6.4. Maintaining a constant water level / Counter cooling
For cooling tasks near the ambient air temperature the liquid
level/cooling set can be used for counter cooling.
By special pipe routing, cool faucet water is continuously supplied to
the water bath, while at the same time, the heated water is drained
via the overflow connection of the Level/Cooling set.
 A specific water flow rate of 100 ml/minute is sufficient to
compensate for the characteristic temperature.
Caution:
Securely attach all tubing to prevent slipping.
Observe the laws and regulations of the water distribution company valid in
the location where the unit is operated.
Use of the liquid level/cooling set for a continuous supply of
faucet water:
1. to keep the water level constant, especially for
applications up to the boiling point (supply of faucet
water only in the amount of evaporation losses).
2. for counter cooling of cooling tasks near the ambient
surrounding temperature (cool faucet water is
continuously supplied to the water bath, while at the
same time, the heated water is drained via the overflow
connection of the liquid level/cooling set).
