OPERATING LIMITS
(1)
With room temperature of +22˚C
(2)
For humidifier module, max. pressure = 2 bars
(3)
Minimum working temperature depends on the thermal carrier used.
If operation of the unit has to be guaranteed with water temperatures of less than 1˚C or stopping of the unit at room temperatures
of less than 1˚C, ethylene glycol must be added to the fluid in the hydraulic circuit in sufficient quantities to avoid freezing.
