. This will add to the wear and tear of your system.
Overload Of The Dryer
The dryer is overloaded any time there is an abrupt, heavy withdrawal of compressed air. The pressure dew point of the compressed air rises.
The Advantages Of Installing A Compressed Air Tank After The Dryer
Dried Air In The Compressed Air Receiver
Installation in this order means that there would be no condensate in the compressed air receiver. This means it operates better with less wear and tear.
Consistent Compressed Air Quality
Even with the abrupt, heavy withdrawal of compressed air, the dew point of the compressed air remains unchanged. This allows for more operational efficiency and less wear and tear.
The Disadvantages Of Installing A Compressed Air Tank After The Dryer
It Requires A Large Dryer Size
The dryer must be designed for the entire effective output of the installed compressor. The dryer is often over dimension if the consumption is low.
Drying Of Pulsating Compressed Air
As a result of their construction, piston compressors deliver a pulsating flow of compressed air. This puts stress on the dryer.
There’s A High Entry Temperature Of Compressed Air
The compressed air comes directly from the after-cooler of the compressor, meaning it may be too hot for optimal moisture removal. Higher temperatures reduce the efficiency of the dryer, because warmer air holds more moisture and is harder to dry.
Higher Amounts Of Condensate
The entire amount of the compressor’s condensate precipitates in the dryer. With systems that contain many compressors, each compressor requires a dryer.
