Ozwater with the "Energy saving with SINAMICS G150" exhibition model

The exhibition model "Energy saving with SINAMICS G150" clearly demonstrates the energy-saving potential when using the SINAMICS G150 variable-speed drive converter for pump, fan and compressor applications. This energy-saving potential is up to 50 %. Not only this, variable-speed operation has an additional and significant benefits - for example, the pumped medium flows more smoothly, there are significantly less gas bubbles in liquid media and the pipeline temperature rise is significantly lower.

Design and dimensions of the model

"Energy saving with SINAMICS G150" comprises a SINAMICS G150 drive unit (Type C, 110 kW power rating, 400 V, dimensions 430 x 680 x 2380 (WxDxH in mm), weight 230,5 kg) and the actual operational model. This operational model comprises two separate pump circuits. For one of the pump circuits, the flow is mechanically regulated using a throttle; and for the second pump circuit, the motor speed is adapted using the SINAMICS G150. In this case, displays indicate the different power requirements of the two control techniques.
The pump model has the following dimensions 1330x800x2100 (WxDxH in mm) and a weight of 755 kg. The pump circuits are filled at the exhibition/demonstration site using a hose supplied with the model.

The statements

The model communicates the following core messages:
- variable speed operation of pumps, fans and compressors saves up to 50 % power
+ precise processes are ensured
+ the stress on the mechanical system is relieved as a result of soft starting and stopping
+ unfavorable operating states are avoided

SINAMICS G150 is precisely the optimum drive unit for this purpose

This is because it has been optimized for pump, fan and compressor applications, and allows the advantages of variable-speed operation to be especially simply and efficiently used. As a result of its cost-effective concept and short delivery times, often, the pay-back time for SINAMICS G150 is just a few months after the decision is made to select a variable-speed drive system. The operating company can then enjoy the power saved as pure profit.
