Air Dryer (Desiccant Air Dryer)

Desiccant Compressed Air Dryer two types ---heatless purge and externally heated purge 1). Heatless purge desiccant air dryer Inlet temperature: 0~45 Celsius degree Inlet oil content: less than 0.01ppm Working pressure: 0.6~1.0Mpa Dew point: -20~-70 Celsius degree Purge air: less than 12% Desiccant: Activated alumina & molecular sieve Purge mode: Heatless purge Working method: Continuing alternation between two towers Working periods: T=10~20min. Control mode: Micron computer auto controlling Installation mode: Indoor, non-basement 2). Externally heated purge air dryer Inlet temperature: 0~45 Celsius degree Working pressure: 0.6~1.0Mpa Dew point: -40~-70 Celsius degree Purge air: less than 4~6% Desiccant: Activated alumina & molecular sieve Purge mode: Externally heated purge Working method: Continuing alternation between two towers Working periods: T=120~140min. Control mode: Micron computer auto controlling Installation mode: Indoor, non-basement

Low Dew Point Combined Compressed Air Dryer Working pressure: 0.6~1.0Mpa Pressure drop: less than 0.05Mpa Inlet temperature: less than 45 celsius degree (Normal temp. type) Inlet temperature: less than 80 celsius degree (High temp. type) Dew point: -40~ -70 celsius degree Cooling watre temperature: less than 32 celsius degree (water cooling type) Purge air: 3~5% Control mode: Micro-program controller Installation mode: Indoor, non-basement

Supplier: Compressed air dryer, desiccant air dryer, refrigeration air dryer, air filter, nitrogen generator, auto drain valve, level sensing drain valve.

Air filter compressed air filter 1). Separator filter (HF9) For bulk liquid removal plus a 3 micron coalescer (5ppm w/w maximum remaining oil content) Two-stage filtration * First stage: two stainless steel orifice tubes provide 10 micron mechanical separation * Second stage: in-depth fiber media captures solid and liquid particles to 3 micron 2). Air line filter (HF7) For removal of liquid water and oil; removes solid particles to 1 micron (1.0 ppm w/w maximum remaining oil content) Corrosion resistant inner and outer cores Two-stage filtration * Firt stage: captures larger particles with alternate layers of fiber media and media screen * Second stage: coalesces aerosols and captures solid particles with multiple layers of epoxy bonded, blended fiber media 3). High efficiency oil removal filter (HF5) For coalescing fine water and oil aerosols; removes solid particles to 0.01 micron (0.01 ppm w/w maximum remaining oil content) Corrosion resistant inner and outer cores Two stage filtration * First stage: multiple layers of bonded, blended fiber media for fine coalescence * Second stage: multiple layers of bonded, blended fiber media for fine coalescence Outer coated, closed cell foam sleeve 4). Ultra high efficiency oil removal filter (HF3) For coalescing ultra-fine oil aerosols; removes solid particles to 0.01 micron (0.001 ppm w/w maximum remaining oil content) Corrosion resistant inner and outer cores Two stage filtration * First stage: coated, closed cell foam sleeve acts as pre-filter and flow disperser * Second stage: multiple layers of matrix blended fiber media for ultra-fine coalescence Outer coated, closed cell foam sleeve 5). Oil vapor removal filter (HF1) For removal of oil and hydrocarbon vapors normally absorbable by activated carbon; removes solid particles to 0.01 micron (0.003 ppm w/w maximum remaining oil content) Corrosion resistant inner and outer cores Two stage filtration * first stage: stabilized bed of finely divided carbon particles removes the majority of the oil vapor * Second stage: multiple layers of fiber media with bonded micro fine carbon particles remove the remaining oil vapor Multiple layers of fine media prevent particle migration Outer coated, closed cell foam sleeve prevents fiber migration Designed life is 1000 hours under rated conditions.

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
