Compared to mechanical control with butterfly valves etc., flow rates can be controlled far more accurately and reaction times are shorter – when variable speed drives are used. E-pumps adjust the flow rate to match actual demand much faster and with greater precision in response to demand fluctuations. Variable speed pumps are more energy efficient, and they also help stabilise the process.

What's the Catch? Overcoming Obstacles in Process Optimisation...

If that is the case, why then have users not taken advantage of all optimisation options? There are a number of possible explanations:

• Decisions are based on payback time: at many companies, the maximum payback period is 2 to 3 years. The payback period however is basically a risk management tool, but says nothing about ROI. NPV is the method to use for that purpose.

• Lack of a basic technical understanding: the people responsible for energy management cannot present the information in a way that managers without engineering expertise can understand.

• Spending constraints: approval is not given for any investment that is not absolutely necessary.

• Lack of human resources: opportunities to save energy are understood, but no one has time to take the appropriate action.

• Investment only when faults occur: reinvestment is often only considered when systems actually fail. In such situations, the new system must be available quickly and cost as little as possible. No thought is given to lifecycle costs.

• Failure to allocate costs: many companies only know what their overall energy consumption is. No consumption data is available for individual equipment. In many cases, personnel costs for maintaining old equipment is not allocated to the specific items.

How Operational Excellence Works – Process Optimization Techniques

Without information on energy consumption, and labour costs for the existing equipment, there is no way to identify inefficient equipment, and a financial evaluation of equipment optimisation is not possible...
