Service unit combination MSE6-D2M

Automatically save energy in compressed air systems with the MSE6-D2M! The MSE6-D2M monitors consumption, blocks the compressed air during unproductive times and reduces the pressure to 0 bar. For a second compressed air line, you can connect it to the new MSE6-C2M or a CPX terminal.

Manufacturing with the best energy balance

The energy efficiency module MSE6-D2M constantly monitors the compressed air consumption, shuts off the compressed air after production has stopped for a certain amount of time and reduces the system pressure to 0 bar. The module can be connected to a MSE6-C2M or a CPX terminal as an extension for a second string, without additional fieldbus nodes.

Return on investment after only 1 to 1.5 years

Let's assume that a machine is in operation 250 days per year based on two shifts and has a compressed air consumption of 2,000 l/min at 6 bar and a leakage rate of 10%. If the compressed air is not shut off during the 4,000 hours of non-production time, 48,000 Nm³ is simply lost. This would be an expensive luxury that would cost you €912 and 3.2 tonnes of CO2emissions. By having the MSE6-D2M switch off the system during non-production time, you can easily save these costs.
And since the energy efficiency modules incorporate additional functions such as those of the classic pressure regulators MS6-LR, on/off valves MS6-EE, pressure sensors SPAU and flow rate sensors SFAM , the amortisation period is further reduced. Especially if you consider the costs of regular manual leakage detection.
The bottom line is that a more conscious use of compressed air pays for itself in less than 1 to 1.5 years.

Sample calculation:

  • Costs for compressed air: €0.019/Nm³
  • Consumption of the machine: 2,000 l/min
  • Production/day: 16 h
  • Production/year: 250 d
  • Leakage rate: 10%
  • Working pressure: 6 bar

10% at 2,000 l/min* = 2,000 l/min ( fi = 0.2 Nm³/min )

Non-production time
(365 d · 24 h) - (250 · 16 h) = 4,760 h
4,760 h - 760 h** = 4,000 h (240,000 min)

Leakage during non-production time (at 6 bar)
0.2 Nm³/min - 240,000 min = 48,000 Nm³

Savings during non-production time
when switching off the pressure
48,000 Nm³ · 0.019 €/Nm³ = €912
