Variable Speed Drives

We are able to offer a substantial range of variable speed drives covering applications such as fan and pump control, as well as in clean area processing zones in the food and pharmaceutical industries.

With energy costs constantly increasing variable speed drives can provide a return on investment extremely quickly. 

Many applications still use motors in direct-online configurations running at full speed. 

If the speed can be reduced, the energy consumption costs can drop substantially.  This is particularly the case for many centrifugal fan and pump applications, as the torque required to turn them is proportional to the square of the speed.

In this case, a 20% reduction in speed can save up to 50% energy.

Major features and benefits of the variable speed drives we can offer include:

• Qualified for Energy Technology List
• Belt monitoring with or without external sensor
• Integrated PID control for fast and precise pressure control with pumps and fans
• Integrated energy meter (kWh)
• Large number of digital and analog I/Os
• Low harmonics technology (LHT) protects existing electrical installation and mains transformers against excessive temperatures
• In-built communication for fast and easy network integration
