A leading PCB manufacturer was asked to carry out an experiment to compare the real life efficiency savings of an existing application where an AMX655 with AC induction motor and inverter was currently used, compared with the new permanent magnet driven AVF range.

A power meter was installed and the power absorbed was compared at 3 different duty points. As shown, the greater the variation in duty points required by one single pump, the greater the savings in running costs.

The PCB manufacturer which is a key supplier to Samsung has now begun to transfer all pumps to the AVF range because of the clear demonstration of cost savings that the AVF range can provide. It wasn’t only the cost savings that impressed this particular client – the footprint of the AVF pump is smaller and they are also considerably quieter thanks to the fan less design.
