Lectrodryer - Model Type BP - Compressed Air and Gas Dryer Brochure

The Type BP has a closed-circuit reactivation sys-tem that makes it ideal for drying gases without con-tamination from the atmosphere. And this includes typical gases such as hydrogen, nitrogen, helium, argon, and methane. The BP accomplishes this by using dual adsorbers that are heat reactivated for drying compressed air and other gases to dew-points down to –80°F, with reactivation occurring at line pressure.
