5.5. Countercooling
Notice:
Observe the laws and regulations of the water distribution company valid in the
location where the unit is operated.
For applications near the ambient temperature, the cooling coil
must be connected to the water mains.
 Using tubing, connect the cooling coil (25a) to the tap water
supply, and lead the tap water in a sink through the return
connector (25b).

A specific water flow rate of 100 ml/minute is sufficient to
compensate for the characteristic temperature.

For applications near ambient temperature (20 °C), the cooling
water temperature should at least be 5 °C below the working
temperature.


By installing the MVS controller (26)
and a solenoid valve (27), sudden
temperature increases can be rapidly
reversed by tap water flowing through
the built-in cooling coil.

For applications requiring constant
near-ambient temperature, tap water is
thus only used in small amounts.
The circulator provides the necessary
control pulse via the connector (15).

FD200 Flow-through cooler
Order No. 9 655 825
The FD200 is suitable as cooling device for liquids in closed circuits
(loops).
This unit is integrated in the return flow circuit from the external
system connected to a circulator, and continuously withdraws heat
from the liquid.
