Dehumidifiers for Walk in Freezer by Vacker Dubai
In this article, we are briefing about dehumidification for an extreme cold walk in freezers such as 
-20°C temperatures.
Type of dehumidifiers for walk-in freezers
Under such extreme cold conditions, only a desiccant type dehumidifier can be used. The machine cannot be kept inside the freezer room, because the machine itself may freeze. The machine has to be kept outside the room and the air has to be processed and returned to the room. There will be two pipes coming from the freezer to the machine. One will be the intake air and the other will be processed dry air. The machine will process the wet air and will convert into dry air. The dry air is then returned to the freezer room thus reducing the humidity.
