Heated purge desiccant dryer uses compressed air as a purge, but its regeneration process also uses the energy from an external heater, so it costs moderate compressed air.
Reference performance:
Max. compressed air consumption: 6%
Max. inlet temperature: 45°C, 113°F
Max. inlet oil content: 0.01 ppm
