? for Otto

[catman115]

Otto, I know that you are in the food machinery biz. My ? if you can help is "dessicant dryers" I think that they are used in refrigeration units. I found an air compressor that has a dryer on it.. what is that for ? drying the air ? taking oil out ? if you can clarify..thanks.. Richard

Richard,

The food industry typically used a more standard refrigerated air dryer to remove moisture from compressed plant air. Due to the excessive heat generated by most air compressors, there is a lot of condensate generated that must be removed.

A dessicant dryer is a simpler device using a replaceable media (dessicant). Most have controls for a regeneration cycle to offload condensate. The media material (beads) may have to be replaced if you re-commission the system.

Either way, yes, the device "drys" the air. This is most important when using air for sensative instrumentation, or for that matter, painting your classic SeaCraft, where water in an expensive 2 part paint would have destructive results.

Here's an example from Hankinson .

How's that for "off topic"? At least I tied it into SeaCraft.

Otto..I thank you for the reply. I was told that this compressor is a "rotary screw" which I guess is designed to run 24 hours a day ergo the dryer to eliminate the moisture build up. I am thinking of installing it in the garage to run air tools. this thing is a 3 phase 10 horse motor..Manly power with plenty of air !!! It was pure genious how you tied this "off topic" topic to classic sea craft.. thanks again.
