I am a small packing plant owner. I am going to go making refrigerant air dryer my self. my air compressor details are given below, working press.......8 bar air delivery...........28 cfm inlet air temp........40c req air temp.........8c Air usage.............25cfm Max Pls, tell me what tube sizes I need. Capacity of condenser and eveparator. Tube orifices and lenght. I wish to used solid aluminium cylinder about 5Kg as heat exchange Is it good? Also I hope that cooling coil and compressed air lines make as spiral shape and casting in the aluminium cylinder together. auto drain valve also used to drain the codensed water Thanking you

<...making refrigerant air dryer my self...>

Why? If it fails to perform as design what are the consequences for the business?

Why not buy one instead, and place the risk with the supplier?

Our guest probably has more time than money?

Comp air tubing size should be large enough to keep velocity low so that the air has time to cool down enough and condense water. My first guess is 1" tubing, or four 1/2 tubing run in parallel for the same cross section area.

Since you will deal with liquid and gas flow in the same tubing, be very careful of pitch so you do not collect slugs of water. Make sure that the small drops of condensate flow to a low point and are properly drained so the water does not form slugs and get blown through your system.

If something goes wrong with your invention, I doubt your insurance would pay for any damages. Be careful.
