FOOD – Cold Chain

Cold chain Benefits

  • Prevention of Ice and condensation
  • Save energy
  • Reduce defrost cycles
  • Maintain specified humidity without reheat
  • Dry to below -50Cdp


Ice, frost and fog build up occurs whenever warm air comes into contact with a cold environment, i.e. when doors are opened and closed in a refrigerated store. Ice and frost build up means that regular defrosting of the store is required; this costs the company time and money.

Without dehumidification the  ambient air entering the building through the conveyor feed apertures will lead to ice and frost formation which will eventually lead to the malfunction of the  conveyor machinery and associated proximity /  optical sensors. Frost build up on the product is undesirable.


The icing, fogging and frost problem can be virtually eliminated by the installation of a desiccant dehumidifier to provide dry air into the plant. This will create a much safer and more pleasant  working environment resulting in increased productivity. Down time for defrosting and cleaning will be drastically reduced. The working environment will be more worker friendly. A dehumidified environment will pay for itself in many ways.


DST have a particular advantage with the Seibu Giken rotor which is effective througout the whole temperature rance of reactivation.  This allow the use or heat reclaim or hot water for unit capacity.  The ice rink case video is one such example.
