Technical properties
Airend
The SCR-PM series compressors are equipped with highly efficient ALLY WIN airends, which were designed in Germany and have several international patents.
ALLY WIN airends are equipped with top bearings and ensure long life and high air compression efficiency.
Lossless direct drive 1:1
Thanks to the direct connection of the airend to the electric motor, the SCR-PM series compressors operate without any energy loss in the transmission unit.
Compared to compressors with V-belts, coupling or gearbox, this eliminates any maintenance and, in addition to energy savings, the user also saves on machine servicing.
MORE ABOUT DIRECT DRIVEPM motor with IE4 efficiency
The SCR-PM compressor series uses state-of-the-art oil-lubricated permanent magnet motor technology, which, due to its design, has an extreme efficiency that exceeds the IE4 efficiency requirements of IEC EN 60034 and exceeds the conventional IE2 efficiency motors used as a standard solution for variable speed compressors by an average of 3%.
In addition, the design of the PM motor does not contain any bearings, which eliminates the aspect of motor maintenance.
MORE ABOUT PM MOTORSpeed control by frequency converter
The SCR-PM compressors are equipped with state-of-the-art INOVANCE frequency converters, which allow them to maintain the required output pressure and adapt the speed of the drive unit to the immediate needs of the compressed air supply. Thanks to this modern compressor control system, idling is significantly eliminated and energy savings of tens of percent are achieved.
MORE ABOUT FREQUENCY CONVERTERSCR9000 electronic controller
Modern system for controlling the operation of screw compressors with a comfortable 7" color touch screen and has the following functions and features:
- button control
- display of all necessary parameters about the operation of the machine
- indication of operational warnings and alarms
- alarm history for machine fault analysis
- user levels via passwords
- practical display of electricity consumption
- weekly schedule with 5 time slots for switching the compressor on and off
- automatic restart after power failure
Speed control fan
The SCR-PM compressors have a second frequency converter to control the speed of the cooling fan motor. This system provides additional energy savings when less or no cooling of the oil and discharge air is required.
MORE ABOUT FAN MOTORPipes instead of hoses
On the SCR-PM compressors, you will only find metal pipes instead of traditional flexible hoses. This saves you on future hose replacements and eliminates the risk of hose rupture and subsequent air or oil leakage as much as possible.
Efficient oil separation
Oil separation system ensures perfect compressed air output quality with a peak oil content of <3 ppm. The oil is separated by a three-stage separation system using centrifugal force, gravity effect in a vertically oriented oil receiver and a high-quality separation filter.
