Product detailed description
Thirty-seven kilowatts at eight bar delivers 7,350 l/min — practically the same as at seven. At this size the gap between seven and eight bar is the smallest in the range: just 50 l/min.
Why 8 bar
Fifty litres a minute is under one per cent of output. The extra bar, though, costs around seven per cent in energy. So choose eight bar only when the system needs it — not "to be on the safe side". Control goes down to 1,600 l/min.
| The same 37 kW machine at three pressure settings | |||
|---|---|---|---|
| Order code | Pressure | Free air delivery (l/min) | Loss against 7 bar |
| SCR-37/7EPM | 7 bar | 1,650 – 7,400 | 0 % |
| SCR-37/8EPM — this machine | 8 bar | 1,600 – 7,350 | 1 % |
| SCR-37/10EPM | 10 bar | 2,300 – 6,500 | 12 % |
Dimensions 1,530 × 1,100 × 1,370 mm, weight 850 kg, outlet R 1½" and noise 70 dB(A) are identical at all three settings — it is one and the same machine.
How it differs from its neighbours
Below it sits SCR-30/8EPM with 6,100 l/min, above it SCR-45/8EPM with 9,400 l/min. At eight bar the two neighbouring classes differ by roughly a fifth in output, so the choice tends to be about headroom for the future rather than today’s demand.
What is inside
Permanent magnet motor
Magnets instead of a cage: efficiency exceeds IE4 and takes 5 to 6 % off consumption against IE2. On a machine delivering 7,350 l/min that adds up faster than you would expect.
Direct drive through a taper coupling
The airend sits directly on the motor. A slipping belt would quietly eat into 7,350 l/min and you would only notice on the bill; here there is none.
Frequency inverter
Workshop demand fluctuates — so the inverter reduces speed instead of blowing off the excess. The machine covers the 1,600 to 7,350 l/min band without a single shutdown.
Screw airend
The new airend is quiet and efficient — on 37 kW the sixteen percent improvement shows up in consumption before it shows in noise, though that is 70 dB(A) here.
SCR9000 controller
You schedule when the machine should run and it starts and stops itself. Over RS485 you connect it to remote monitoring, and it handles a cascade of up to sixteen units.
What the machine needs in the plant room
At 7,350 l/min you have 441 m³/h, a volume at which heat recovery is worth considering — a compressor this size heats the plant room on its own. Noise of 70 dB(A) already assumes a separate room rather than a corner of the hall.
| SCR-37/8EPM — figures for the plant room design | |
|---|---|
| Free air delivery | 7,350 l/min · 441 m³/h |
| Speed control range | 1,600 – 7,350 l/min (from 22 % of output) |
| Ventilation required | 9,000 m³/h |
| Dimensions L × W × H | 1,530 × 1,100 × 1,370 mm |
| Weight | 850 kg |
| Compressed air outlet | R 1½" |
| Noise at 1 m distance | 70 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
If you are torn between 37 and 45 kW, what usually decides it is planned growth in production, not today’s draw. The figures for both sit side by side in the table in the SCR-EPM range. A receiver for a machine this size you will find in air receivers.
Under one per cent of the air for seven per cent of the consumption. Here the extra bar really is not worth buying "just in case".
