Air dryer

In simple word Air dryer is a machine, device, or a type of equipment which is used as Industrial as well as a Residential/Home Applications, to remove moisture (forced, dry or hot) from compressed air. Most commonly, Air dryers are used in industrial application in many industries like Hospital, Textile, and Telecom Industries etc. Air dryer process concentrates atmospheric contaminants, including water vapour. Nowadays equipments are very costly and Air dryers prevent them from rusting and corrosion, which can be caused by unnecessary moisture. It also prevent from the rid of moisture which can affect the attachments, colour and the finish of coats and paints. Air dryer works by cooling a warm and moisture full air by 3 degree and separate air and moisture, than through water-trap separated water removed.

4.     Membrane
Refrigerant: Refrigerant is a material or combination, usually available either in gaseous or fluid form. It absorbs heat or moisture from the air and provides cooling when combine with other material like compressor or evaporator. Refrigerant is the main source for freezing, air conditions, or refrigeration. Air conditioners we use in our home, office contain refrigerant inside copper coil. Refrigerant absorbs the warm air from the inner environment and pass that outside where a fan blows hot air over the coil.

Regenerative desiccant: It is also known as "regens" or "twin tower". Regenerative desiccant Air dryer use to bring dew point pressure of compressed air to level where water will no more condense or we can say it remove the water from compressed air as much as possible. An expected dew point by regenerative dryer is -40°C (-40°C) and required is dependent on dryer but in some -70°C is required.

Deliquescent dryer: It is also known as single tower dryer it is used to remove the harmful water, natural gas and waste gas from compressed air. Deliquescent dryer provides automatically the dew point approx 20°F lower then air temperature at the vessel pipe. Deliquescent dryer protect from freeze-ups in winter and from liquid in the summer. Deliquescent dryers have non moveable parts and they don’t even need electric power for the operation can be used at dangerous and risky locations. Performance of a Deliquescent dryer is highly depending upon air temperature or gas being processed. Collar temperature is positive performance result.

Membrane: As like other Air dryer membrane is also absorbs moisture or water vapour from compressed air. First Compressed air filtered with a high-quality merge filter and from there filter removes moisture, liquid water, oil and other matters from the compressed air. Filtered air will pass through centre bore of hollow fibres and separated water vapour will pass from outside surface of the fibres. Membrane dryer are designed to work 24*7 and 7 days of the week they don’t even need the electricity to operate and that is why membrane dryer are very reliable.
