The SWB^™ Series are shell and tube dryers primarily used in sample gas applications. They can also be used for compressed air applications where the SWB^™ conforms to the dimensional requirements or the required flow rate is higher than what the SWC^™ Series can accommodate. There are four models in the SWB^™ Series, and they can accommodate flow rates up to 600 L/min. The flow pattern through the dryer is bidirectional, allowing for mounting flexibility as the inlet port can be at either end. This series of dryers does not have a built in purge so either an external purge gas source or rerouting dried gas from the outlet for use as purge gas is required. In order to protect the membrane dryer from solid and liquid contaminants, a prefilter (also available from A+ Corporation) should be installed on the inlet side of the dryer.
