Page 18: Function Description
At the same time the other chamber is prepared for a renewed take-up of humidity. This process is called regeneration. The regeneration is subdivided into three phases: expansion, dehumidifi cation, and pres- sure build-up. With the dewpoint-sensing control option, the regeneration phase is followed by a standby phase. KE-MT 120-600... - Page 19 When the drying agent in the adsorbing chamber has taken up a suffi cient level of humidity, then the switchover between the vessels will be effected between the vessels. Following switchover, the above-described process is repeated, with the adsorption and regeneration now taking place in the respective different vessel. KE-MT 120-600...

Page 20: Available Options
The control system can also be equipped with an optional operation signalling contact with which the dryer operation can be monitored from an external device. Dryers with the optional dewpoint-sensing control are equipped with such a contact as standard. It is used for the KE-MT 120-600... - Page 21 Preliminary fi lters should be installed as close to the dryer as possible. The pipe feeding the air to the preliminary fi lter should be at a slight slope. It is recommended to install an afterfi lter behind the dryer to prevent contamination of the dried compressed air with desiccant particles. KE-MT 120-600...
- Page 22 Pneumatic control Condensate drain systems are installed to drain water that has collected in the preliminary or afterfi lter from the fi lter. There are two distinct types of condensate drain system, namely level-controlled systems and time-controlled systems. KE-MT 120-600...
