Measurement of Dew Point Temperature in the Fruit and Vegetable Industry

Application Area

Measuring the dew point temperature of compressed air systems to ensure the proper operation of the dryer and automatic irrigation equipment at fruit and vegetable industry enterprises.

The operating dew point temperature of a refrigerated dryer is about 3-5 ºC. There are various reasons why the dew point temperature may rise and, as a result, water may enter the system, which in turn can lead to significant technical and economic problems.

After installing the dew point sensor after the dryer, you will be confident that at the moment of a dryer malfunction, you will immediately receive an alarm signal so that the system operator can take quick action before water enters the system.

A major problem in this industry is the low awareness of users about the high costs associated with water entering the compressed air system.

Maintaining good compressed air quality reduces costs for all pneumatic components in the system.

Advantages of Using Our Products:

Using our products at fruit and vegetable industry enterprises provides the following advantages:

• Ensuring proper operation of the refrigerated dryer
• Detection of failures during automatic purges
• Identification of open or partially open bypasses that allow moist compressed air to pass through the dryer
• Receiving an alarm signal at the moment of a malfunction caused by an increase in dew point temperature
• Significant cost savings by controlling the required humidity level in compressed air systems and preventing the following problems:
• production process stoppages
• failures of pneumatic components such as solenoid valves, cylinders, etc.
• corrosion inside compressed air pipelines leading to system failure
• bacterial growth in a high humidity air environment and subsequent risks to the consumer
