The SES329 family of  continuous dry air systems are targeted at transformer back fill applications but can be custom engineered for other industrial applications on request. The SES329 is available in four standard sizes up to 50 cfm in both class "D" breathing certified, non breathing certified confirurations. A two stage dryer system is standard producing - 62°C (-80°F) average dewpoint output with 38°C (100°F) air @ 100% RH.  Fixed and variable speed rotary screw compressors provide solutions for shore power and stand alone generator power applications. Otional 99.5% pure top off nitrogen generation is also available.
