Chilled water units
Hydraulic circuit
Each unit is provided with one hydraulic circuit.
The unit is provided with a 3-way modulating
valve, complete with incremental motor for the
water flow control to the coil; the opening or clos
ing signals, generated by the electronic control,
manage the valve in order to keep the ambient
temperature at the required value.
Through a series of menus it is possible to set all
parameters on the control for a correct adjust
ment, i.e. set-points, proportional bands, pro
portional or proportional+integral adjustment, in
tegrating factor and valve feature. It is possible to
adjust the valve manually in closing position (coil
side) by means of a suitable wrench.

Direct expansion air-condensed unitswith high precision control
Refrigerating circuit
Each unit is provided with a single refrigerat
ing circuit.. This is similar to the version's re
frigerant circuit (see para. 2.1), but a modulat
ing hot gas bypass valve is present. This valve
permits high precision evaporating tempera
ture regulation.
For other carachteristics, see para. 2.1.
2.8 - Hiflex Constant versione W
Direct expansion water-condensed unit with high precision control
Refrigerating circuit
Each unit is provided with a single refrigerating circuit..This is
similar to the version's refrigerant circuit (see para. 2.2), but a
modulating hot gas bypass valve is present. This valve permits
high precision evaporating temperature regulation.
For other carachteristics, see para. 2.2.
