Refrigeration Dryers

Refrigeration Dryer

One of the important and main parameters in the compressed air industry is the issue of compressed air quality.

Industrial managers use compressed air drying systems to reduce costs caused by the harmful effects of compressed air humidity.

The main destructive effects of humidity in the compressed air system:

Formation of deposits in compressed air pipelines, corrosion in pipelines and pneumatic equipment
Increasing repair costs of pneumatic parts and equipment
Creating errors in the measurement of instrumentation equipment, reducing quality in production
Increased costs due to the presence of moisture in the compressed air system

How refrigeration dryers work

Refrigeration dryers work like home refrigerators using a refrigeration cycle and cool the air up to 3 degrees Celsius.

They also perform distillation and separation of water from air during a process.

Then the air reaches the temperature of the air entering the dryer and is directed to the consumption system.

A dew point of 3 degrees means that no dew will form until the compressed air temperature reaches below 3 degrees.

This amount is suitable for the air required in pneumatic jacks.

These types of dryers are used due to the freezing of water up to the dew point of 3 degrees Celsius, and they generally do not require special maintenance and repairs.

An example of the operation of the dryer in the compressor

The screw compressor with a power of 37 kW has a production capacity of about 6000 liters per minute at a pressure of 8 bar.

At an ambient temperature of 25 degrees Celsius and a relative humidity of 70%, this compressor produces about 6.5 liters of water vapor every hour, which after being compressed by the compressor about 75%, is condensed into small water droplets. It is injected into the consumption system.
