Water Conductivity &
Cylinder Type
3 different cylinders shall be available which correspond to the supply water conductivity.
The cylinder type shall be matched with the standard conductivity of the supply water to
ensure optimum performance and increases the life span of the cylinder.
1 Low Conductivity (Soft Water) 100 to 350 µS/cm
2 Standard Conductivity (Moderate/Hard Water) 350 to 750 µS/cm
3 High Conductivity (Very Hard Water) 750 to 1250 µS/cm
Conductivity is a measure of the ability of water to pass an electric current, measured in micro
Siemens / centimetre (µS/cm).
As standard the humidifier shall be fitted with the standard conductivity cylinder which shall
cover the majority of water supplies. Where the water conductivity is known, please specify
at order. For further details please contact Airedale.
CAUTION
The supply water pressure
to the humidifier assembly must
be between 1
-
8 barg.
Safe
Operation o
f
Humidifier
To protect the humidifier bottle from dangerous pressures in event of the steam supply
pipe becoming blocked, a tundish is installed between the water inlet solenoid and the
cylinder to act as a reservoir and to feed water to the humidifier inlet manifold as required.
CAUTION
An overflow weir is incorporated in the common fill/drain tundish. Any pressure
build up in the cylinder would be allowed to vent through the tundish to
atmosphere.
IMPORTANT
It is MOST IMPORTANT that the steam distribution pipe is not damage
d or kinked at
any time to avoid the risk of unacceptably high pressure building up in the electrode
bottle
