9.4 Acoustic Hood (Ci 40/55).
The Ci 40/55 Dominators are available with an acoustic hood. This cabinet
helps to reduce the noise level, as well as acting as a protective cover for the
compressor. Ci75 / 110 models have the hoods fitted as standard.
9.5 Clean Air Pack (Dryer).
The clean air pack provides clean, moisture free air. A refrigerant dryer is
teamed in series with a microcoalescent filter or filters to remove any moisture
and oil carry-over in the discharge air supply.
NOTE: A 240V connection must be available for wiring of the refrigerant
dryer. The dryer must be individually wired to the supply, as it is not hard-
wired to the compressor electrics.
9.6 Dirty Environment Filter (Cyclopac).
For operation in dirty environments, a heavy-duty Cyclonic air filter is offered
as an externally mounted option. (Refer Section 18).
9.7 No Neutral & Hour-meter (Ci 40/55/75)
Where no neutral facility exists at the installation location, the no neutral
option may be fitted, allowing connection with three phase power leads and an
earth lead. Also included is an hour meter to record hours run, not standard
on Ci40 / 55. As stated above, if a refrigerant dryer is incorporated, a 240V
connection for single phase power supply to the dryer is necessary.
9.8 Duplex
The Duplex is a pair of Dominators mounted on a common twin air receiver,
approximately three times the volume of a standard air receiver. The
compressor units are controlled by either the 'Lead / Lag' Control box
providing ‘lead / lag’ operation (Refer Section 9.2) or the ‘Lead / Lag, Remote
Monitoring and Control’ box providing ‘duty / standby’ or ‘lead / lag’ operation
(Refer Section 9.1).
