Desiccant dryer ALM-CDA series

aircleaningcompact

The ALM-CDA cold-regenerating adsorption dryers are used where compressed air has to be dried to a pressure dew point of -20°C, -40°C or optionally -70°C. The series offer compact design and simple operation. ALMiG offers two control systems for the ALM-CDA adsorption dryers: PLC (time-based control) The HDD adsorption dryer has a time-based PLC control as standard. The standard cycle has five minutes of adsorption, followed by four minutes of desorption (removal of deposited water vapour from the desiccant) and one minute for pressure build-up. LCS (load dependent control) The LCS control is a load-dependent control that allows energy savings. Instead of the five-minute cycle of the time-based control, the LCS control has a dew point sensor that measures the moisture content at the dryer outlet. The dryer only regenerates when the set dew point is exceeded. This saves purge air and thus energy. Features and benefits: Welded vessels according to ASME or PED standard. Other standards and approvals on request The use of self-cleaning wedge wire made of stainless steel in the humid area enables an even distribution of the air flow through the dryer with a low differential pressure Indicator lights for on/off function, adsorption, desorption and LED indication of dew point (if a dew point sensor is installed) Use of a high-performance molecular sieve for use in a wide range of conditions Use of standard industrial valves for quick change or maintenance Customised versions available on request Easy maintenance
