Plant Steam for humidification
Plant Steam for humidification
(OP)
Looking at a low grade clean room (ie less than Grade D, Class 100,000), for tablet forming. Air conditioning is only filtered to EU9. However, client has specified the use of Clean steam for humidification, generated from purified water supply.
Bearing in mind that the rh required is only 37% the humidity load is minimal especially since the system is approx. 80% recirc. Also, the 20% fresh air will contain contaminants which won't be removed by an EU9 filter. It seems to me that use of clean steam is over the top unless anybody can advise particular problems with injecting plant steam into the air stream.
Any advice gratefully received. Thanks.

He probably is taking safe bets , just to avoid to be taken by his own QA/QC department later on.

Grim, I would say the decision rides on what type of water treatment is employed. You can take away the morpholine and reduce phosphates (which can also contribute to odor even if they don't carry over) and watch your plant degrade a lot quicker, or you can supply clean steam. It may be a good application for an electric humidifier. Dristeem has them. You can probably use an RO or RO/DI water makeup if the building has it.
