DESSICA DIA systems are modular and adaptable air dehumidification units specially designed to meet the requirements of users in the food processing industry :
• hygienic & solid construction made of AISI 304L or 316L stainless steel sheet, 0.12-inch-thick, smooth and
non-sticky inside panel
• made with food contact material (ANIA certificate) for all parts in contact with process air
• easy access with dedicated maintenance doors


  • Modular and adaptable
  • Hygienic and solid construction
  • Made with food contact materials
  • Easy access with maintenance doors
  • Patented Energy Saving System



DESSICA systems uses two independent and countercurrent air flows through the desiccant rotor, with a slow and continuous pace :
• the main air flow (process air) is dried
• the secondary air flow (reactivation air), of lesser volume, is used to evacuate the moisture retained by the desiccant rotor
Two fans set in motion both air streams. Silica gel is a high- performance hygroscopic material able to retain the moisture content from ambient air. By floating through the rotor, the humid air loses its moisture captured by the silica gel material. The dry air
is then totally usable. Reactivation air purpose is to evacuate the moisture captured by the silica gel in the rotor. The air is brought
to an approximate temperature of 210°F to 320°F (100°C to 160°C) and then crosses the rotor against the wet air flow to remove the moisture retained in the silica gel. The moist reactivation air leaves the dehumidifier to be evacuated outside the building or any other
