Looking at the data sheets the evaporation for the Saz 18 in 2006 was 67.73% when it went into stainless. In 2007 the data sheet reflects evaporation of 51.94% and in 2008 54.08%. First off why would the evaporation given it is in stainless be anything other than 67.73% and secondly why would it drop? Lastly why would anything evaporate out of sealed stainless ( 2007 to 2008 )?
What is it I am failing to grasp????
