DI cleaner (washer) bath temperature | 26 February, 2007

Is there a typical DI cleaner (washer) bath/ spray temperature? (In-line cleaner)

Is there a maximum temperature? I know some parts do tend to have issues like TH electrolytic jackets shrinking. But is there any situations to be aware of?

Bacteria growth issues with increased temperatures? Steam evaporation is an issue. With increased bath temps.

What temps do you use for your cleanter bath / spray cleaners?

Depending on your D.I. system, your maximum temperature concern may be at what temperture it returns to your D.I. system. Hot water may foul you set-up very quickly.

As for maximum tempertures for parts, your biggest concern should be drier section. Many drying sections of cleaners can really get hot.

I have always locked the setpoint at 130-135F 135 being hte max temp most media beds can handle. If you breach/exceed 140 the media will break down or gum up which will cause many probelms for you.

If you�re running chemistry in the wash, the wash temperature will be influenced by the chemical manufacturer�s recommendations. Typically, wash chemistries recommend operating temperatures between 130F and 150F.

If your application is straight DI and the equipment is not closed looped, then 130F to 135 F is normal. If you are close-looping the wash solution, then I would not recommend wash temperatures above 120F for two reasons. First, most ion-exchange resins provide maximum life at temperatures at or below 120F. Second, most ion-exchange resin tanks have a maximum temperature rating of 120F.
