Moisture control in the fruit and vegetable sector

Dew point monitoring in the compressed air line to ensure dryer performance and automatic flushing for companies in the fruit and vegetable sector.

The Dew point of a Refrigeration dryer is usually around 3-5° Ctd. There are a number of factors that can lead to an increase in the Dew point, which can result in water entering the system and causing significant technical and economic problems.

By installing a Dew point sensor downstream of the dryer, you can ensure that you receive an Alarm when a dryer problem occurs so that you can act quickly before the water enters the system.

The big problem in this sector is the lack of awareness among users of the high costs that can be incurred by water in the compressed air line.

Maintaining good Compressed air quality reduces costs for all pneumatic elements in a system

Advantages

Ensuring proper operation of the Refrigeration dryers

Recognising errors during automatic cleaning processes

Detection of open or half-open bypasses that channel the Humidity Compressed air through the dryer

Alarm message when the Dew point rises

Economic savings by controlling the correct level of humidity in the compressed air system to prevent:

  • Production line stops
  • Malfunctions in pneumatic elements such as solenoid valve groups, cylinders, etc.
  • Internal corrosion in the compressed air lines, which can lead to system breakdown
  • Multiplication of bacteria with high moisture content and the resulting risk to Consumers

We recommend for this application description:

  • DS-52 Dew point monitoring for Refrigeration dryers - 0600 5120 with alarm column
  • DS-400 Dew point monitoring for Refrigeration dryers - 0601 0512 with alarm column

Both kits are plug-and-play systems (everything is pre-wired), both contain two alarm relays. As the more advanced device, the DS 400 is able to connect three additional sensors and record their measurement data.

Special advantages

Ready-to-connect system: everything is pre-wired and ready to use

2 alarm contacts

4...20 mA Analogue output

Fast equalisation time

Option: Data logger (DS 400)

Option: 4 sensor inputs (DS 400)

Option: Integrated Ethernet and RS 485 interface (DS400)

Option: Integrated web server for e-mail alarm (DS 400)
