Welcome to OPAL

Motor systems have a significant potential of energy savings. This application has been developped to find the most cost-effective actions to reduce energy consumption of motor-driven pump systems.

NEW: includes motors compliant to the new efficiency standard IEC 60034-30:2008

How to increase efficiency?

To increase the energy efficiency of an electric motor system the following steps are generally required:

• acquire the component and the load profile data of the drive system.
• examine different saving actions and compare the results.

Introduction to OPAL

The aim of this software is to provide a simple and easy-to-use tool that helps users to find the most cost and energy efficient solution for purchase and replace decisions of motors and the variable speed operation of pumping systems. It is planned to also cover the fan systems in a future release of this software.

The current version offers you the following options:

• Searching the motor catalog OPAL gives you access to the EuroDEEM database containing the performance data of more than 10 000 motors. Based on your motor specifications -- kilowatt rating, synchronous speed, degree of protection, operating voltage and manufacturer -- the software will list available motors, ranked in descending order of full-load efficiency.
• Comparing motors OPAL can be used to compute the energy consumption and savings to support replace or purchase decisions of any motor combination: such as a new EFF1 instead of a standard EFF3 or an improved Efficiency EFF2 motor model or a motor of some specific manufacturer. The evaluation is based on a user definable load profile.
• Evaluating VSD operation OPAL lets you compare the energy consumption and savings of pumping systems running at constant and variable speed with a given load profile.
