Model SQ1 -Steam QualityTest Kit
The SQ1 Steam Quality Test Kit has been designed to comply with EN 285 with a single improvement to the methodology. It should be noted at the outset that EN 285 specifically allows alternative procedures, provided that they have been calibrated against the standard methods. Instead of the non-condensable gas test being as described in the standard, we provide a condenser system which we have found to be safer, more robust, easier to use (less subjective), and more repeatable. The objective is to separate non-condensable gases from steam and the disadvantage of the standard method is the subjective adjustment of steam flow to prevent localized boiling and therefore the collection of non-condensable gases from the water being used to condense the steam. By using a condenser, the steam does not come into contact with the water and eliminates this subjective and variable aspect.
Condensers tend to be the preferred method for test professionals, though the disadvantage is usually the need to modify pipework in the plant room to have access to a cold water supply. With our system we provide a small submersible water pump, which can simply be dropped into the sterilizer header tank or a bucket of cold water.
The test kit was designed by field engineers, primarily for their own use and has been comprehensively field-tested. A detailed manual is provided, giving details of the test points required, test procedures and an Excel calculation for establishing dryness values etc. It should be noted that the dryness value measurement is not restricted to a minimum value as will be found with some test kits.
