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: 45C, 113F Max. inlet oil content: 0.01 ppm High quality desiccant: High performance desiccant Pressure dew point: -20~-70C, -4~-94F Max. pressure drop: 0.21 bar Working pressure range: 4-10 bar, optimum: 7 bar/102 psi Robust and compact design: Forklift slots, lifting eyes Controller: Electronic control board Time-based steering Heater: Made of stainless steel Nickel-plated to avoid corrosion Galvanized piping with flanged connections: Easy maintenance and less chance of leakages Butterfly valves: Good quality butterfly valves Filters (optional): DP offer integrated filters for desiccant dryers Pre-filters could eliminate oil contaminant from compressed air, increasing lifetime of desiccant. After-filters could eliminate dust
