Ice Prevention

Ice Prevention – Dehumidification & Moisture Removal

Chilled food distribution centres and commercial cold stores present their own unique issues to deal with. Anywhere that reduced temperatures are required to protect or store chilled or frozen products, has the potential for serious issues in relation to:

  • Ice and snow inside the cold store
  • Risk of falling ice
  • Frost shock on product
  • Failure of door mechanisms
  • Increased running costs of refrigeration plant
  • Increased defrost cycles
  • Health and Safety

Each time a door is opened to a cool or cold area, air and moisture enter from any adjacent untreated source. This air is then rapidly cooled and the moisture contained within it is deposited on the coldest surfaces. Dependant on the temperature in the room, this moisture will then appear as condensation or frost.

This will undoubtedly lead to:

  • Increased downtime
  • Lower production rates
  • A higher health & safety risk
  • Increased costs

     

The use of a dehum desiccant dehumidifier in these instances deals with the moisture at source and the dehum units themselves create a low dew point in the air in any adjacent areas. This means that when the doors into the cold areas are opened, there is insufficient moisture to condense or freeze on any of the surfaces.

Simple dew point control built into the control software in the dehum units ensures that only the minimum amount of energy is consumed to create the condition needed to overcome the risk.

We have a range of dedicated cold store machines which have been developed to deal with the rigours of installations in these types of hostile environments and effectively manage the humidity within cold storage.

Blast freezers and spiral freezers also benefit from the application of a dehum unit. Ice is formed as part of the cooling process and loads include moisture leaving the product if unwrapped. Due to the feed belts also having open apertures, there can be high levels of moisture infiltration.

The ice formed by these high moisture loads presents a serious issue and can lead to the need for a total shutdown of the line. Time then spent de-icing reduces production throughput and costs time and money.

At dehum, we have a unique approach to these applications, and typically our design will allow the lines to run longer so that production can continue with fewer interruptions. Result? Increased production and direct savings.
