In the design developed by CHRIST, the ice condenser is placed directly below the drying chamber. Through the large opening ideal cross section are created for the dissipation of the water vapour.
A high pressure difference between drying and ice condenser chamber can only be avoided if sufficient cross-sections are available during drying to cope with enormous vapour quantities. With this in place the efficiency and economic operation of the unit is greatly increased. Temperature-sensitive materials can be dried safely with this optimized design.
