Why Dry Air?
Most of the pneumatic system consist of tiny orifice. Hence must to have processed dry air to protect precision pneum valves, cylinders etc. from fine dust; burnt hydro carbons, C moisture particles.

Types of Air Dryers

Desiccant Air Dryer Refrigerated Air Dryer

Desiccant Air Dryer :

• It gives complete dryness as per ISO-8573 which is called instrument quality air.
• Atmospheric air which is not pure is sucked by air compressor & pressurized stored I(roman numeral 1) receiver tank.
• Air Dryer process this impure air & remove dust, oil & moisture content to avail Pure & dry air.
• Principal : Pressure swing absorption.
• Media : Activated Alumina
• Working : It contains twin tower filled with activated alumina elements which works one at a time by auto control sequential timer & valve kombi system.
• It has build in pre & post filter to remove dust & oil particles.

Uses: Pharma, Food & Beverages, Painting, CNC & Laser Machine, Laboratory, Instrumentation, Gas, Printing, Air Tools, Defence, Chemical & Refinery, Automobile etc.

Special Features

• High dryness, pressure dew point of - 40°C or below
• Low power consumption
• Precision timer & valves
• Easy & economical maintenance
• Range : 50 CFM Volume to 10,000 CFM Volume, pressure: 3 bar to 70 bar

Advantages :

• Protects pneumatic cylinders; Valves, precision equipment controls from malfunctioning
• Improves sharpness in final finish & look c Protects quality of material
• Gives continuously instrument quality pure & dry air
• Safe for critical applications like CNC; Food & Beverage Pharma, Research Lab etc

Refrigerated Air Dryer :
Compressed air contains moisture, dust & oil vapour in gas form at high temperature. To make it use worthy it is treated in Air Dryer unit.

Refrigeration energy is used to cool the compressed air at very low temperature. Condensed mass forms droplets of water & oil vapour & being trapped in built in Moisture Separator which is flushed out through Auto Drain valve and allows pure air to pass through outlet connection.

The dryness achieved in pressure dew point of + 3°C


Applications : Automobile, Food, Cement, Paper, Pneumatic Tools, CNC Machine, Foundry, Hospital, Packaging, Painting, Pharma, Power plants, Rice mill, Textiles, Pharma etc.

Air when compressed, collects dust & water from atmosphere, oil from the compressor & rust from the Receiver, After cooler, pipelines, etc. This compressed air can be used only after removing these contaminants by installing online separators & filters.

The heavier solid & liquid contaminants get separated in the After cooler Separator and the Air Receiver for fine filtration of light solid & liquid.The second stage of separation is done by passing the air through Filters, porous ceramic elements get clogged fast leading to higher pressure drop.

Hence, we have now developed a Filter Element fabricated from S.S. screen wire mesh which gives lower pressure drop and requires only occasional cleaning.



PREFILTERS & MICRO FILTERS FOR COMPRESSED AIR/GAS
Removal of liquid aerosols is more complex & difficult and is achieved by the principle of coalescence i.e. forcing the aerosol to merge with each other. This is done passing the air through a glass micro fibre medium where liquids are collected by the fibres, through the processes of inertial impaction, interception & diffusion. Once collected, the micro liquid particles adhere to the fibre surface and gradually build-up into bigger coalesced droplets which move along the fibres till they attain mass which makes them break away from the fibres. They are driven to the outside of the filter by the air stream, collected at the outer foam barrier and drop out from the filter element at the bottom. The outer foam also does not allow the droplets to re-entrain into the air stream. Two Filters are generally used in series - Prefilter & Microfilter, for removal of larger & smaller aerosols, respectively.

The Basic Version
Pressure differential indicator

• Shows the current pressure drop across the filter

High performance filter element

• Ensures reliable filtration with low pressure loss.
• Optimum filter efficiency even at low airflows down to five percent of nominal
• Reliable element to housing seal prevents unfiltered air bypassing the element

Filter housing

• Has extraordinary advantages
• Long life because it is epoxy coated
• Inside and out (verified in 1000 hour salt spray tests)
• Easy removal for filter element changing
• Low pressure drop because of optimized air flow
• The conical bowl and turbulence-free lower filter zone prevent condensate from being picked up with the air flow
• Audible warning if the housing is opened under pressure
• Automatic condensate drain ...
• .. with floating level sensing

Autodrain is designed for automatic condensate removal from Compressed Air System. Ideal for use with Air Filters

Automatic Signal lockup relay is I I designed to automatically lock I I up the transmitted signal when! I the supply Pressure fails to I 12 PSIG above signal Pressure.

Combination of High Pressure filter and Regulator.
