Inverter control of pumps and the correct control strategy can reduce energy consumption by 30-50%.

A frequency inverter adjusts the speed of an electric motor by varying the frequency and voltage, frequency is directly related to motor speed, so if an application does not require full speed, the inverter can be used to adjust the motor speed to meet the demand.

Many pumps operate under variable load, for example heating and chilled water pumps which are designed to provide sufficient flow under peak conditions, as load changes the inverter can adjust motor speed to efficiently meet reduced demand.

There are many well proven applications where Inverters can deliver increased energy efficiency. In pump and fan installations energy consumption can be halved if motor speed is reduced by 20%.

Refrigeration compressor part load efficiency can be improved if an inverter is used to provide capacity control and the efficiency of chillers increased if inverters and floating head pressure control are sensibly applied.

It is important that if optimum energy results are to be achieved the installer understands the process to which the inverter is being installed. A poor installation can cause damage to the equipment or impact on the process , the control strategy should be discussed and the appropriate sensors utilised to reflect variations in load.

Excalibur have been installing Inverters into building services, process and refrigeration applications for over 20 years, much of our work is to business critical equipment where resilience is the highest priority.

Where necessary we manufacture inverter control panels which incorporate a Bypass / Fallback control to ensure continuity of operation and no single point of failure.
