Presentation Transcript

    1. HMD Series Membrane Dryers Provide dew points from -40°F to +40°F, -40°C to +5°C

    2. Easy to Install and Operate Works without moving parts, consumables, or external power source Light weight – can be installed in piping without additional support Constructed of non-rusting parts – suitable for indoor, outdoor and severe environments (corrosive, explosive, high and low temperatures) Features: Standard Housing: ABS polymer shell with aluminum ends Optional Housing: All stainless steel Pressurized air is inside the membranes Maximum working pressure: 300 psig, 21 bar Maximum inlet temperature: 150°F, 66°C

    3. Suitable for Many Applications Printing Presses Mail Sorting Machines Dental Air Packages Electronic Testing Equipment Coordinate Measuring Machines

    4. How it works

    5. Permeation Compressed air enters the center of the membrane tubes Water vapor moves from inside of the tubes (area of high vapor pressure) to outside of the tubes (area of low vapor pressure)

    6. Selective Permeation Each gas will pass through the membrane at its own characteristic rate. Selective Permeation: Water vapor diffuses through the membrane wall faster than other gases.

    7. Prefilter Packages Keep the membrane dryer clean and oil free with an optional prefilter package Three year warranty The standard one year warranty is extended to three years when the dryer is installed with an optional prefilter package. Prefilter Packages Include: Mounting brackets Interconnecting piping Choice of horizontal or vertical mounting Prefilters Include: Automatic Drain Differential pressure indicator which signals the need for element replacement Choice of One or Two Prefilter Packages

    8. Two Prefilter Package One Prefilter Package Two Prefilter Package For highly contaminated systems or where the highest level of purity is required Includes: Hankison HF Series Grade 7 Air line filter Hankison HF Series Grade 3 ultra high efficiency oil removal filter For normal operation Includes: Hankison HF Series Grade 5 high efficiency oil removal filter

    9. Competitive Comparison Hankison: Patented internally generated purge Each fiber generates its own sweep Better sweep air distribution within the module Lower purge rates (particularly at lower dew points) Competition: Externally generated purge Difficult to distribute sweep air uniformity Lower efficiencies
