Benefits of using a desiccant system

  • 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 occur 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. Downtime 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 has a particular advantage with the Seibu Giken rotor which is effective throughout the whole temperature range of reactivation.  This allows the use of heat reclaim or hot water for unit capacity.  The ice rink case video is one such example.
