In the fields for specification of the units you can choose your requested data in the corresponding pulldown menu by mouse click or you can compare with the preset values. The following values are preset:
Material plate: 1.4401
Material gasket: NBR-HT
Material frame: St37-2, DIN
Max. operating pressure: 10 bar
Plate type: free
Gap/Side: free
Series/passes: fix 1
If you want to calculate just one certain plate type (for instance only size FP 14), you can preset it in field plate type.
In field gap/side, you can choose if to calculate up to a max. number of gaps (Max), with a min. number of gaps (Min) or a fix number of gaps/side (Fix). If you do not choose anything, always the item free number of gaps (free) is preset.
Under series/passes you can also choose if to calculate up to a max. number of series/passes (Max), with a min. number of series/passes (Min) or a fix number of series/passes (Fix). If you do not choose anything always the item fix number of series/passes (Fix) (1 pass design) is preset. Series/passes stand for the number of parallel gaps, arranged in series (multi-pass design).
Only multi-pass units with same number of series/passes on hot side and cold side can be calculated.
