The main features are as follows:
All of the units undergo a safety test cycle to check the continuity of the protection circuit and the insulation resistance
and a voltage test (dielectric strength).
Power factor condensers are available for all Direct Expansion Models with 400/3+N/50Hz.

LIMIT VALUES FOR THE SUPPLY WATER WITHIN AN IMMERSED ELECTRODE HUMIDIFIER
Immersed-electrode humidifier
for modulating sterile steam production with automatic regulation of the concentration
of salts in the boiler to allow for the use of untreated water. It is therefore possible to use water with varying degrees of
hardness and without the need for any chemical treatment or demineralising. The humidifier has a steam cylinder, a steam
distributor (installed immediately downstream from the exchanger), water intake and delivery valves and a maximum
level sensor. Proportional control of the humidifier operation (achieved by controlling the electric current allowed to
pass through the cylinder’s electrodes and the management of salt concentration inside the cylinder) guarantee perfect
efficiency of the system, energy saving and greater durability of the components.
The steam cylinder is installed outside the air flow to avoid any heat losses. The unit’s microprocessor control indicates
when the steam cylinder has to be changed because it is empty; the steam cylinder can be, on request, the type which
is able to be inspected so that the electrodes can be routinely cleaned to remove any lime scale. The maximum steam
capacity production is adjustable within a range of values between 2 and 3 kg/h which can be selected manually.
