10.6 Rotation direction indicator - Phase controller
Description
The phase controller enables permanent and easier verification of the rotation direction of the machine by
means of a diode. This prevents any risk of physical damage by disabling the compressor start up in case of
phase reversal or if a phase is disconnected and indicates a machine fault.
Marking on the motor of the standard machine version identifies the motor fan rotation direction during the
start up phase. Work on the electric network or the machine may change the rotation direction and damage
the compressor which must be detected quickly.
10.7 Special oils
Description
Different oils meet different needs:
4000 hours oil : longer interval between 2 drainage operations - 4000 hours under standard conditions of
use.
8000 hours oil : longer interval between 2 drainage operations - 8000 hours under standard conditions of
use.
Food Grade Oil: use of the compressor in the agricultural food & beverage industry.
Note:
If this option is chosen on a machine that has previously run on standard oil, the flushing procedure must
first be strictly complied with.
Overview
4000 and 8000 hours oil
The qualities of these oils enable the maintenance planning schedule to be based on main drainage
operations of 4000 or 8000 hours (under standard conditions of use).
The maintenance tasks are consequently less frequent, thus making for certain savings, such as the
availability of the equipment and lower operating cost of the compressor.
Food Grade Oil
This oil has been specially developed for use as a lubricant that may come into contact with foodstuffs.
10.8 Centrifugal water separation
Description
This device enables the separation of condensates formed in the air cooler.
