steam strilizer

we just install new medical sterilizer machines. the steam supply to these machine must be saturated dry steam. but we facing a problem that the steam is wet
so is there any way to prevent the wet steam

Firstly, how do you know that you have wet steam? "Wet steam" is often thrown out as the reason for all kinds of problems. I've known equipment manufacturers, designers, contractors, production people, etc. to drag this out as "the reason" behind all kinds of things. Sometimes, wet steam really is the problem. More often than not, though, it's a convenient smoke bomb to permit the dumping an unrelated problem in somebody elses lap - like yours.

If you do have wet steam at your sterilizers, then you need to find out why. Do you have wet steam everywhere? Is the boiler water chemistry OK? Is the near boiler piping installed and insulated properly? Are the steam lines in your facility all sloped, trapped and insulated correctly? Is there a trap ahead of the shut off valve for the sterilizers so that when they are out of service, there isn't a large pocket of condensate collecting ahead of it?

If all else fails, and the issue is still "wet steam", install a steam separator on the smallest application that is deemed to have the problem. Discharge the trap to the floor, or a bucket. If you get a lot of condensate, and/or the process shows measurable improvement, then wet steam is likely the problem. If there's not much condensate, and/or there's really no change in the equipment performance, then something else is causing the problem.

CSSD,
There are two steams generally used in a steam steriliser.
One is pure(sterile) steam which is used in the chamber for sterilisation application and the other one is boiler steam for jacket. The pure steam generally will be dry because of its very principle of production.(superficial evaporation)

Jacket steam need not be total dry.(Actual dryness fraction should be told, but manufacturers are cunning enough that they don't specify the dryness fraction).

Howevr you can install moisture separator and steam trap just below entry to the autoclave so that you will get dry steam. (For pure steam so far I couldn't find out a sterile steam separator.
