Since the first Pot Tending Machine commissioned by ECL™ 50 years ago, all the new options, tools and technical solutions have been conceived and designed only to meet with smelters’ challenges: reduce energy consumption and consequently allow significant cost savings and ensure safe and secure operations.
In close collaboration with a world-class air compressor designer and manufacturer, ECL™ has then developed and equipped its Pot Tending Machine with a new standard of air compressor: the twin air compressor. Instead of just one big energy-intensive compressor, two smaller and lighter compressors are in most cases used separately (anode changes), except for tapping operation. By running them alternately at only 90% of their full capacity, there are definite energy savings with the additional benefit of a longer operational life for the compressor. Furthermore, the size and weigh of this new standard greatly ease maintenance operations.
