Page 15: The Process/Regeneration Cycle
The Process/Regeneration Cycle There are two desiccant beds in each of the dryers. While one desiccant bed is on-line in the process air loop, the other is off-line being regenerated. When a desiccant bed is on-line, it absorbs moisture from the process air. The desiccant will become saturated with moisture and need to be regenerated. - Page 16 Safety Circuit Standards Safety circuits used in industrial systems protect the operator and maintenance personnel from dangerous energy. They also provide a means of locking out or isolating the energy for servicing equipment. Various agencies have contributed to the establishment of safety standards that apply to the design and manufacture of automated equipment.
