Page 18: Function Description
EN | User Manual Technical product description Function description The dryer dries the compressed air supplied by the compressor and makes it available for industrial use. If so, installed up- and downstream fi lters purify the compressed air, feeded to resp. dissipat- ed from the dryer. - Page 19 EN | User Manual Technical product description Expansion phase During the expansion phase the pressure in the right chamber is released via the muffl er down to ambient pressure within just a few seconds. The outfl ow of the compressed air becomes noticeable due to a sudden powerful fl ow noise at the muffl er.

Page 20: Available Options
EN | User Manual Technical product description Available options The following options are available for the dryer: ◊ Start-up device ◊ Outside installation ◊ Auxiliary heater ◊ Bypass line ◊ Signalling contacts of control system ◊ Compressor synchronisation ◊ Dewpoint-sensing control ◊... - Page 21 EN | User Manual Technical product description transmission of operating signals and for the output of dewpoint alarms. Compressor synchronisation Compressor synchronisation helps reduce energy costs, as the dryer can be operated inde- pendently of the compressor. When the compressor is switched off, the regeneration gas return ensures that regenera- tion is continued, as soon as a certain compressed air volume is reached behind the dryer.
- Page 22 EN | User Manual Technical product description 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.

Page 31: Start Up Dryer
EN | User Manual Start-up Start up dryer Warning against sudden air ejection! During expansion the pressure is released suddenly through the muffl er: ◊ A loud cracking noise occurs which can injure your hearing. ◊ Particles carried in the air fl ow act like bullets and can injure your eyes or skin. - Page 32 EN | User Manual Start-up Operating the dryer for the fi rst time (or after a change of drying agent) separately Depending on the transportation and storage conditions, the drying agent in the chambers can already be loaded with humidity from the environment. At each fi rst start-up it makes sense therefore to operate the dryer from some time separately from the compressed air system.
