The dehumidication of small and average-sized quantities of polymers may be perfectly carried out with the DD 30 and DD 60 series dehumidifiers. Although these machines have only one silicate cartridge, if the plant is correctly dimensioned, it is possible to easily reach DEW POINT even at 40°C. The temperature control of the dehumidification process is assured by microprocessor system, with a visualization on the panel of the operations carried out and alarms in progress. Silicate regeneration is entirely automatic, the cycle times being personalized by the manufacturer for each machine with the industrial hopper capacity with which it has been fitted, thereby obtaining the maximum efficiency with the least energy expenditure. The original graphics of the control panel facilitate the operator in setting the optimum process temperature, also indicating the minimum stay time in order to obtain a good dehumidification of each material.
