Compressed Air Treatment

AFTER COOLERS
[ AIR + WATER ]

AIR COOLED


The compressed air discharged from an air compressor is hot. Compressed air at these temperatures contains large quantities of water in vapour form. If this is not removed, much of it will condense in the distribution system and cause expensive damage to all the equipment and processes, which use the air. As the compressed air gets cooled in the after- cooler, where the cooling media is the ambient air or water from a cooling tower, the water vapour condenses into a liquid form. As an example if an after cooler is not used, a 200 scfm compressor operating at 7bar (g) introduces 170 - 240 liters of water into the compressed air system each day. Atmospheric air is used to cool the compressed air in an air cooled after cooler.


Salient features of Sanpar After Cooler (Air Cooled) :
• Highest quality copper tubes and aluminum fins are used for effective heat transfer and durability
• Low pressure drop (less than 0.1 bar)
• Low noise (less than 60 decibels)
• Low maintenance
• Silver brazing rods used for efficient thermal conductivity
• Highly reliable fan assembly with protective guard
• More than 10 standard models to choose from to meet individual requirement
• Compact models: occupies less floor space
• Higher models on request

Technical specification [Air Cooled]
• Air inlet temperature : 120° c
• Ambient temperature : 45° c
• Outlet air temperature : 10° above ambient
• Operating pressure : 7 bar (g))
