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
Heated blower purge desiccant dryer mostly uses air from an external heated bower, so it costs few compressed air. Reference performance: Max. compressed air consumption: 0~2% Max. inlet temperature: 45°C, 113°F Max. inlet oil content: 0.01 ppm High quality desiccant: High performance desiccant Pressure dew point: -20~-70°C, -4~-94°F 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
Compressed heat purge desiccant dryer uses the heat from compressed air itself to regenerate, so external heater is not required, and it barely costs compressed air. Reference performance: Max. Compressed air consumption: 0~1% Max. Inlet temperature: 120~170°c, 248~338°f Max. Inlet oil content: 0.1 ppm Max. Working pressure: 10 bar; optimum: 7 bar; various working pressure is customizable High quality desiccant: High performance desiccant Pressure dew point: -20~-70°c, -4~-94°f 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 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.
