AFTER-COOLER
An integral after-cooler, with water separator (1), is
available to reduce the outlet air temperature to ambient
plus 10°C (18°F) and cut water content to a mere 15%.
This performance can be obtained under optimal
atmospheric conditions.
When an after-cooler is used in an application where the
temperature is critical the air outlet temperature can be
monitored by the compressor controller.
A warning can be set at a value between 0°C and 115°C
(=default value) and a shut-down can be set at a value
between 0°C and 120°C (= default value). The operator
has authority to modify these values so the process can be
guarded and kept in a safe condition under all
circumstances.
See also table Fault codes on page 50.
The installation includes a by-pass over the after-cooler.
For applications that demand quality air, a fine filtration
unit (2) can be specified with the after-cooler package.
This will remove oil and particles down to 0.01 mg/m3.
For purer, but not breathing, air, an active charcoal
filtration unit (3) can be specified with the after-cooler
package. This removes oil and oil vapour content to 0.003
mg/m3.
