Emotron variable speed drives are specially designed for these applications. They automatically adjust operation to the desired flow or pressure by controlling the motor speed. This reduces the energy consumption significantly compared to using valves to control flow and pressure.

Other energy-saving features of Emotron variable speed drives include:
• A unique monitoring function immediately detects situations that can reduce efficiency, for example if a pipe is blocked or a valve is not opening fully.
• A pause function reduces the motor speed to zero when pump operation is not needed to maintain the required pressure.
• Automatic pump rinsing cleans sludge out of the impeller and the pipes, which would otherwise reduce the efficiency of the pump.
Environmental benefits with the technique/products/services:
- Less use of energy

Company description:
Emotron develops solutions for protecting and controlling machines and processes driven by electrical motors. The focus is on energy savings in the operation of pumps, fans and compressors, which are the applications highlighted by the EU´s Motor Challenge Programme (MCP) as having the greatest potential for improved energy efficiency.

The product portfolio comprises variable speed drives, softstarters, shaft power monitors and drive systems. Development and manufacturing takes place at the head office in Helsingborg, Sweden, and at the subsidiaries in Germany and the Netherlands. The company also has sales offices in China and Latin America, as well as distributors and partners all around the world.

Emotron promotes energy savings as an endorser for the EU´s Motor Challenge Programme and as a member of the Energy Efficient Companies section of the Swedish organization EnergiRådgivarna (Energy Advisors).
