Produits

  • Supply of an air dehydration system by silica-gel desiccant wheel type DT-1500 ICF
  • The installation was carried out inside the cold room at an operating temperature of -22 ° C to treat 1500m3 / h of air.
  • The regeneration air is taken from the fresh quay at + 5 ° C and the humid air is discharged into the attic.
  • The installation was fitted with a clock to stop operation at night and on weekends in order to optimize energy consumption.
  • Dehydrators working on negative DESSICA atmospheres have a particularly low consumption (6.1 kW).

Installation
