Part 3 Description
The electronic regulator is a controller specially designed
for CA-dryers. It operates on the basis of micro
processors. Data as cooling temperature, pressure within
cooling circuit, ambient temperature as well as CA-dryer
specific parameter are processed by the electronic and
therewith the actual operational state of the unit is
determined.
If it is allowed due to the measuring data, the cooling
compressor is stopped for a predetermined time. The
pulsating measuring of the temperatures (multiple per
second) and the function of the aluminium-heat ex-
changer as cold store enables the quick reaction on load
changes without allowing dew point peaks to exceed the
max. adjusted nominal value.
Depending on loads the electronic regulator additionally
regulates the condensate drain to avoid compressed air
losses.
The electronic regulator sets the pressure dew point on
max. 3°C.
The electronic regulator sets the pressure dew point on
max. 7 °C.
The electronic regulator sets the pressure dew point in
dependence to the ambient temperature at the location,
to keep a relative humidity below 40% at the CA-dryer
outlet.
Attention!
To enable this, it is necessary that the ambient tempera-
ture of the whole CA-network are not below the tem-
peratures at the location of the CA-dryer.
