There was a noticeable increase in output with lower energy consumption. We now achieve up to 75% concentration with minimum product loss which is very good considering the fermentation conditions.” GILBERTO GUALTIERI, SANTA TEREZINHA
Lower total cost of ownership
The upgrade increased throughput by about 40 m3 per hour. In terms of capacity, Santa Terezinha received the equivalent of a third machine at 40% of the cost. No additional space was needed and no new installation or infrastructure. In addition, the Equipment Upgrade resulted in energy savings.
Maintenance costs are the same as for the original machines and spread over a higher throughput, i.e., the cost per produced litre of ethanol goes down which, in turn, means lower total cost of ownership.” JOAO ROSENSTOCK, ALFA LAVAL PARTS & SERVICE, BRAZIL
