• Insulation class:
I.
• Protection grade
: IPX0
• External structure in ABS thermoplastic material
• Technical features of the heat exchanger
:
-
Max pressure of the hot or cold water for water fan coil:
1600 kPa - with valves: 1000 kPa.
-
Min pressure of the hot or cold fluid: It is the one indicated by the designer/installer for
the correct functioning of the system
-
Min/max water temperature:
5/85 °C
-

• Technical features of the fan motor
:
-
With each EST fancoil unit there is the possibility to have different air volumes, ac-
cording to the use requirements. The relevant nominal air capacities are indicated
on Enclosure 3 of this manual and they are referred to standard fancoil units, with
clean filters, at the temperature of 20 °C, at sea level and without external static
pressure.
-
EST technology is composed by a brushless motor combined to a dedicated
electronic device (inverter), managed by specific regulators. The controller uses
a modulating signal with 0-10Vdc tension in order to regulate the fan speed.
