OPTION : Secondary circuit energy
supply
This circuit has to raise the water temperature, which leaves from the
iced water group of nominal ∆T,
at the nominal flowrate at full power. The heater is an electric type
[submerged resistance in an exchanger].
The circuit is equipped with a pressure accumulator. The adjustment of the
heater is manual and linear – 0-100%. A numeric controller measures the
water temperature and adjusts the servomotor's position. You must provide
an increase of 16 A on the triphased feeding of the unit. |
