Product detailed description
The 37 kW machine set to ten bar gives 6,500 l/min. Against seven bar it loses only 12 % — the smallest pressure penalty in the range. So when ten bar genuinely is required, this size takes it best.
Why 10 bar
Ten bar means 6,500 l/min. Watch the lower limit, though: at this setting the manufacturer quotes 2,300 l/min, or 35 % of output, whereas at seven and eight bar it is only 22 %. The control range here is therefore markedly narrower, and at low night demand the machine will shut down more often.
| 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 | 8 bar | 1,600 – 7,350 | 1 % |
| SCR-37/10EPM — this machine | 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
The smaller SCR-30/10EPM gives 5,200 l/min but regulates down to 1,300 — with fluctuating demand it may be the more flexible choice. The larger SCR-45/10EPM adds 1,500 l/min, but its lower limit is higher still.
What is inside
Permanent magnet motor
A closed oil circuit and a bearingless design mean one less service item. On 37 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 35 % of output, that is 2,300 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 6,500 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
Ten bar, 6,500 l/min, that is 390 m³/h, and ventilation of 9,000 m³/h. The combination of high pressure and a narrower control band means the machine will shut down at low demand — the receiver here has to smooth not only the peaks but these cycles as well. We will gladly size the vessel to your demand profile.
| SCR-37/10EPM — figures for the plant room design | |
|---|---|
| Free air delivery | 6,500 l/min · 390 m³/h |
| Speed control range | 2,300 – 6,500 l/min (from 35 % 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
It is precisely at ten-bar settings above 30 kW that a pair of machines deserves thought: one holds the base load, the other comes in at peak, and the lower control limit stops being a problem. A cascade of up to sixteen units the controller handles itself — details in the SCR-EPM range; above 45 kW the SCR-EPM2 range continues.
It only goes down to 2,300 l/min. If your demand falls to nothing overnight, consider the 30 kW instead, or two machines in cascade.
