Buckman’s energy-saving drive pays off

This equates to 4 million kg of CO2 eliminated, 5.5 million litres of water saved and 2.7 million kg of coal not used.
The pair teamed up in 2012 to reduce electricity and water consumption at Buckman’s Hammarsdale, South Africa, facility, monitoring Buckman’s primary cooling tower.
The cooling tower system comprises two fans and two pumps, which originally ran at maximum speed for 24 hours per day from Monday morning until Saturday morning.
Once Energy Drive’s solution was installed on the four motors; sensors provided variable frequency drives with the information necessary to regulate the speed of the motors depending on the temperature required. When the system reaches the desired temperature, the pumps and fans slow to the optimal speed to ensure that energy is not wasted.
Mukesh Ramatar, plant manager for Buckman South Africa, said: “One of the best things about variable speed drives is that they could be installed across all cooling tower systems and chiller systems globally, which could exponentially impact our energy savings and sustainability efforts.”
