7.15.2 Configuration examples
Example 1, favorable configuration:
−
LAUDA Integral XT 750 with connected metal double-shell vessel (20 L),
−
2 x 2 m metal corrugated hose, 20 mm clearance (M30 x 1.5),
−
no by-pass,
−
oil LAUDA Kryo 55, in temperature range -50...220 °C,
−
pump on Level 6.
Example 2, unfavorable configuration:
−
LAUDA Integral XT 150 with connected glass double-shell vessel (5 L),
−
2 x 4 m metal corrugated hose, 10 mm clearance,
−
no by-pass,
−
oil LAUDA Kryo 55, in temperature range -50...220 °C,
−
pump set to pressure control at 1 bar.
On account of the too little flow, caused by the low pressure (1 bar) and the unfavorable hose ar-
rangement (8 m length with only 10 mm clearance), the warning messages
WXArn 007
and
WXArn 332
are triggered. The control is unstable and only very slow in response.
Example 2, improved configuration:
−
Metal corrugated hose shortened to 2 x 3m , but 10mm clearance could not be enlarged,
−
with by-pass, see above for setting,
−
pump increase to pressure control at 1.3 bar .
Flow was better and therefore no more warning messages. Also the control can be adjusted better, but
a larger clearance in the hoses is more effective for optimum operation.
