The drying body is equipped with a double heating or cooling jacket built in stainless steel and dimensioned to resist a working pressure of 2 bar.
The shape of this jacket is identical to the shape of the dryer. Loading and discharging of the heating liquid is carried out through rotary gaskets with their respective connections to the double jacket. If the heating fluid runs at high temperature, it is advisable to install a third jacket covered by isolating material. This provides energy saving and safety for the operators.
