25% energy saving in wastewater transport system in Ajman
A well-known manufacturer of car components undertook a Grundfos Energy
Check to investigate what savings were possible. Focus was placed on their
large, fixed speed, cooling tower pumps that dealt with a variable load.
The energy check identified that replacing vertical multi-stage pumps,
with Grundfos NBE integral end-suction pumps, linked to a pressure transmitter
would achieve optimal efficiency.
Today instead of having fixed speed pumps, the car component manufacture have more efficient pumps controlling their system demands.
This has resulted in energy savings of 177,304 kWh and an ROI of 2.5 years
