Humidifier - Intelligent Modulation
Humidification is provided by an electrode boiler. The sealed humidifier design ensures that only clean sterile steam
is supplied to the conditioned area and corrosive salts and minerals are held in the disposable bottle. The steam is
distributed through a sparge pipe fitted to the coil assembly.
Featuring modulating capacity output control as standard, the system provides continuous modulation of steam output
in response to a proportional control signal. The output control range is 20%-100% of the humidifier rated value and
is designed to give an approximate steam output of +/- 3% at 25°C at the sensor, thus ensuring precise control of the
conditioned space.
The cylinder operating life time is automatically optimised via the integrated water conductivity sensor, which combined
with the controls monitors and regulates the water refill cycle to reduce excessive salt deposits and the progressive wear
of the cylinder.
All humidifier parameters and alarms are accessible and adjustable via the microprocessor display keypad unit, main
features include:
• Supply water conductivity (µS/cm)
• Actual steam output (kg/h)
• Required steam output (kg/h)
• Actual current rating (A)
• Required current rating (A)
• Status mode (Start Up, Running, Filling, Draining)
Water Conductivity & Cylinder Type Conductivity is a measure of the ability of water to pass an electric current,
measured in micro Siemens / centimetre (µS/cm). 3 different cylinders are available which correspond to the supply
water conductivity.
Matching the correct cylinder type with the conductivity of the supply water ensures optimum performance and increases
the life span of the cylinder.
1 Low Conductivity (Soft Water)
2 Standard Conductivity (Moderate/Hard Water)
3 High Conductivity (Very Hard Water)
As standard the humidifier is fitted with the standard conductivity cylinder which covers the majority of water supplies.
Where the water conductivity is known, please specify at order. For further details please contact Airedale.
