Expert Review

Our experts can help

Atlas Copco makes the BEST Variable Speed Drive Air Compressor, plus they offer a FREE FACTORY START UP with each VFD Compressor Purchase.

The VSD technology closely matches the air demand by automatically adjusting the motor speed.  Combined with innovative design of the iPM (Permanent Magnet) motor, this results in average energy savings of 50% and an average cut of 37% in the lifecycle cost of a compressor.  VSD+ works with permanent, in-house designed permanent magnetic motors. 

There are too many reasons why you SHOULD buy a VFD air compressor.  I highly recommend calling any of COMPRESSOR WORLD’s experts to discuss in further detail.

The energy efficiency of refrigerated compressed air dryers

The energy efficiency depends on the internal pressure drop and the electrical power consumed by the dryer.  

Keeping the pressure drop as low as possible

The internal pressure drop is the difference between the pressure of the compressed air at the dryer inlet and outlet pipe.
The lower the internal pressure drop of the refrigerated dryer, the lower the pressure you need to achieve with the air compressor. And the less energy the compressor consumes. 

Our refrigerant dryers are designed to minimize pressure drop and have therefore the lowest energy consumption.


Energy-saving refrigeration system technologies

Maximize your energy savings from the first minute of operation with

  • Variable speed drive refrigerated dryers 
    Compressed air flow fluctuates depending on the time of the day, week, or even month and working temperatures may vary. VSD technology allows to adapt to the fluctuations and saves energy in case of partial load or altering working conditions.
  • Components designed for efficiency
  • Monitoring and control system

How does a refrigerated air dryer work?

Refrigerant dryers are the most commonly used dryers in the industry and consist of an air-to-air heat exchanger and an air-to-refrigerant heat exchanger. The heat exchangers remove moisture from your compressed air by condensation of water within.This is essential to protect compressed air systems and every piece of equipment fed by compressed air from the harmful effects of moisture.

The most important criterion is to keep the relative humidity of compressed air below 50%.

Both air-cooled and water-cooled refrigerant dryers are available. Basically, the dryers cool down the warm wet air coming from the compressor, When the temperature of compressed air reduces, moisture condenses and is drained from the compressed air with the help of a high-efficiency water separator.

After that, compressed air is reheated to around room temperature so that condensation does not form on the outside of the pipe system. This heat exchange between ingoing and outgoing compressed air also reduces the temperature of the incoming compressed air, and as such reduces the required cooling capacity of the refrigerant circuit.
