SCR-45/10EPM screw compressor Power input 45 kW, displacement up to 8,000 l/min, pressure 10 bar, frequency converter, voltage 400/50 V/Hz YD
Code: SCR-45/10EPMRelated products
Product detailed description
The top of the EPM range set to ten bar: 8,000 l/min. It is the highest delivery available in this range at ten bar — and at the same time the setting with the narrowest control band of all eighteen.
Why 10 bar
Ten bar gives 8,000 l/min against 9,500 at seven, 16 % less. The lower control limit, however, is 3,000 l/min — a full 38 % of output. The machine will not go below that, so at low demand it will shut down and restart.
| The same 45 kW machine at three pressure settings | |||
|---|---|---|---|
| Order code | Pressure | Free air delivery (l/min) | Loss against 7 bar |
| SCR-45/7EPM | 7 bar | 2,500 – 9,500 | 0 % |
| SCR-45/8EPM | 8 bar | 2,400 – 9,400 | 1 % |
| SCR-45/10EPM — this machine | 10 bar | 3,000 – 8,000 | 16 % |
Dimensions 1,530 × 1,100 × 1,370 mm, weight 890 kg, outlet R 1½" and noise 72 dB(A) are identical at all three settings — it is one and the same machine.



How it differs from its neighbours
The smaller SCR-37/10EPM delivers 6,500 l/min and goes down to 2,300. If your demand fluctuates, it may suit you better than the 45 kW. If less pressure would do, the same machine as SCR-45/7EPM adds 1,500 l/min.
What is inside
Permanent magnet motor
A closed oil circuit and a bearingless design mean one less service item. On 45 kW it adds 5–6 % of saving against an ordinary IE2 motor on top of that.
Direct drive through a taper coupling
A taper coupling transmits the power with no belt losses. On a machine meant to run daily, what matters most is what does not need checking.
Frequency inverter
It comes down to 38 % of output, that is 3,000 l/min, and does not have to cycle. The soft start puts no more load on the supply than normal running.
Screw airend
A reground profile and optimised ports. On a machine giving 8,000 l/min the airend is the one part that cannot be improved afterwards — which is why it is new.
SCR9000 controller
A graphical schematic shows what is happening inside, the service schedule reminds you about the oil change. It runs a cascade of sixteen compressors with no separate control cabinet.
What the machine needs in the plant room
Eight thousand litres a minute at ten bar is 480 m³/h. The high lower control limit (3,000 l/min) together with that volume means the machine needs either steady demand or a substantial receiver. Ventilation of 9,000 m³/h and a weight of 890 kg are fixed.
| SCR-45/10EPM — figures for the plant room design | |
|---|---|
| Free air delivery | 8,000 l/min · 480 m³/h |
| Speed control range | 3,000 – 8,000 l/min (from 38 % of output) |
| Ventilation required | 9,000 m³/h |
| Dimensions L × W × H | 1,530 × 1,100 × 1,370 mm |
| Weight | 890 kg |
| Compressed air outlet | R 1½" |
| Noise at 1 m distance | 72 dB(A) |
| Supply voltage | 400 V / 50 Hz |
Equipment
- permanent magnet motor above IE4, oil-cooled, IP65 protection, no bearings
- direct drive by taper connection — no belts, gearbox or coupling
- vector-controlled frequency inverter, 25 to 100 % speed range
- the inverter drives the cooling fan as well
- new airend with a rotor profile developed in Japan
- SCR9000 controller with touch display, weekly timer and cascade of up to 16 machines
- nano-scale intake filter at 99.9 % efficiency, 0.1 µm oil filter
- separator with oil carry-over below 3 ppm
- all-steel internal pipework instead of rubber hoses
- soft start — the current never exceeds the rated value
At this setting a cascade of two machines makes more sense than anywhere else in the range — precisely because of that high lower limit. The controller handles up to sixteen compressors without a master panel, as described in the SCR-EPM range. Above 45 kW the SCR-EPM2 range continues.
Only down to 3,000 l/min. If your plant goes quiet overnight, two smaller machines will be more economical than one this size.
