Compressed Air/Gas Dryers
MGS manufactures complete range of
Heatless Compressed Air Dryer Systems and Gas Dryer Systems.
These compressed air and gas dryers find use in majority of
industrial compressed air systems and applications.
Heatless Type Dryers do not require any heating of the
desiccant for regeneration and therefore are very simple in
design and smooth in operation. Heat Reactivated Dryers have
become obsolete due to their high operating costs and high
In Heatless Dryers two vessels filled with desiccant are
provided which cycle automatically, producing Dry Air
continuously. In these units, wet air enters the bottom of one
vessel and passes upward through the desiccant bed where the
moisture is absorbed. The clean dry air comes out from the
A small portion of the dry air is passed downward through the
desiccant bed in the second vessel which is under
regeneration. This moisture laden purge air is then vented out
to the atmosphere. The purge loss is around 5% of the total
air flow rate. At preset interval, the vessels changeover
automatically and the Dry Air is available continuously
without any surges. The purge air loss is around 15% if dew
point of (-) 800C is required.

The Ideal Compressed Air System
In selecting the most efficient and economical compressed air
dryer for any system, the major consideration is the lowest
dew point, the dryer can maintain for the flow of compressed
air you require. "Dew Point is the measure in air, and it is
the temperature at which moisture starts condensing from the
air into a liquid state. The lower the Dew Point, more dry is
For industrial applications dew point better than minus 17oC
(moisture content around 0.1%) is generally considered quite
satisfactory, but some of the applications require dew point
of the order of minus 60oC (6.5 ppm moisture) also. It must be
kept in mind that lower the dew point, higher is the cost of
compressed air. Hence proper selection of the dew point gives
the most economical operation.
Air from a compressor is loaded with moisture and damaging
contaminants. The sketch on back side typifies a compressed
air system designed to solve the contaminates problem and to
provide clean, dry air.
A separator or pre-filter should be installed just before the
dryer to remove moisture which carries over from the first
after cooler/separator, or which becomes entrained between the
separator and the dryer. Ideally, this pre-filter (or
separator) should be installed close to the dryer so that
moisture does not have an opportunity to condense and become
entrained prior to entering the dryer.
The system dew point must be lower than the lowest temperature
your lines pass through. If not, moisture will condense in the
lines. Also, certain applications are subjected to tighter dew
point restrictions for proper operation. For instance,
precision instrumentation always requires a (--) 40oC dew
point. Air operated mechanical equipment also require low dew
points to ensure against failure and provide long life.
HIGH PRESSURE AIR / GAS DRYER
For various industrial applications where Air / Gas at high
pressure in dry form is required, Mas Gasair Systems offers
High Pressure Air / Gas Dryers. High Pressure Dryers are
Heatless type. Some of the High Pressure
Industrial Applications are:
- Pet Blowing Machine
- Air Circuit Breaker
- High Pressure Gas Filling
- High Pressure Testing
- High Pressure H2 for Turbine Cooling
- High Pressure Generator Starting
- High Pressure Process Gas Applications.
- Fully Automatic
- Eliminates need of costly heaters for regeneration,
and also no cooling water requirement
- Low temperature operation reduces corrosion in towers
and desiccant lasts longer
- Automatic re-pressurizing equalizes desiccant vessels
pressure before changeover. So Desiccant movement is
- Desiccant life is around 5- years.
- Power requirement is Single-Phase, 60 watts only.
