Desiccant air dryer sizing

One type of dryer seen frequently across the world is the regenerative desiccant dryer. To size the desiccant air dryer to match this compressor, we need to calculate of the total CFM, in this case, 20. The max output is no more than CFM or of the total CFM of 20. Considering that most twintower desiccant regenerative air dryers require to purge air consumption, excessive purging and increased compressor wear and tear will result if the dryer is over-sized.

Not matching the dryer size to the application could cost considerably more if the incorrect sizing method is used.

Use our Dryer Sizing Tool below to find a refrigerated or desiccant compressed air dryer to fit your compressed air system. Simply enter in your system speciations and select Find a Dryer and it will return for dryers that match your specifications. When sizing a dryer , it’s important to understand how temperature and pressure affect water content in air. The water vapor content of air varies directly with temperature—if temperature increases, the air ’s ability to hold water increases.

As a rule of thumb, every 20° F rise in inlet air temperature may double the water load on a dryer. From these charts, pick the line which is your lowest operating pressure and read down to the capacity that matches or exceeds your flow rate. In heavy-duty industrial operations, water vapor in compressed air equipment can lead to premature failure, corrosion, frozen air lines, quality control issues and a range of other operational problems.

A desiccant air dryer system purifies compressed air by absorbing moisture. This desiccant is made of a material that really ‘likes’ water, the water sticks to the surface of the desiccant. Buyers can compare features, specifications and prices of multiple air dryers to choose the best. Of the three compressed air dryer types, regenerative desiccant dryers supply the lowest dew point, usually -40ºF an if require as low as -100ºF pressure dew point. Regenerative desiccant dryers are often specified to protect instrumentation and control systems, laboratory equipment or moisture-sensitive process materials.

Adsorption is the process of removing water VAPOR from the air to be dried. Desiccant dryers work on the principle of adsorption. All condensed liquid water should be removed from the inlet air stream prior to reaching the dryer by suitable separators, traps, filters, and drains. The dryer can not be burdened with liquid condensate carry-over.

When considering a heatless desiccant dryer , make sure to account for the extra purge air when sizing your air compressor. Shop for desiccant dryers at Grainger! Air filters are ideal for paint-spraying applications. It removes dust, dirt, water vapor, and oil aerosols that may have bypassed main air filtration system.

Find great deals on eBay for desiccant air dryer. Compressed air entering the dryer must be cooled to at least 120…F.

W per 1cfm for refrigerated dryers —almost times as much! But if you have a desiccant style air dryer in lightly loaded conditions, it may be costing you more than you think. HEATLESS DESICCANT COMPRESSED AIR DRYER. As the above dryer sizing table, the correct dryer for this application,. Carefully read this manual before attempting to operate or perform maintenance on this equipment.

Alpha-Pure - CFM at 1psi Inlet, 6. Pre-filters, located before the dryer , protect desiccant beds from contamination by oil, entrained water, pipe scale, etc. If you would like more information on selecting and sizing a suitable refrigerated air dryer for your application don. Compact Air Dryer is shoebox size. Selecting An Ingersoll Rand.

To regenerate the off-line tower, atmospheric dry purge air flows through the regenerating bed. Purge air dries the moisture laden desiccant beads and is expelled to the atmosphere through the mufflers. Moisture loa velocity, contact time and cycle time determine the amount of desiccant require and the size of the vessels.

Drying Wet compressed air flows upward through the adsorbent desiccant from bottom to top (1). Featuring coalescing prefilters with automatic drains, our desicant air dryers provide a particulate final filter, a moisture indicator, differential pressure indicator and pretested controls. Heaterless Dryer Series 1-1SCFM.

MTA-USA, MHL and SHL dryers are heaterless, twin tower, regenerative desiccant dryers designed to remove water vapor from compressed air and gas streams to a pressure dewpoint of -40°F and lower. The compact size of General’s industrial heatless desiccant air dryers ensures that installation is simple and versatile. The units can be installed in small spaces in either a vertical or horizontal position. Basically, the water will ‘stick’ to the surface of the desiccant , resulting in dryer air. Every once in a while, the desiccant is re-generated.

This is done automatically by the dryer. Kaeser can design a system that will efficiently deliver air quality suitable for your application. Considering the importance of filtration to dryer performance, Airtek recommends that all desiccant dryers be ordered as a complete, factory assembled Air Treatment System.

We manufacture a complete line of refrigerated dryers and desiccant dryers as well as filters, compressed air system controllers, and accessories. One of the most significant drawbacks of twin tower desiccant dryers is their use of the purge air. Typically, a twin tower desiccant dryer uses some to of its capacity to regenerate the opposite tank, making these dryers inefficient and costly to operate. Filtered compressed air enters on-line desiccant -fille drying Tower through valve (A).

Up-flow drying enables the desiccant to strip moisture from the air stream. Clean, dry compressed air exits through (E) to feed the air system. Tower (shown in regeneration mode) with valve (B) close depressurizes to atmosphere through muffler (C). They use desiccant , a water-absorbent substance, to remove moisture and lower the dew point of compressed air as it passes through a chamber.

So, sizing desiccant air dryers is very important. The desiccant is then dried by a purge of hot air. Water Vapor in compressed air equipment can cause many operational problems from equipment failure to quality issues.

Having the right compressed air dyer for your air compressor is a true requirement if you want to extend its life and save money in the long run. Dry air with dew points of either -40°F, -80°F, or -100°F can be achieved. Features and Benefits ALE-27-Littleton,.

Any given material has its own processing requirements, which need to be met without deviation in order for things to materialize as planned.
