Teflon-free compressor elements
The rotors of the compressor elements have an epoxy-based coating.
Automatic water shut-off
A water shut-off valve is provided in the cooling water system to shut off the system when the compressor is
not in operation.
Energy recovery
The compressor is provided with an Atlas Copco energy recovery system to recover the major part of the
compression heat in the form of hot water.
SPM monitoring
A number of vibration sensors are provided on the drive motor and compressor elements. The readings can
be called up on the display of the Elektronikon regulator.
High ambient temperature (HAT)
The compressor is specially designed for continuous operation under humid and high ambient temperature
conditions. The maximum ambient temperature is 50˚C (122˚F).
Prepared for MD dryer with or without Pressure Dewpoint Sensor and/or Low load heater
The compressor is prepared for easy connection of an MD dryer. Plug in the connectors and connect the piping
to the MD dryer and the compressor/MD combination is ready to start. The proper piping, the wiring and the
connectors will be delivered with the MD dryer.
The settings and parameters for the MD dryer are downloaded in the Elektronikon regulator of the compressor.
Anchor pads
Steel plates, fitting in the forklift slots, and bolts are shipped loose with the compressor. With these plates
and bolts, the compressor frame can be fixed to the floor.
Anti-condensation heaters
Electric heaters are installed in the motor windings and connected to the compressor cubicle. When the
compressor is stopped, the heaters are automatically switched on. The heaters in the motor will prevent
condensation during stand-still.
PDP sensor
The pressure dewpoint of the compressed air leaving the IMD dryer is continuously shown on the display of
the Elektronikon regulator. This allows to monitor the performance of the dryer and to make sure that the
compressed air is dry enough for the application.
Low load compensator
The low load installation allows the dryer to be operated in low load conditions of the compressor. At these
conditions (compressor in unload) the pressure dewpoint is maintained by purging a small amount of heated,
dryed air through the rotor of the dryer.
