Air Dryer Sizing Method

CR4 offers neither permission nor training to use the telephone to contact equipment suppliers, for that is in the original poster's domain. Go for it; "Nike" (usual disclaimer).

Exactly, contact any of the manufacturers and they will be glad to do the sizing for you.

Thanks for reply.

You may study refrigeration and air conditioning(Bone drying, RH%, Tw, Td, Psychrometry). Air drying is just condensing water vapor and some is centrifuge supported with spiral cavity.

Thanks for reply.

Start with documenting your consumption process... those things that will consume the dried compressed air... And remember that consuming 1,000 CFM in 15 seconds, with no consumption for the next 45 seconds every minute is different than consuming 1,000 CFM evenly over the one minute even though they are both 1,000 CFM consumption processes.

Once you have collected the data, forward it to a local distributor for the equipment you are looking for. They can help you from there.

Thanks for reply. Will take note on the info taught. Thank very much.

Select a drying system that provides throughput capacity which matches the air flow demand of your system.

Example: If the system uses 3,000 SCFM of air flow then the drying system selected must be capable of drying 3,000 SCFM.

If all of the air being produced by the system is not required to be dry then you should consider "point-of-use" air drying equipment at those locations where dry air is required.

If you do not know the system demand and requirements, I suggest you hire an outside specialty company to perform an on-site air system study.

The cost savings realized by knowing process air requirements usually allow enough energy and maintenance savings to recover any dollars invested.

Thank for your reply. Will take note on the info. Thank very much.

The minimum working pressure and maximum air flow of each pneumatic device is first established.

Then all in simultaneous use are added up (with spare capacity) to arrive at a minimum compressor size.

Then match the dryer to the full output of the compressor taking additional account of the 'hot' air temperature from the compressor, the ambient temperature, and the pressure-dew-point required.

The simplicity of your question suggests you do not know much about the subject and need help to select compressors and dryers. In which case you tell the prospective supplier the minimum working pressure, the maximum working flow, the ambient temperature and the pressure-dew-point.

They Will ask additional questions (power supplies, receiver size, redundancy, etc) depending on the characteristics of their equipment (and extent of their expertise) and will tell you what is suitable.

Thank very much for your information and reply. Will look into it.

send me your requirement I will design your air dryer. or send me list of consumers ( instruments as well mechanical, process mixing / cleaning air requirment, air required for tool operation etc. along with future requirement for expansion etc with time also will do. Please do not foreget to right the name of area where air dryer to be installed.
