In recent years, many customers have started to use inverter driven pumps as a means of reducing energy costs, and to incorporate a more 'green' ethos into their plant equipment policy.

Invertors work by reducing the speed of a pump, such that a larger pump may be used at reduced speed; reducing energy costs drastically, and allowing capacity for system expansion without replacing the pump.

The system works due to the ratios of
Speed : Duty : Energy Consumption; it is known that if the speed is reduced by half, the duty will reduce to one quarter, but the energy consumption will be only one eighth. Pump wear is also significantly reduced.

The initial investment is higher than for a smaller, fixed speed pump, but for a Heating or Chiller Pump which runs continuously, costs are quickly recouped in energy savings on an ongoing basis.
