==Definition== | |||
The '''Refrigerated Air Dryer''' is used for maintaining comfortable moisture level in the atmosphere. | |||
==Characteristics== | |||
* Adopted to obtain CFC free environment friendly refrigerant system of R134a & R404 | |||
* Includes a fine filter combination with an auto air drain for effective separation of dust, oil and moisture for true dew point | |||
* Lowest achievable dew point | |||
* Obtains least differential pressure drop across the complete unit including fine filter combination | |||
* User friendly control panel | |||
* Supplied with automatic expansion valve and hot gas bypass system for continuous duty operation even in under load condition for certain model | |||
* Compact design with maintenance friendly workmanship | |||
* Vast range with air cooled and water cooled version | |||
* Backed by efficient after sales service with easy spares availability | |||
==Advantage== | |||
* A refrigerated air dryer will remove liquid condensate from your compressed air which will protect your equipment and process from the damage moisture can cause. | |||
* All dryers have high energy saving copper heat exchangers and stainless steel condensate separators | |||
* Auto alarm and shut down safety systems help to protect the refrigerated air dryer in the event of a malfunction or excessive temperature | |||
* Electronic auto drains ensure condensate is effectively removed. | |||
==Feature== | |||
* Constant Pressure | |||
* Dew Point | |||
* Low Pressure drop | |||
* Upto 5000 CFM | |||
* Low Pressure Dryer | |||
==Classification== | |||
There are 2 different kinds of '''Refrigerated Air Dryer''' widely available in the global market. These are: | |||
* Economy/Compact Refrigerated Air Dryer | |||
* High Inlet Temperature Refrigerated Air Dryer | |||
==Economy/Compact Refrigerated Air Dryer== | |||
[[File:Rdc_refrigerated_air_dryer_sm.png|thumb|200px|right|Economy/Compact Refrigerated Air Dryer]] | |||
* It uses aluminum cooling heat exchangers | |||
* It produces the lowest pressure drop ratings in the compressed air industry. | |||
* These compact refrigerated air dryers alow for great space savings. | |||
==High Inlet Temperature Refrigerated Air Dryer== | |||
[[File:Aht_dryer_sm.png|thumb|200px|right|High Inlet Temperature Refrigerated Air Dryer]] | |||
* It is used for high inlet air temperatures (up to 210°F). | |||
* It eliminates the need for a separate aftercooler, moisture separator, and particulate filter. | |||
* It is Designed for applications in environments with high ambient temperatures. | |||
* It is ideal for when a high inlet air temperature dryer is required. | |||
